  1. 5 Fast Cool Season Vegetables for Instant Gratification

    Spinach is a very fast-growing spring green, especially when harvested in baby-leaf form.

    “Patience is a virtue,” says the old adage, but sometimes even the most virtuous gardeners long for a little instant gratification.  Succulent tomatoes and winter squash are a great reward for a season of waiting, but not all edible plants require a long growing period.  In the “cool” growing season of early to mid spring and fall, you can have your salad and eat it too—sometimes in as little as 30 days—as long as you choose the right varieties and provide them with a bit of sunny space.  Always check the seed packets of various varieties for specific directions and the approximate number of “days to harvest”.  Quick-growing veggies can generally be harvested in less than 55 days from sowing.  The following is a list of five of the tastiest and most popular “instant gratification” crops.

    Mesclun Mix

    Mesclun mix is very fast growing, especially if harvested as microgreens.

    This widely-marketed greens seed mix usually contains an assortment of early lettuces and other fast greens.  Depending on the seed producer, mesclun is sometimes also labeled “early spring mix” or “mixed baby greens.’  Some vendors offer a variety of mesclun mixes to suit different tastes.  No matter what the mix, the tiny seeds produce a crop of tasty small leaves in about 30 days, which is lightening fast by garden standards.

    Mesclun is easy to grow in containers, raised beds or conventional garden beds.  Sprinkle the seeds over moist soil and do not cover because lettuce seeds need light to germinate.  Water deeply using a gentle spray.  Sprouting should occur relatively quickly.  The young greens can be harvested when the leaves are four to six inches long.  Succession planting every two weeks in spring and fall ensures a continuous crop.

    Relish the Radish

    Radishes are ready to harvest in no time!

    Radishes add a peppery bite to salads, sandwiches or all by themselves with a little sweet butter and salt.  Radish lovers can rejoice in the fact that they are also quick to grow.  For fast growth, select early spring varieties, like ‘Champion’.  Sprinkle seeds over the soil and cover thinly.  When the sprouts reach about two inches tall, thin to three inches apart.  The young radishes should be ready in about 30 days.  The best way to detect readiness is to pull one, wash it and taste it.  As with mesclun, succession sowing will provide you with a consistent radish supply.

    Baby Carrots

    Kids love to harvest baby carrots.

    Veggie lovers know that the “baby carrots” you buy in bags at the supermarket were actually sculpted from regular-size carrots at a processing plant.  In-a-hurry gardeners can have the genuine article—real diminutive carrots—in about 55 days from sowing.  Little carrots are excellent choices for container growing as well.  Pick a small-size carrot variety, like ‘Caracas Hybrid’, and sow thinly in loose soil to which compost has been added.  A product like Fafard® Premium Natural & Organic Compost is perfect for this, providing the carrots with the lightened growing medium they need to produce straight roots. When seedlings emerge, thin to one inch apart.  Water consistently whenever the top of the soil feels dry.  At the 55-day point, or even a little earlier, pull one of the carrots.  If it seems big enough, you are ready for harvest.

    Spinach

    Spinach

    Popeye may have eaten his spinach straight from the can, but he knew that the leafy greens are tasty and exceptionally good for you.  Spinach is also a boon for impatient gardeners.  Like other fast-growing veggies, it is also perfect for container growing, which should be music to the ears of those afflicted with deer, rabbits or other garden varmints.  For container success, pick a smaller spinach variety, like ‘Melody’ or ‘Red Kitten’.  Sow seeds about one inch apart in a planting medium that is pH neutral and enriched with plenty of compost.  When the seedlings emerge, thin to two to three inches apart.  The spinach harvest should be ready in about 40 days, depending on the variety.

    Bok Choy

    Mature bok choy

    Sometimes also known as pak choi, this Asian member of the cabbage family has become increasingly popular for home gardeners, who use the mild-flavored leaves in everything from stir fries to salads.  For speedy results and/or container growing, choose dwarf varieties that can be harvested after about 40 days, when they are less than 10 inches tall.  As with other fast growers, sow seeds about two inches apart, cover with a thin layer of soil and keep uniformly moist.  Dwarf varieties can be thinned to three inches apart.  Harvest the entire head, as you would a cabbage.

    Fast-growing vegetables are a great way to hit the ground running in spring, but most have a tendency to “bolt” as weather warms, flowering and sprouting bitter leaves when summer’s heat sets in.  Save leftover seed for the second cool season in the fall, when you can rejoice in baby greens and radishes all over again.

  2. Growing Cherry Trees

    Sour cherry trees laden with fruit.

    Nothing tastes better than firm, succulent cherries right off the tree – especially if they come from your own back yard!  Thanks to a new generation of hybrid and dwarf cherry trees, home-grown cherries are literally within the reach of more gardeners – in more climatic zones – than ever before.

    As with everything gardening, choosing the right varieties and giving them the right conditions and care are the keys to getting your backyard cherry orchard off to a good start.

    Consider planting your cherries on foot-tall mounds.

    What Cherries Want

    All cherries thrive in full sun and fertile, well-drained, slightly acid soil.  They also favor mild, relatively dry summers and chilly winters (most cherries won’t bear fruit unless they receive several hundred hours of sub-45-degree temperatures).  If you can offer these conditions, as well as a planting site that’s not overly prone to late, bud-damaging frosts, you’re likely to have good luck with all kinds of cherries.

    Start With the Soil

    Nutrient-rich loam is ideal.  If you garden in sand, apply 2 or 3 inches of Fafard Premium Natural & Organic Compost, and till it in before planting.  If heavy clay soil predominates, consider planting your cherries on foot-tall mounds or berms of topsoil amended with compost.  Higher berms (at least 3 feet tall) will also help protect flower buds from spring frost damage.

    Avoid siting cherries in warm microsites (such as the south side of a building) that encourage premature, frost-susceptible bud development.  In areas where heat and humidity are a challenge, maximize air circulation through proper pruning (see below) and generous spacing.

    Pick the Right Cherry

    Sweet ‘Rainier’ cherries require very specific growing conditions.

    As fate would have it, the most popular cherries are also the most persnickety (of course!).  Sweet cherries (Prunus avium) such as the supermarket standbys ‘Bing’ and ‘Rainier’ are good bets only where temperatures stay mainly between 90 and minus 20 degrees  F (sorry, Southern gardeners!).  Because of their chilling requirements, they also do poorly in regions with mild year-round climates.  The few sweet cherry varieties (including ‘Minnie Royal’ and ‘Royal Lee’) with relatively low chilling needs are worth a try in marginal mild-winter areas.  Wherever they’re grown, most sweet cherry varieties require another compatible variety nearby to set fruit (only ‘Stella’ and a few others are self-fruitful).  For a list of varieties that “pollenize” each other, click here.

    ‘Montmorency’ is a classic sour cherry variety.

    Sour cherries (Prunus cerasus) tolerate somewhat more heat, humidity, and cold, making them a safer bet than sweet cherries for regions such as the southern Plains, lower Mid-Atlantic, and upper Midwest and Northeast.  Their self-fruitfulness and relatively compact size also make them a better fit for smaller gardens.  The tart fruits are excellent in pies and preserves, or for eating out of hand.  By far the most popular variety is ‘Montmorency’, but many others are available.

    Even icebox climates such as northern Maine and the upper Great Plains now offer the possibility of fresh-off-the-tree cherries.  Recently introduced hybrids between Prunus cerasus and its shrubby cousin Prunus fruticosa produce flavorful cherries on 6- to 10-foot plants that are hardy to minus 50 degrees F.  Cultivars include ‘Crimson Passion’, ‘Carmine Jewel’, ‘Romeo’, and ‘Juliet’.  All are self-fruitful.

    Choose the Right Sized Tree

    Stark® Gold™ sweet cherry can be purchased on various sized root stock.

    At 20 to 40 feet tall, full-sized sweet- and sour-cherry trees are too large for many home gardens.  They are considerably shorter, however, when grafted on dwarfing “Giselsa” rootstocks recently developed in Germany.  For example, sweet cherry cultivars grown on Gisela 6 understock mature at 60 to 90 percent of the height of full-size trees, and begin fruiting within 3 years of planting.   Gisela-grafted trees also show good hardiness and disease resistance.  Most mail-order suppliers of cherry trees offer a smorgasbord of cultivar/rootstock combinations.

    Caring For Your Cherries

    Whatever the best cherry trees for your place and purposes, they’ll need constant care to thrive.  Apply organic fertilizer and a layer of compost in spring, followed by 1 or 2 inches of bark mulch to keep the soil moist and cool and to inhibit weeds.  Prune out spindly twigs, unproductive branches, water sprouts, and other superfluous growth in midsummer (avoid pruning during rainy or humid spells).  Harvest ripe cherries and collect and discard dropped fruits several times a week, to keep spotted wing fruit flies and other pests at bay.  Rake and remove fallen cherry leaves, which may host disease-causing spores.  Make your yard a haven for beneficial insects by planting species that host them (such as members of the parsley and daisy families).  These and other measures can help keep your cherry trees happy, and your table brimming with fresh cherries.
