I sowed my rocket and lamb’s lettuce bare in mid-August just to get them in early: forty-eight hours later, the first leaves told me it was already too late
Sowing rocket and lamb’s lettuce in mid-August feels productive but often backfires within two days. The culprit isn’t bad luck or poor seeds—it’s soil temperature. These cool-season crops have strict germination windows that mid-August heat violates, triggering dormancy or weak, stressed seedlings that bolt before producing usable leaves.
