Growing Conditions:
- Climate: Prefers cool weather, making it ideal for spring and fall planting. It tolerates heat better than other lettuce types but may bolt in extreme heat.
- Soil: Thrives in well-drained, nutrient-rich soil with a pH of 6.0–7.0. Adding compost or organic matter improves growth.
- Spacing: Space plants about 12–18 inches apart to allow for full head formation. Rows should be 18–24 inches apart.
Planting Instructions:
Sowing Seeds:
- Directly sow seeds in the garden after the last frost in spring or 8–10 weeks before the first frost in fall.
- Cover seeds lightly with soil and water gently. Seeds will germinate in 7–10 days.
Transplanting:
- Start seeds indoors 4–6 weeks before the last frost. Transplant seedlings into the garden when they are 2–3 inches tall.
Care Tips:
- Watering: Maintain consistent soil moisture to encourage tender, crisp leaves. Water at the base of the plant to avoid wetting leaves and reduce the risk of disease.
- Fertilizing: Use a nitrogen-rich fertilizer to support leafy growth, but don’t over-fertilize as it can cause bitterness.
- Mulching: Mulch around the base to retain soil moisture and prevent weeds.
- Pest Control: Look out for aphids, slugs, and snails. Use organic deterrents like neem oil or diatomaceous earth if needed.
Harvesting:
- Baby Leaves: Start harvesting outer leaves when they are 3–4 inches long. This allows the plant to continue growing.
- Full Heads: Harvest when the head is firm and about 8–10 inches tall. Cut the plant at the base with a sharp knife.
- Timing: Harvest early in the morning for the freshest and crispiest leaves.
