Simply Beautiful Stewartia

In spring, when everything bursts into flower, the world is full of trees in bloom.  But springtime is also the time to plan and plant ahead for the season, anticipating flowering trees and shrubs with a different time of bloom, like Stewartias. Their large, ivory, Camellia-like flowers would be worthy of a spring show, but they arrive in late summer when gardens are in need of their beauty.

The fact is, stewartias are welcome landscape additions at just about any time, and you can find one to fit just about any size garden. They are also plants that are showy in all seasons, whether in flower or not. Their mottled bark and beautiful statuesque habits are always lovely, and in the fall you can anticipate colorful leaves. Here are some of the best of these well-behaved Asian trees and shrubs.

Japanese Stewartia

Bees pollinate the blooms of Japanese Stewartia and other species.

If you have the room, Japanese stewartia (Stewartia japonica) is an all-around great tree that offers four seasons of interest. Growing between 20 and 40 feet tall, with a pyramidal canopy, its branches have slightly toothed, ovoid leaves that are a cooling dark green during the growing season. In the fall, they flame up in shades of yellow, red, and burgundy, putting on a great show.

Before all of that foliage drama, Japanese stewartia flaunts its family relationship with camellias by pumping out beautiful, white, Camellia-like flowers.  Each bloom is at least 2 inches wide and features five to eight petals surrounding a center of golden-orange stamens. While only minimally fragrant, the flowers are maximally elegant and borne abundantly on trees that are hardy to USDA Plant Hardiness Zones 5-8. 

Japanese Stewartia develops fantastic mottled bark as it ages.

In the colder months, when both leaves and flowers are things of the past, Japanese stewartia continues to shine with multi-colored, exfoliating bark.  This bark, which peels gradually from the tree, looks a little like camouflage, but a lot more interesting, with patches of gray, sepia, tawny orange-brown, and taupe covering the trunk. It is a feast for the eyes at all times, but especially in seasons when visual interest may be at a premium.

Tall Stewartia

The large-leaved tall stewartia can reach 25 feet at maturity.

Tall stewartia (Stewartia monodelpha) is another native of Japan, hardy to USDA Plant Hardiness Zones 6-8, with characteristics similar to those of Japanese stewartia.  Young plants have a somewhat shrubby habit, but assume a tree form with age, reaching up to 25 feet tall in height.  Tall stewartia features large, dark-green leaves that turn deep red in the fall.  The bark does not exfoliate as colorfully as that of Japanese stewartia, but as the tree ages, the bark smoothes out and turns a stunning shade of cinnamon brown. The camellia-like flowers are more cupped in shape than those of other stewartias and sport attractive anthers in their centers.

Chinese Stewartia

Chinese stewartia (Stewartia sinenesis), which is hardy to Zones 5-7, can be grown in tree or shrub form.  Left to its own devices, it will reach 15 to 25 feet tall, but like other stewartias, it can be kept smaller when pruned after flowering.  The white flowers are somewhat smaller than those of Japanese stewartia but are profuse and surrounded by leaves that are reddish when emerging in spring, dark green in summer, and red again in the fall.  The cinnamon-brown bark exfoliates in strips to reveal smooth, tan underbark, sometimes with pinkish overtones. 

Mountain Stewartia

The  Asian stewartias have American cousins, the best known is Stewartia ovata, sometimes known as mountain stewartia or mountain camellia.  Native to the southeastern United States, and hardy to Zones 5-9, it is a little smaller than Japanese stewartia with a height and spread of 10 to 15 feet.  It also excels in versatility because it can be grown as a tree or a multi-stemmed shrub.  Like its Japanese relative and true to its common name, it features Camellia-like flowers and leaves that glow red and orange in the fall.  Its gray-brown bark, while attractively ridged and furrowed, does not exfoliate like that of the Japanese species.  Still, for those hankering for stewartias, but confined to smaller spaces, mountain stewartia is an excellent choice.

Stewartia Relatives

Franklinia blooms are attractive to lots of different pollinators.

Stewartia and camellia are both members of the Theaceae or tea family.  Their equally beautiful relatives include the all-American Franklinia tree (Franklinia alatamaha), which was discovered in Colonial America and now extinct in the wild. Specimens of this beautiful small tree can be found at many botanical gardens and arboreta. They are also available at select garden centers.

All the stewartias make excellent stand-alone specimens, but can also anchor partly shaded garden beds, and situations that resemble their native habitats at the edges of wooded areas. They thrive best in rich, consistently moist soil and locations that are protected from harsh winds.  To get a young specimen off to a good start, mix the soil in the planting hole with a nutritious soil amendment like Fafard Premium Topsoil, which is ideal for boosting the soil of newly planted trees and shrubs.  Water regularly while the plants establish sturdy root systems and mulch generously around, but not touching the plants’ trunks or main stems.

Carefree American Wildflowers for Sunny Summer Gardens

My favorite carefree American wildflowers of summer are untamed, grassland natives that blow in the breeze and bring color to less formal, airier plantings. Their waves of flower color glow on warm days when pollinators are most active. These are flowers that you slow down to look at along roadside meadows but are tame enough for gardens. Each year their seeds gently sprout here and there, creating beds with ever-changing character.

Fafard Premium Natural & Organic Compost Blend pack

Another welcome trait is that they require no special skills to grow. Plant them in full sun, average soil with good drainage, (Fafard Natural & Organic Compost is a good amendment to add at planting time), give them a little water on dry days, weed as needed, and they will essentially care for themselves.

Plant them together in colorful swaths or among ornamental grasses for a free and beautiful meadow effect. (Click here to learn more about meadow gardening.) Most of these American wildflowers are perennials with one annual added to the mix.

Winecups (Callirhoe involucrata, Zones 4-10) knit and weave themselves around other flowers and grasses to provide hot color with its cups of deep magenta flowers. It has a deep taproot and is quite drought tolerant, reducing the need for supplemental water. Just provide winecups with full sun and a spot of dry to average soil that drains well, and it should be happy. Expect flowers from mid to late summer.

Hairbells
Hairbells look delicate but are drought and wind tolerant.

The hairbell (Campanula rotundifolia, Zones 3-7) is named for its delicate bells of violet to pale blue that hang from slender 12- to 18-inch stems. The plants look sleight but will tolerate quite a bit of drought once established. Plant them in full to partial sun, provide average moisture, and watch them produce their pretty flowers from early to late summer.

Dyer's Coreopsis 'Mardi Gras'
Dyer’s Coreopsis ‘Mardi Gras’ is a pretty annual wildflower that self sows.

The annual Dyer’s coreopsis (Coreopsis tinctoria) bears lots of small gold or gold and burgundy daisies atop slender stems in the summer months. The 1- to 2-foot plants can sometimes flop. Planting them among upright perennials and grasses helps provide stability. Bees and butterflies love the flowers, and no special skills are needed to grow it. Just sprinkle the seed on worked ground in spring, keep it moist, and watch them sprout and grow. Expect them to gently self-sow. The variety ‘Mardi Gras‘ is extra pretty with its quilled petals of gold and maroon. Dyer’s coreopsis is also valued as a traditional dye plant (click here to learn more).

Monarch butterfly on purple coneflower

Pale purple and purple coneflowers (Echinacea pallida and E. purpurea, Zones 3-8) are valued for their beautiful large-coned daisies and wildlife benefits; few native wildflowers can beat these. They’re a snap to grow, bloom over a long period in summer, especially if deadheaded, and provide a few seedlings each year. Leave the last wave of autumn seedheads up to dry and feed winter birds.

Purple coneflower begins to bloom in early summer, has large leaves, bright purple-red flowers with large cones, wide radial petals, and bears many blooms. The wilder looking pale purple coneflower has fewer flowers with drooping lavender-pink petals and slender leaves. But, it has an elegant, untamed look that is appealing in mixed plantings.

Blazing star

Blazing star (Liatris spicata, Zones 3-11) is a bold bloomer with many tall (3 to 5 foot) spikes of fuzzy purple flowers that are prettiest in midsummer. Hummingbirds, bees, and butterflies line the purple wands when they are in full bloom. When not in bloom, the plants have neat clumps of grassy foliage. Site blazing star in a spot with full sun and average to moist soil, and it will grow beautifully.

Yellow coneflowers

The numerous tall, thin stems of yellow coneflower (Ratibida pinnata, Zones 3-9) can reach up to 4 feet (sometimes more). Its golden daisies are visited by bees and butterflies and have prominent central cones with drooping yellow petals that move in the wind. Plant yellow coneflower in full sun and average soil. Established specimens will tolerate drought. Flowering extends from mid to late summer.

Texas and Southeast wildflowers, scarlet sag and spotted horsemint
Spotted horsemint pairs well with the Texas and Southeast wildflower, scarlet sage (Salvia coccinea). (Image by Jessie Keith)

The unusual, tiered pink flowers of spotted horsemint (Monarda punctata, Zones 3-9) have some of the greatest pollinator power around, especially when it comes to feeding bees. The fragrant plants have a long bloom time that can extend from summer to fall. Well-drained soil and full sun are musts. The plants can reach between 2 to 3 feet, and maintain tidy clumps that do not spread, unlike other popular garden Monarda.

Brown-eyed Susan

Brown-eyed Susan (Rudbeckia triloba, Zones 3-9) is a short-lived perennial known for its drifts of tiny golden daisies with brown eyes that delight the eye from late summer to fall. Ease of growth and a tendency to gently self-sow will ensure it will remain in your garden for years to come. Butterflies and bees are regular visitors to the flowers and finches enjoy eating the mature seeds.

These carefree flowers all grow well together. Plant your favorites in a wild border and watch the summer color, pollinators, and birds light up the garden.

Ten Tips for Beautiful Container Gardens

Ten Tips for Beautiful Container Gardens Featured Image
Good care will keep your potted plants looking pretty.

You have purchased your pot, invested in potting soil, planted up your plants, and your container garden is well underway. In the cool of late spring, as container plants are rooting in, there are few stresses to disrupt your plantings. But, as plants grow and the summer heat ramps up, lots can go wrong. Here are tips for getting it all right.

The first half of successful container planting starts in the planning stages, by choosing the right pots, plants, soil, and fertilizer. The second half is knowing what to do to keep your container gardens looking great. Here are our top ten tips for container care from start to finish.

Pre-Planting Container Garden Tips

Colourful high-fired quality ceramic pots
High-fired, quality ceramic pots hold water well and overwinter better. Lighter-colored pots stay cooler in hot weather.
  1. Choose the right pot – Large containers made of the right materials helps plants grow more happily through summer. Big pots hold more water, provide more root space, and remain cooler to encourage good growth through the hottest summer days. Pots made of water-impermeable materials, such as stone, glazed ceramic, plastic, or resin, hold water better. TerraCotta and porous cement pots wick water away from roots because they are porous, so they are better suited to drought-tolerant plants or succulents. Containers that are light in color are better for sunny plantings because they reflect the heat of the sun. Pots must drain well and have a saucer, internal reservoir, or basin to capture excess water. Those with a self-watering base must have an overflow hole to protect against the possibility of overwatering.

Overstuffed containers, like this metal bowl planter with Calibrachoa, sweet potato vine, Bacopa, and geraniums, look good in early summer but are often overcrowded by midsummer.
  • 3. Choose the right plants and numbers. Will you place your containers on a sunny patio or window box, shaded porch, or bright, windy veranda? Is your summer climate hot and dry or mild and cool? The plants you choose must grow well in their destined location and in your local climate. Gardeners planting for sun must choose heat and drought-tolerant plants (click here for a list of Waterwise container plants), while shade-loving plants such as Begonia, Browallia, Impatiens, Torenia, and ferns are good choices for pots in partial to full shade (click here to learn more about growing Torenia). Consider the final size of each plant when designing containers, and do not overstuff the pots. Crowded plants compete for space, light, water, and nutrients, which causes them stress. Before planting, read about your plant’s needs and space them properly to ensure their best performance.
  • 4. Choose the right fertilizer. Gardeners with little time should choose an all-purpose slow- or continuous-release fertilizer to apply at planting time. Vegetable and fruit containers should be fed with plant food specially formulated for edibles. Water-soluble plant food can give plants an extra boost to encourage renewed growth and flowering midseason–particularly after plants have been trimmed and deadheaded.
Hanging summer annuals
Most summer annuals cannot be planted outdoors until the threat of frost has passed.

Post-Planting Container Garden Tips

Watering plants
Good watering technique is essential to successful container gardening.
  • 6. Know when and how to water. Good watering technique is all about common sense. Most garden flowers like lightly moist soil. If the soil is too wet for too long root rot will occur. If it’s too dry for too long plants will begin to wilt and die. When conditions are sunny, dry, hot, and breezy, plants use and lose more water (drawn up through their roots and lost through their leaves) and need more water. Likewise, when it has been rainy, cool, and still the need for water is reduced. Feel the soil before you water to determine if more is needed. If it is needed, irrigate until it flows from the bottom of the pot to ensure all the roots get moist.
Outdoor plants
Well watered and fertilized plants will look lush and flower and fruit well.
  • 7. Know when to fertilize. Slow- or continuous-release fertilizer formulated for flowers makes feeding easy because applications are needed every few months, depending on the product. Apply at planting time and then as directed. Water-soluble fertilizer will encourage further flowering and growth during the height of summer. Containers also need a boost of water-soluble food after they have been trimmed back in mid- to late-summer. Proven Winners offers both a premium continuous-release and water-soluble fertilizer that we recommend for flower-filled containers.
Trimmed petunias
Many petunias continue looking good and blooming for longer if they are trimmed back later in summer.
  • 8. Know if and when to prune and deadhead plants. To maintain any plant properly, read about its care. Some flowering plants are self-cleaning, such as sweet alyssum, Supertunia petunias, and Profusion Zinnias, while others, such as old-fashioned petunias and dahlias, need to have their old blooms removed to make way for new. Old-fashioned petunias, calibrachoa, and verbenas can become leggy, less productive, or overtake the pot as the summer wanes. Cutting the old stems back can rejuvenate growth and flowering for fall.
Old summer containers with fall elements and flowers
Reviving old summer containers with fall elements will give them a needed seasonal boost.
  • 9. Know if and when to replace seasonal flowers. The pansies and stocks of spring often die back in the heat of summer and need replacement with warm-season summer flowers. Summer annuals that begin to look tired by early fall, like marigolds or traditional petunias, should also be replaced with seasonal pansies, peppers, or ornamental kale to keep containers looking great. (Click here to learn more about container gardening with ornamental peppers.) Don’t be afraid to replace struggling annuals when they start to visually bring a container down.
Winter pot in snow
Be sure that winter pots are crack-resistant.
  • 10. Know how to overwinter pots. Be sure you choose the right pots if you want to overwinter containers outdoors (click here to read about overwintering containers). If your pots contain small shrubs or perennials, place them in a protected spot. Seasonal containers can be placed in a garage, basement, or under a dry porch where they will not become damaged by the freezing and thawing of winter.

Once you have the basics down, monitor your containers, protect them from pests and diseases, give them good care, and they will reward you with season-long beauty.

Pruning Hydrangeas

Pink big leaf hydrangeas
Prune mophead bigleaf hydrangeas in summer just after blooming.

Timing and method are essential when it comes to pruning hydrangeas, and they differ depending on the species being pruned. If done improperly, you may prune off next year’s flower buds or cause your shrubs undue stress. On the other hand, making the right cuts at the right time will help keep them looking great and flowering to perfection.

Good Pruning Technique

The right techniques and tools are key to good pruning. Here are the basics.

The Best Pruning Tools

Sharp loppers, hand pruners, and hand saws
Choose sharp loppers, hand pruners, and hand saws for easy pruning.

For small branch cuts (up to 1 cm thickness), choose a quality set of sharp bypass pruners (avoid anvil pruners, which dull quickly). Bypass pruners are easy to sharpen and long-lasting, if you choose a high-performing brand (I like Felcos). For larger branches (up to 4.5 cm thickness), choose sharp bypass loppers. More powerful pruning tools may be needed for large panicle hydrangeas that become tree-like. For larger cuts, opt for a small, sharp pull-stroke pruning saw to cut through tough branches in no time!

How to Prune

Making the right cuts to branches will facilitate good plant health. Cuts to small branches should be made 2/3 cm from the adjacent stem. Make them at 45-degree angles. Larger branches should be cut flush to the trunk collar. The collar is the ripple of bark that will slowly and protectively grow over the cut. Cuts made above the collar will not heal properly, leaving plants vulnerable to pests and disease.

How Much to Prune

A stem with a 45-degree-angle cut
Make 45-degree-angle cuts 2/3 cm from the adjacent stem. Don’t damage lower buds!

Prune to the desired height, but beware of over-pruning. Refrain from pruning over 1/3 of the top growth, especially in smaller shrubs with well-branched woody top growth. Some species, such as smooth hydrangea (Hydrangea arborescens), are clump-forming with stems that can be harshly pruned back if the clumps are well established and have become overgrown. Others, like panicle hydrangea (Hydrangea paniculata), can become tree-like and require more selective pruning.

When to Prune

Hydrangea pruning time is species-specific. Follow the following guide for the top four garden hydrangeas.

Pruning Bigleaf Hydrangeas

Purple hydrangeas
Mopheads have a rounder more formal growth habit.

Latin Name: Hydrangea macrophylla
Best Time to Prune: These hydrangeas bloom on second-year wood, so the best time to prune is in midsummer, just after they bloom. If you prune in later summer or fall, you will cut off next year’s flower heads. Deadwood is common, especially in spring. Dead or dying stems can be removed at any time of year. Old blooms can also be removed at any time, as long as you just remove the flowers and not the buds that have developed below them.

Blue big leaf hydrangeas
Pruning bigleaf hydrangea in fall will remove next year’s flower buds causing irregular flowering the following year.

How to Prune: These hydrangeas can grow too large or develop ungainly stems that have grown too high — shape plants by cutting wayward or old stems to the ground. Stems can also be trimmed to the desired height, depending on the density of the overall shrub. Refrain from shearing bigleaf hydrangeas if you want to maintain a more naturalistic, appealing appearance.
Comments: Bigleaf hydrangeas can have either lacecap (Hydrangea macrophylla var. normalis) or mophead flower clusters. Lacecaps have a looser more naturalistic horizontal growth habit and should be pruned less formally. Mopheads tend to have a rounder habit better suited to uniform pruning. In northern zones above USDA Hardiness Zone 6, these shrubs may die to the ground, so they will never flower. Protecting the crowns with Fafard Premium Natural and Organic Compost and straw can help protect their flowering stems from the winter cold.

Lacecaps
Lacecaps have a more naturalistic habit and require selective pruning.

Pruning Oakleaf Hydrangeas

Standard oak leaf hydrangeas
Standard oakleaf hydrangeas are tall, broad shrubs.

Latin Name: Hydrangea quercifolia
Best Time to Prune: Oakleaf hydrangeas also bloom on second-year wood and should be pruned just after blooming in midsummer. Once shrubs have leafed out in spring, identify and remove any dead wood from the previous year.
How to Prune: Some compact oakleaf hydrangeas have rounder, tidier habits but most reach 8-feet in height and develop a broad, naturalistic habit. Remove overgrown or crossing branches. If they overgrow an area, shrubs can be hard-pruned back by half in midsummer. Just be sure to leave plenty of green leafy branches for strong growth, and keep newly pruned shrubs irrigated through dry summer days to encourage new growth and bud set.
Comments: The pretty flower panicles of oakleaf hydrangea dry nicely and look good in winter gardens. Remove the old blooms in late winter to keep shrubs looking fresh in spring.

Dry flowerhead of oak leaf hydrangea
Keep the dry flowerheads of oakleaf hydrangea on plants for winter interest.

Pruning Panicle Hydrangeas

Panicle hydrangeas
Panicle hydrangeas are hardy and best pruned in late winter or early spring.

Latin Name: Hydrangea paniculata
Best Time to Prune: These tall, hardy hydrangeas bloom on new wood, so the best time to prune is in late winter or early spring. Remove ungainly or crossing branches and dead wood at this time. Refrain from summer pruning, and avoid removing more than 1/3 of the top growth at pruning time.
How to Prune: Panicle hydrangeas are variable shrubs that tend to be tall (8-15 feet) and bushy or tree-like, but some cultivars are compact for small-space gardens. Selectively prune bushy varieties, cutting tall branches to the trunk or base of the plant. Cut the large branches of tree-like varieties to the trunk, making sure cuts are flush to the collar.
Comments: These shrubs revive quickly from pruning. Tree-form plants may develop suckers from the base of the trunk. Keep these pruned off to maintain a single trunk. The dry blooms of panicle hydrangea also look good through winter but should be removed in spring.

Pruning Smooth Hydrangea

Incrediball™ Hydrangeas
Large-headed smooth hydrangeas, like Incrediball™, should be pruned to 1/3 height in late winter. (Image thanks to Proven Winners)

Latin Name: Hydrangea arborescens
Best Time to Prune: These easy-to-grow hydrangeas also bloom on new wood and are best pruned in late winter or early spring. They respond well to harsh pruning and can even be pruned to the ground if they outgrow a space. By late spring, they will have grown back with vigor. Refrain from summer pruning.
How to Prune: Pruned these bushy shrubs uniformly to keep their habit rounded. Large-headed varieties, like Incrediball™, are top-heavy and appreciate regular pruning to 1/3 height to keep stems shorter and sturdier. Refrain from pruning large-headed varieties to the ground.
Comments: The bushy dry flower heads look great in winter but should be removed by spring. These hydrangea root very easily from cuttings. Take any pruned branches, dip them in rooting hormone, stick them in the ground, and keep them evenly moist. They will root in no time!

Creative Upcycled Planting Containers

Old boots as strawberry planters

If gardening is the great equalizer, enabling people of all ages and conditions to grow food, flowers, herbs and other plants; then container gardening is a super equalizer.  Making a “portable garden” means that you don’t need to own land, large tools or even significant space.  And, you don’t have to buy fancy containers to make your plants happy; just “upcycle” something you already have.  The only limits are your imagination and foraging abilities.

Upcycled planting containers make gardening more fun, and they cost nothing. All you need, in fact, is something that holds soil, good potting mix, seeds or plants, sunshine, water, and you have an instant container.  Plant some zinnias in an old dishpan or grow a mess of tomatoes in a repurposed bathtub.  One restaurant reuses commercial-size olive oil cans to house billowing basil plants whose leaves are ultimately harvested and used in various dishes.  Irish gardener/garden writer Helen Dillon uses dustbins—trash cans—to hold plants in her Dublin garden.  Spackle buckets work well, and more than one gardener has pressed an old pair of boots into service as a sturdy container.  The list of recycling opportunities is endless.  In fact, almost anything that will hold soil can be converted to a planter.  People have been recycling old tires and wine barrels to make planters/raised beds for decades.

Upcycled Container Rules

An old sink gets painted and planted into a fun container garden.

There are only a few rules when it comes to recycled containers.  The first is fitting the container to the plant.  A large hibiscus might need the ample space provided by an old wicker laundry basket, while a small herb plant or a succulent can grow well in a cut-off plastic detergent bottle.  When choosing a container to recycle, think about the amount of space the chosen plant might take up if it were in a garden bed.  Make sure the container is deep enough to accommodate the plant’s root system and as wide as the plant’s mature diameter.  Plant tags should provide you with this information.

The recycled container should be clean, since residue from its original contents might be harmful to plants.  A thorough cleaning with a 10% (1:10) solution of household bleach and water, plus a good rinse should be fine for most would-be planters.

Container Care

A weathered trough gets a facelift when filled with beautiful mixed bedding plants.

Container-grown plants also have some specialized nutritional, water, and drainage needs.  Make sure your repurposed containers have drainage holes at the bottom.  If making holes is impossible, fill the bottom quarter of the container with coarse pebbles topped by a layer of charcoal (available in garden centers).  Provide good nutrition from the beginning by investing in high-quality potting media, like Fafard® Ultra Potting Mix with Extended Feed or Fafard® Ultra Container Mix with Extended Feed.
Pay attention to your chosen plants’ light requirements and position the containers accordingly.  Remember that “full sun” means six or more hours per day of direct sunlight, and even plants labeled as “good for shade” need a continuous supply of indirect or filtered light.

Overwatering is the number one cause of container-grown plant death.  Check plant tags or internet resources for water requirements.  Many plants only need water when the soil is dry an inch or two below the surface, but some, like primroses or hydrangeas, prefer evenly moist soil at all times, especially when weather is hot and dry.  Plants that are outdoors during drought periods may need water every day and should be checked frequently.

Check Recycling Day

Rusted cans with plantsClever gardener/recyclers are always on the lookout for potential planters.  If your town has a “bulk pick-up day”, when larger discarded items are picked up for disposal, the perfect plant container may be waiting on a curb in your neighborhood.  Check your garage and attic.  A forgotten corner may harbor a perfect plant container.  The supermarket is also full of future plant pots, especially if you buy items like oil, condiments or canned goods in large sizes.  Look for promising shapes and sizes first, as many recyclable containers can be painted or embellished to suit your indoor or outdoor décor.
Most of all, have fun.  The perfect recycled planter is probably closer than you think!

“Cannatainers” or Cannas for Container Gardening

Cannas emerge from dormancy and hit the horticultural market in late winter and spring, so now is the time to get the show started. Numerous varieties are available from on line and local nurseries, either as potted plants or as bare-root rhizomes (the technical name for the thickened underground stems that give rise to all that splendiferous summer growth).
Fafard Professional Potting Mix pack

Newly purchased plants should be grown indoors in a suitable potting mix until danger of frost has passed, such as Fafard Professional Potting Mix.  Ten- to twelve-inch plastic pots and a two-inch planting depth work well for this initial, indoor growth phase.  For their outdoor, summer home, cannas need containers of a grander and more massive order planted in a water-holding mix, such as Fafard Ultra Outdoor Planting Mix.  An 18-inch-plus clay or ceramic pot (or something in the way of a cast iron urn) is ideal.  Large wooden or terra cotta planters also work well.  Simply knock the plants out of their temporary, indoor containers and place them at the same depth in their outdoor quarters.  Then stand back and watch the fireworks happen (making sure to water liberally and fertilize regularly through summer).

Outdoor gardenAlthough spectacular on their own, containerized cannas make an even more extravagant statement if combined with other heat-loving plants.  For example, the flowers and foliage of gold- and red-hued Coleus provide a striking foil for the sunset foliar tones of Canna ‘Phaison’ (right).  The possibilities are practically limitless, given cannas’ wide range of floral and foliage colors.
When choosing cannas for container gardening, the sky’s the limit. For a lavish summer display on a less colossal scale, use a “dwarf” canna cultivar such as ‘Pink Sunset’, which offers dazzlingly variegated leaves and soft pink flowers on 3-foot (rather than the usual 5- to 10-foot) plants.

Or you can go the other direction and opt for something outrageously gargantuan such as the banana canna, ‘Musaefolia’, a Victorian-age behemoth that towers to 14 feet.  A bathtub of a container (and lots of water) is recommended.

Colourful flowers in black potsCannas slow their pace in fall, requiring reduced water as they gradually die back to their rhizomes.  Dormant plants can be moved indoors, pot and all, for the winter, or the rhizomes can be lifted and stored in paper bags in a well-ventilated location.  Either way, cool temperatures (below 60 degrees F) are best for storage.
In early spring, move containerized cannas to a warmer niche and water sparingly until growth resumes.  Split overwintered bare-root rhizomes into divisions of 3 or more “eyes” (the red, swollen growth points spaced along the rhizomes), and plant them in containers (as described above).   And start planning this year’s summer spectacular.

The Best Vegetables to Grow with Your Kids

The Best Vegetables to Grow with Your Kids Featured Image
The author’s daughter with a pumpkin she grew.

I remember the first time I pulled a carrot from the ground as a child. It was like magic. A simple carrot became a hidden golden-orange gem in the Earth that I could pull and eat! I’d wander the garden, plucking a cherry tomato here, a lettuce leaf there, or snapping off a bean to nibble. It was enjoyable, and I learned to love vegetables in the process. This is why I grow delicious, interesting vegetables with my own children. I’m spreading the garden fun and veggie appreciation.

There were two things I cared about with vegetables as a child: 1. Is it fun to eat? 2. Is it fun to harvest? These are the criteria used for this list. As an added bonus for parents, these vegetables are also easy to grow

Fun Vegetables to Eat and Pick

Cherry tomatoes

Cherry Tomatoes:  There are so many cool cherry tomatoes to try now, and the smaller, sweeter, and more colorful, the better. I recommend ‘Minibel’, which produces sweet red tomatoes on tiny plants, ‘Sun Gold’, which produces loads of super sweet, golden-orange cherry tomatoes, the unusual ‘Blue Cream Berries’ with its pale yellow and blue fruits, and the classic ‘Sweet Million’ which literally produces hundreds of sweet red cherry tomatoes on large vines. Kids also love super tiny ‘Sweet Pea‘ currant tomatoes and ‘Gold Rush’ currant tomatoes, which literally pop with flavor in the mouth. Caging your plants makes harvesting easier—especially for little ones

French Bush Beans

French Bush Beans: My children love French haricot vert bush beans because they are super thin, stringless, and sweet. The best varieties for kids are produced on small, bushy plants. Try the classic green ‘Rolande’ or the golden yellow ‘Pauldor’

Asian Long Beans: These beans look like spaghetti noodles! They are vining, so trellising is required, but they love hot summer weather, and kids love to pick and eat them. ‘Thai Red-Seeded’ is a great Asian long bean for kids because it grows so well, and the super long beans double as green hair or green bean rope.

Beit Alpha Cucumbers

Beit Alpha Cucumbers: These crisp, sweet cucumbers are skinless, practically seedless, and taste great right from the vine. Bring a little water for rinsing, and a little ranch dressing for dipping, and they have an instant garden snack. The new AAS-Winning variety ‘Diva’ is my favorite because it is disease resistant and produces lots of cucumbers.

Miniature Carrots: Mini carrots are easier for kids to pull from the ground, so they get all the fun with no root breakage. Tiny round ‘Romeo’ carrots and the small conical ‘Short Stuff’ are great selections for a kid’s vegetable garden. Both also grow well in containers

Yum Yum Mini Bell Peppers: The name says it all! These yummy, sweet, mini bell peppers look like Christmas lights and come in shades of red, yellow, and orange! The peppers are high in vitamin C and fun to pick. Just be sure to plant your Yum Yum mini bell peppers away from any hot peppers you may be growing

Small Pumpkins: Kids love to harvest and decorate their very own pumpkins in fall! The little guys, like ‘Baby Bear‘ and ‘Baby Pam‘ are just the right size for kids. Extras can be processed to make Thanksgiving pumpkin pies. Be sure to give the vines plenty of sun and space and you will be rewarded with lots of fall pumpkins

Strawberry Popcorn: Kids can believe these cute, deep red ears actually pop up to make tasty popcorn! Strawberry popcorn is produced on smaller 4-foot plants and the ears are small too. They are decorative when dry and can be popped up in winter as a happy reminder of warmer summer days.

Growing Your Vegetables

Organic gardening is a must, especially when growing vegetables for children. Successful vegetables start with good bed prep and summer-long care. Choose a sunny spot, work up your garden soil, and add a healthy amount of Fafard Premium Natural & Organic Compost and Fafard Garden Manure Blend before planting. Keep your vegetable watered and watch them do their summer magic

When children grow their own vegetables, they eat their vegetables. They look forward to the harvest and enjoy preparing what they have picked. Let them help snap the beans for a salad or clean the carrots before trimming and peeling them for snacking. There’s no better way to enjoy time with your kids while instilling good lifelong habits in the process.

How to Create Miniature Water Lily Pots

The white pygmy water lily is tiny and perfect for container culture.

Nothing is more pleasing and cool in summer than a water garden filled with water lilies. Most gardeners don’t consider growing these beautiful aquatic flowers because they lack the desire or space for a pond, but ponds are not needed if you grow small. Watertight, spacious troughs or pots can be converted into tiny water gardens for miniature water lilies. If you have a partially sunny patio, deck, or garden space that can take the weight of a water-filled pot, you are set!

Choosing a Container

Pot with miniature water lilies
Any deep, spacious, water-tight pot will hold miniature water lilies.

Water lily pots have to be large and spacious, so start by choosing a container that’s at least 15-18 inches deep and 24-40 inches wide. This will give you enough space for your lilies. Pots must be watertight. Specialty “no hole” pots designed for aquascaping are sold, but you can also line large pots with pond liner, which is often a cheaper option. Simply cut the liner to a size that will fit in your pot and place it snugly along the inner lip of the pot. It helps to apply a strong, non-toxic adhesive along the edge to keep it in place.

Choosing Miniature Waterlilies

Yellow water lily 'Helvola'
The yellow water lily ‘Helvola’ is a classic compact variety that grows beautifully in containers.

True miniature water lilies are so tiny that some have flowers the size of a quarter. Many are pygmy waterlily (Nymphaea tetragona) variants, which are very hardy—surviving winters as cold as USDA Hardiness Zones 4-11 with good protection. They come in a suite of colors that include ivory, pale yellow, pink, and red. The best for home gardens are easy to find online or in specialty stores.

One of the tiniest miniatures is the white pygmy water lily (Nymphaea tetragona ‘Alba’). The hardy plants reach 18 to 24 inches across and sport tiny white flowers that float alongside teensie lily pads. Another beautiful white-flowered variety with much bigger, tulip-shaped flowers but a small growth habit is ‘Hermine’.

The peach-pink-flowered ‘Berit Strawn’ (Nymphaea ‘Berit Strawn’) has larger flowers (3 to 4 inches across) and pads of deep green with some reddish mottling. The little plant is perfect for container growing, very hardy, and will bloom nonstop from early summer to fall. Plants will spread between 24 and 30 inches.

'Hermine' water lilies
‘Hermine’ is a stunning, white-flowered miniature water lily.

One of the smallest red-flowered miniatures is ‘Perry Baby Red’ (Nymphaea ‘Perry Baby Red’). Its rosy-red flowers compliment dark green pads. Plants spread 12 to 36 inches across.

An older, classic mini water lily is the hardy ‘Indiana’ (Nymphaea ‘Indiana’). Its tricolored, 2- to 3-inch flowers are in shades of rose-red, yellow, and orange. The diminutive plants have a spread of 12 to 28 inches across and small green pads with reddish spots.

One of the best yellow-flowered water lilies is the cheerful ‘Yellow Pygmy’ (Nymphaea ‘Helvola’). Its flowers are only 2 inches, but they are bright and pretty. Plants reach 18 to 36 inches across.

There are lots of great sources for miniature water lilies. Lilypons and Texas Water Lilies are good sources that offer quality selections.

Planting Waterlilies

Water lilies grow from fleshy tubers that must be grounded in smaller pots and sunk below the surface of your water container. Choose a wide, shallow pot that will provide plenty of space. Planting depth can be 10 to 24 inches from the water surface. Pots should be placed where they can get 6 hours of sun per day or more. These planters can only be prepared after the threat of frost has passed.

Line the pots with porous but tight-knit plastic burlap bag. Fill it with a 3:1 mixture of heavy loam and Fafard Premium Natural & Organic Compost. Add just enough to fill the pot bottom and hold the waterlily tuber. The compost and soil must be well combined before planting. Finally, add a teaspoon of a slow-release, all-purpose fertilizer to the mix. Overfertilization can cause algal bloom, so don’t add more during the season.

Cut a small hole in the bag and sink the tuber into the soil, so the top of the plant meets the soil line. Once it is planted, line the top 2 inches of the pot with pea gravel to help keep the soil and plant in place. Place a 1- to 2-inch thick rock along one side of the pot, so it sits at a slight angle. Doing this helps with gas exchange for healthy root growth. Small- to medium-sized water pots don’t need aeration filters.

Gently fill the pot with clean tap water to a depth a couple of inches below the lip of the pot. Soon the plant will put forth fresh pads followed by flowers.

Maintaining Potted Waterlilies

Clean, fresh water is important to the health of potted water lilies.

Keeping the water clean in your water lily pot is essential. Remove any debris that falls in the water, and cut old leaves from your water lilies. Refresh the water regularly as it recedes.

Water-filled containers cannot be allowed to freeze in winter, even if your water lily is hardy. They are too exposed above ground and freezing and thawing will cause the containers to crack. The best course of action is to drain the container before the first freeze of the season, remove the lily from the pot (being sure to cut back the leaves), and store it in a water-filled bucket in a cool, dark place through winter. Water lily tubers should be divided every two to three years.

These cool, impressive containers will brighten any summer garden spot. If you want the tranquil beauty of a pond without all the work and hassle, plant a water lily pot this season.

Late-Summer Flower Garden Renewal

Hibiscus 'Disco Belle Pink'
Hibiscus ‘Disco Belle Pink’ is a reliable late-summer bloomer.

In August, high summer is well established.  Drought and hot weather have generally taken their toll on gardens and gardeners, both of which may look and feel a little tired.  Caught between the tail end of the daylilies and the beginning of the asters, the holes in the borders begin to fill with crabgrass and other evil weedy entities.  We all want our plantings to look lovely, but when it is 95 degrees F in the shade the usual urge to dig in the dirt or refresh the containers is tempered by a natural reluctance to lift more than two fingers.

What to do?  A bit of inspiration won’t cool things off, but it may make the garden look better.  The following are a few easy-to-grow and easy-to-love plants that are in bloom now and can improve the look of late summer beds and pots.

Cheap Annuals

Most garden centers still have a few summer annuals left, generally lurking on the sale tables or grouped into mixed container arrays.  The garden centers want them out, and as long as the plants are still relatively pretty and healthy, you can use them to refresh your garden plantings.  A few of these plants will be goners, but many simply need liberation from the pots that have housed them since spring, a bit of pruning or pinching back, a judicious amount of liquid plant food, and a fair amount of water. Leggy petunias, sad impatiens, and seemingly spent snapdragons usually take to tender loving care and will respond by bouncing back and blooming nicely until frost.

Go to the garden center early in the morning, late in the afternoon, or on a cloudy day. Bring your bargain plants home, apply the restorative treatments right away, and pop them in place in the cool of the evening.  Don’t be afraid to disaggregate mixed containers and install the individual plants wherever you need them.  Mixed containers are all marriages of merchandising convenience anyway.

Now and Later Perennials

When you take your cool-of-the-day trip to the garden center, keep an eye out for perennial species and varieties that are in bloom now.  Black-eyed Susans (Rudbeckia spp.) and their relatives, the ever-increasing coneflower clan (Echinacea spp.), are in bloom at nurseries all over the country and will multi-task when you get them home, supplying color now and the promise of the same thing next year at this time.  Their daisy-family kin, the tickseeds (Coreopsis spp.) are also in bloom and should produce at least one more flush before frost if you deadhead them at planting time. Look for reliable, tried-and-true varieties found at almost any nursery, such as the classic Coreopsis ‘Moonbeam’ with its vigorous habit and numerous pale-yellow flowers, and Echinacea purpurea ‘Magnus’ with its large pink flowers with dark cones.

Less formal perennials of late summer include Joe Pye-Weed (Eupatorium purpureum, 5-7′) a late summer star, especially for informal, cottage-type gardens or native borders.  This lofty perennial may not fit all garden sizes, so those with smaller borders may consider planting the somewhat shorter Joe Pye-weed, Eupatorium dubium ‘Little Joe’, which reaches only 3-4′ in height. All Joe Pye-weeds are stellar butterfly plants. Wand flowers (Gaura spp.) are also great late-summer butterfly plants that are airy, beautiful and generally drought tolerant.  The delicate variety ‘Pink Fountain’ is one of several pink-flowered forms that shine at this time of year. Use them in mid-border or medium-size pots for stature and delicacy.

Magnificent Mallows

Late summer is prime time for striking members of the mallow family, including shrubs like rose of Sharon (Hibiscus syriacus) and bodacious perennial bloomers like hardy, native, swamp mallow (Hibiscus moscheutos).  Both are widely available at nurseries and garden centers and bear large, prominent hollyhock-like flowers combined with attractive foliage.  Plugging a few mallows into a mostly fallow flower garden will add instant impact.  A container full of ‘Disco Belle Pink’ swamp mallow, with its enormous pink flowers, or large, red-flowered ‘Heartthrob’, will light up even the most uninspired space.
The large, bushy swamp mallow requires full to partial sun and can be grown either in-ground or in large containers.  If you try growing one in a container, start with a high-quality, moisture-retentive potting medium, like Fafard® Ultra Container Mix With Extended Feed.  Late summer mallows, especially the swamp type, are moisture lovers and the moisture-holding crystals in the Fafard mix will keep the plants happy, even during the inevitable dry spells.

Planting at the day’s coolest or cloudiest times will help new plants and heat-depleted gardeners stave off stress.  Be sure to water in plants as they are installed and the water daily, if necessary, until the weather starts to cool off.  After that, relax.  Your garden will have inspired the neighbors, even during summer’s dog days, and you will be ready to start thinking about all those bulbs that you ordered while sitting in front of the AC in August.
