When and Where to Plant Lettuce
Ideal Planting Time
Lettuce prefers cool temperatures between 60°F and 70°F (15°C to 21°C). It grows best in:
- Spring: Plant 2-4 weeks before the last frost date.
- Fall: Plant 6-8 weeks before the first frost for a second harvest.
Location
- Choose a spot with partial shade to protect lettuce from hot afternoon sun, especially in warmer climates.
- Ensure soil drains well and is rich in organic matter.
Preparing the Soil for Lettuce
Healthy soil is key to thriving lettuce plants. Here’s how to prepare it:
- Loosen soil to a depth of 8-10 inches.
- Incorporate compost or well-rotted manure to enrich nutrients.
- Aim for soil pH between 6.0 and 7.0, which is ideal for lettuce.
- Remove weeds and debris to reduce competition.
Step-by-Step Planting Guide
1. Start Seeds Indoors or Direct Sow
- Indoors: Start seeds 4-6 weeks before the last frost. Use seed trays with seed-starting mix.
- Direct sow: Plant seeds ¼ inch deep directly in garden soil once it reaches about 45°F (7°C).
2. Spacing
- Thin seedlings to 6-12 inches apart depending on variety (leaf lettuce closer, head lettuce wider).
3. Watering
- Keep soil consistently moist but not waterlogged.
- Use a gentle spray to avoid washing away seeds or damaging seedlings.
4. Mulching
- Apply organic mulch like straw to preserve moisture, suppress weeds, and maintain a cool root environment.
Caring for Your Lettuce
Watering
- Lettuce needs regular watering; aim for 1 to 1.5 inches per week.
- Water in the morning to reduce disease risk.
Fertilizing
- Use a balanced, nitrogen-rich fertilizer to promote leafy growth.
- Side-dress plants with compost or liquid fertilizer every 3 weeks.
Pest and Disease Management
Common issues include aphids, slugs, and fungal diseases.
- Control aphids with insecticidal soap or neem oil.
- Handpick slugs or use organic slug bait.
- Ensure good air circulation to prevent mildew and rot.
- Rotate crops yearly to reduce soil-borne diseases.
Harvesting Lettuce: When and How
Harvest Timing
- Leaf lettuce: Begin harvesting leaves when they reach 3-4 inches.
- Head lettuce: Harvest when heads feel firm and well-formed.
Harvest Methods
- For leaf lettuce, cut outer leaves 1 inch above soil and let inner leaves regrow.
- For head varieties, cut entire head at the base.
Pro Tip: Harvest in the morning for the freshest, crispiest leaves.
Extending Your Lettuce Growing Season
- Use row covers or cold frames to protect lettuce from frost.
- Grow heat-tolerant varieties or plant in shaded areas during summer.
- Practice succession planting by sowing seeds every 2-3 weeks for continuous harvest.
