How to Grow Grand Rapids
Lactuca sativa 'Grand Rapids'
Grand Rapids lettuce is a popular cool-season variety prized for its buttery texture and slow bolting habit. Gardeners favor this heirloom choice because it maintains crisp leaves longer than many other types while tolerating light frost well.

🌾 Sow directly in the garden — Grand Rapids is not usually started indoors.
Grand Rapids lettuce is best direct-sown into the garden rather than transplanted, though seedlings can be moved carefully if necessary.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.5 before sowing seeds directly outdoors or starting them indoors. As a cool-season crop, plant the seeds 2 to 6 weeks before your last expected spring frost. Press seeds gently into the soil at a depth of about half an inch. Germination typically occurs within 5 to 10 days under proper conditions.
Space plants 6 to 8 inches apart to ensure good air circulation and steady growth. While this variety does not require trellising, keep the soil consistently moist with 0.75 to 1 inch of water per week. Apply a light layer of mulch around the base to retain moisture and suppress weeds without smothering the shallow roots.
Watch for aphids, slugs, snails, and cabbage loopers; use row covers or hand-picking to manage them early. Prevent downy mildew and bottom rot by ensuring good airflow and avoiding overhead watering. Harvest outer leaves when plants reach maturity in 45 to 55 days after sowing for continuous cutting.
