Quick Answer

Sow lettuce seeds ¼" deep in cool weather (40-75°F). Thin to 6-12" apart depending on variety. Harvest leaf lettuce in 30 days by picking outer leaves. Head lettuce takes 50-75 days. Lettuce bolts in heat — grow it in spring and fall.

Lettuce Types

Start with loose leaf. It's the most forgiving, fastest to harvest, and regrows after cutting.

When to Plant

Lettuce is a cool-season crop. It grows best between 45-75°F.

Key rule: Plant 4-6 weeks before your last spring frost, or 6-8 weeks before your first fall frost.

Succession planting: Sow every 2 weeks for continuous harvest instead of one big crop.

How to Plant

Direct Sow (Easiest)

1. Prepare soil — Loose, rich, well-draining. Mix in compost.
2. Sow seeds — Scatter on surface or plant ¼" deep. Seeds need light to germinate.
3. Thin seedlings — When 2" tall, thin to proper spacing.
4. Water gently — Keep soil consistently moist. Don't blast seeds away.

Transplanting

Start seeds indoors 4-6 weeks before planting out. Lettuce transplants well.

Container Growing

Lettuce thrives in containers. Use at least 6" deep pots with drainage. Perfect for patios and balconies.

Growing Conditions

Partial shade is fine. Lettuce is one of the few vegetables that actually prefers some shade, especially in warmer zones.

Care Tips

Watering

• Keep soil evenly moist. Lettuce is 95% water — it needs consistent moisture.
• Water in the morning to reduce disease risk.
• Mulch to retain moisture and keep roots cool.

Feeding

• Lettuce is a light feeder. Compost at planting is usually enough.
• If leaves look pale, side-dress with compost or diluted fish emulsion.

Weeding

• Lettuce has shallow roots. Hand-pull weeds carefully.
• Mulch suppresses weeds and keeps soil cool.

Harvesting

Leaf Lettuce (Cut-and-Come-Again)

• Pick outer leaves when 4-6" long. Leave the center to keep growing.
• One planting can produce 3-4 harvests over several weeks.
• Cut 1" above soil level for a full second crop.

Head Lettuce

• Harvest when heads feel firm.
• Cut at the base with a sharp knife.
• Harvest in the morning for crispest leaves.

Signs It's Time to Harvest

• Leaves are full-sized for the variety
• Before any center stalk starts to elongate (bolting)

Dealing with Bolting

Bolting = lettuce sends up a flower stalk and leaves turn bitter. Caused by:

• Temperatures above 80°F
• Long days (14+ hours of daylight)
• Stress (inconsistent watering)

How to Delay Bolting

1. Shade cloth — 30-50% shade cloth extends the season by 2-3 weeks.
2. Mulch — Keeps roots cool.
3. Heat-tolerant varieties — Jericho, Muir, Nevada, Summer Crisp.
4. Succession plant — Always have young plants coming. Young lettuce tolerates heat better.
5. Afternoon shade — Plant on the east side of taller crops.

Common Problems
