How to Grow Little Gem
Lactuca sativa
Little Gem lettuce is a beloved heirloom cool-season crop prized for its compact size and sweet flavor. Gardeners grow it in gardens or containers because it tolerates light frost and produces crisp heads quickly. Its small footprint makes it ideal for tight spaces while delivering high yields per square foot.

🌾 Sow directly in the garden — Little Gem is not usually started indoors.
Little Gem is best direct-sown into the garden rather than transplanted, as seedlings transplant poorly and may suffer shock.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.0 to encourage healthy root development. As a cool-season crop, sow seeds directly outdoors 2 to 6 weeks before the last spring frost or start indoors during this window. Press seeds gently into the soil at a depth of about one-quarter inch. Expect germination to occur within 7 to 14 days under consistent moisture.
Space plants 6 to 8 inches apart to ensure proper air circulation and head formation. While Little Gem does not require trellising, keep the soil consistently moist with about an inch of water weekly. Apply a light layer of mulch around the base to retain moisture and suppress weeds. Feed lightly if growth slows, though this variety often thrives on initial soil nutrients.
Watch for aphids, slugs, cutworms, and flea beetles; use row covers or hand-pick pests early. Prevent downy mildew, lettuce drop, and tip burn by ensuring good airflow and avoiding overhead watering. Harvest outer leaves when young or wait until the plant reaches 40 days from sowing for a full head. Cut heads at the base just before they bolt to enjoy peak sweetness.
