🌾 Sow directly in the garden — Loose Leaf Green Grand Rapids is not usually started indoors.
Direct sow seeds outdoors or start indoors to transplant seedlings gently into the garden once they have developed true leaves and the soil has warmed slightly before the last frost.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.0. Sow seeds directly outdoors or start indoors 4 to 6 weeks before your last spring frost date. Press seeds gently into the surface since they require light for germination, which typically occurs within 7 to 14 days. Keep the seedbed consistently moist during this critical early stage.
Space plants 6 to 8 inches apart in rows to ensure proper airflow and leaf development. While lettuce does not need support or trellising, maintain consistent moisture by providing about 1 inch of water weekly. Apply a light layer of mulch around the base to retain soil moisture and suppress weeds without smothering the shallow roots.
Monitor for aphids, flea beetles, slugs, and rabbits; use row covers or hand-picking to manage these pests effectively. Watch for downy mildew, lettuce drop, and bottom rot by ensuring good air circulation and avoiding overhead watering. Harvest outer leaves as needed starting at 45 to 55 days after sowing when heads are firm.
