When to Plant Microgreens in Connecticut
Growing Microgreens in Connecticut
Zone 6 gardeners hit the sweet spot for microgreen cultivation, with moderate temperatures and a substantial 180-day growing season that runs from mid-April through mid-October. The relatively predictable frost dates give you excellent planning flexibility, though the key challenge lies in managing the temperature swings that can stress young seedlings – particularly during those unpredictable late spring cold snaps and early fall temperature drops that Zone 6 is notorious for. Your success hinges on choosing varieties that can handle these fluctuations while still delivering the tender, flavorful harvests microgreens are prized for.
The varieties I've selected for Zone 6 specifically excel in temperatures between 60-75°F and can tolerate the occasional dip into the 50s without bolting or becoming bitter. Fast-growing options like radish and arugula microgreens let you squeeze in multiple harvests even if you get a late start after frost, while hardier choices like kale and mustard microgreens can push the season boundaries when grown in protected environments. These picks also consider Zone 6's moderate humidity levels – avoiding varieties prone to damping-off while maximizing flavor development in your climate's natural growing conditions.

Variety Details

Alfalfa Microgreens
Commonly used to add flavor and texture to salads and sandwiches. One tablespoon of seed yields approx. 2-3 cups of sprouts. All of Johnny's high-germination sprouting seeds have tested negative for the presence of E. coli 0157 and Salmonella. USDA Certified Organic.

Amaranth Microgreens
Round to heart-shaped leaves are medium-green overlaid with burgundy red. Striking color on the undersides of the leaves. Cutting the top of the plant yields beautiful, multicolored rosettes that can be added to mixes. Comparable to spinach in flavor. Often used in soups.

Arugula Microgreens
Purple stems and dark-green leaves. Based on our yield trial, we recommend seeding 10 gm per tray at approx. 3 flats per oz of seed. Avg. days to maturity was 14 days when harvested at the first true leaf (as opposed to cotyledon) stage. Also available in organic seed.

Basil Microgreens
Large 2-3" long, turned-down leaves. This stunning basil is nearly black in color. Purple flowers and red leaves make an attractive garnish. Ht. 16-20".Edible Flowers: Use the flowers in any recipe that calls for basil, or to garnish drinks, salads, soups, pasta, and desserts. Flavor is of intense basil.

Buckwheat Microgreens
Buckwheat is widely grown as a grain crop, bee pasture, soil improving cover crop and as wildlife cover. It is a warm season grain which grows rapidly during the summer and several crops per year may be had with proper management. This rapid and dense growth chokes out weeds and is used in crop-free fields in rotation with vegetables. Buckwheat is often grown to attract beneficial insects and as pasture for honey bees. Sow in late May through July and till in about a month later, when flowering has begun. For grain harvest, sow 3 months before fall frost. Harvest after killing frost.

Cabbage Microgreens
Extremely uniform small heads with good wrapper leaves. Inner leaves are tender, crunchy, and have an excellent, sweet, mild cabbage flavor. Perfect for summer salads, slaws, or cooked dishes. In the UK, they are harvested early in the season, before they have fully headed, and sold as "spring greens." Avg. head weight: 1 1/2-2 lb. Also available in organic seed.

Carrot Microgreens
Purple Kisses is very similar to Dara, with 3-5" lacy umbels atop strong, sturdy, upright stems. Flowers in shades of dark purple, pink, and approximately 15% white. Highly productive with 7-15 stems per plant. Long lasting in bouquets. Also known as Queen Anne's lace, ornamental carrot, and wild carrot.

Celery Microgreens
Medium-large, relatively smooth round roots with buff-colored skin. Interiors are white and flavorful and resist pithiness and hollow heart. Also available with NOP-compliant pelleting.

Chia Microgreens
These nutrient-dense microgreens offer a unique growing experience as the seeds become gelatinous when wet, creating their own natural growing medium. Chia microgreens have delicate, tender leaves with a mild, slightly tangy flavor that's completely different from the crunchy seeds. They're packed with omega-3 fatty acids and provide a gourmet touch to salads and smoothies.

Chives Microgreens
Compared to Staro, Purly has a more upright plant habit with a slightly straighter leaf. Edible Flowers: Pull the florets apart and sprinkle on salads, dips, sauces, soups, stir-fries, and pizza. Great as an addition to potato salad. Flavor is of mild, sweet onion.

Cilantro Microgreens
Santo is a slow-bolting selection grown for its leaves. Like the leaves and seeds, the flowers are also edible. NOTE: We test all our cilantro/coriander lots for the presence of Pseudomonas. Attracts Beneficial Insects: if allowed to flower, provides pollen and nectar for beneficial insects such as, bees, hoverflies, and tachinid flies.Edible Flowers: Use them raw because the flavor fades quickly when cooked. Sprinkle to taste on salads, bean dishes, chicken, and spicy Southwestern dishes. Flavor is of mild cilantro.

Clover Microgreens
Once established, white clover can handle foot and tractor traffic better than other clovers. The fibrous root system typically is in the top 8" of soil, although it does have up to a 40" tap root in the first year which dies each fall, leaving a passage for water to percolate through. More heat tolerant than some of the larger clovers, this is a low-growing (to 12") perennial that can be sown into long-season row crops during the season to provide a "living mulch." Sow after first cultivation and rake or cultivate to cover. Also used for green manure, hay, and pasture. Inoculate with Alfalfa/True Clover Inoculant (#7535) for best performance.

Corn Microgreens
7-8" ears with glossy deep yellow kernels. A high percentage of kernels pop producing tender popcorn. 8-9' plants.

Cress Microgreens
Also known as "Curly Cress" or "Peppergrass." Try adding cress to a sandwich or when an extra-spicy bite is needed. Based on our yield trial, we recommend seeding 10.5 gm per tray at approx. 3 flats per oz of seed. Avg. days to maturity was 13 days when harvested at the first true leaf (as opposed to cotyledon) stage. Also available in organic seed.

Dill Microgreens
Early flowering plants produce large blooms, seed umbels, and foliage on long stems, making Bouquet the preferred dill for cut-flower use and pickling. Also an economical, fast-growing choice for baby-leaf production. Edible seeds, flowers, and greens flavor many foods. Popular addition to sauces, salads, and soup. Foliage known as dill weed. Edible Flowers: The flowers are used to garnish potato salad, green salads, and pickles. When broken into florets, they can be mixed into a cheese spread or omelet.Also available in organic seed.

Fennel Microgreens
Vigorous and uniform strain is slow to bolt. Nonbulbing type. Leaves are a nice addition to salads, coleslaws, and dressings.Flavor in fennel develops and intensifies as plants mature. Very young plants (baby-leaf stage) will have a mild flavor, while mature plants (8-12" tall) will have a fuller fennel flavor. Edible Flowers: The florets are used to garnish savory dishes, and pair well with fish, potato, tomato, and beef dishes. Flavor is of sweet anise.USDA Certified Organic.

Fenugreek Microgreens

Zone 6 Growing Tips for Connecticut
Start your microgreen succession planting about two weeks after your average last frost (so early May in most Zone 6 areas), once soil temperatures consistently reach 50°F and nighttime temperatures stay above 45°F. The beauty of microgreens is that you're harvesting in 7-21 days, so you can easily work around weather uncertainty. For spring plantings, focus on cool-season varieties like pea shoots and arugula that won't mind if temperatures dip, then transition to heat-tolerant options like sunflower and basil microgreens as summer approaches.
Your biggest Zone 6 challenge will be managing moisture during the humid summer months – ensure excellent air circulation and avoid overhead watering in July and August to prevent fungal issues. Come September, you can restart cool-season varieties and often continue harvesting well into November with simple season extension techniques like row covers or cold frames. Many Zone 6 growers find that their best microgreen harvests actually come in fall when the moderate temperatures and lower humidity create ideal growing conditions.
