Upland Cress

Sow indoors any time of year, pressing seeds into seed-starting mix at a depth of 1/4 inch. Keep soil temperature between 45 and 65 degrees Fahrenheit for optimal germination. For a continuous supply of tender greens, sow fresh seeds every 7 to 14 days. Transplanting is recommended; sow indoors and move seedlings outdoors once established.

Transplant seedlings outdoors after they develop their first true leaves. Harden off by gradually exposing seedlings to outdoor conditions over 7 to 10 days. Plant in full sun in well-draining soil with pH 6.5 to 7.5. Space plants 4 to 6 inches apart if growing for mature plants, though the variety's low stature means spacing is more forgiving than larger greens.

Direct sowing outdoors is possible but less common. Sow seeds directly into prepared soil at 1/4 inch depth in spring or fall when temperatures are between 45 and 65 degrees Fahrenheit. Thin seedlings as needed, though thinning is not strictly required for this variety.

Begin harvesting baby leaves 50 to 59 days after sowing, or earlier if you prefer ultra-tender microgreens. Pinch off the outer leaves or cut the entire plant 1 to 2 inches above soil level, and it will regrow for a second or third harvest. For the most delicate flavor, pick leaves in the early morning after dew has dried. Don't overlook the shoots and unopened flower buds, which are equally edible and add textural variety to your plate. The plant's low growth habit makes hand-harvesting easy; simply work your way around the plant rather than stripping it bare in one pass.
