🏠 Start indoors 3 weeks before your last spring frost, then move the seedlings outside.
You can start seeds indoors three weeks before the last frost and transplant seedlings outdoors once they are sturdy enough to handle cooler temperatures.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.0 for optimal growth. As a cool-season crop, sow seeds directly outdoors 2 to 6 weeks before your last expected frost date, as they tolerate light frosts well. Press seeds gently into the soil at a depth of about half an inch. Expect germination within 7 to 10 days under consistent moisture.
Space seedlings 4 to 6 inches apart to ensure proper air circulation and head formation. While lettuce does not require trellising, keep the soil consistently moist with about one inch of water per week. Apply a light layer of mulch around the base to retain moisture and suppress weeds, but avoid covering the leaves to prevent rot.
Watch for aphids, flea beetles, slugs, and leaf miners; use row covers or hand-pick pests early. Prevent downy mildew and bacterial soft rot by ensuring good airflow and avoiding overhead watering. Harvest outer leaves when the plant is mature, typically around 47 days after sowing, or cut the whole head for a full yield.
