How to Plant Lettuce: Step-by-Step

1. Prepare the Soil

• Choose a sunny or partially shaded spot with well-draining soil.
• Enrich the soil with compost or organic matter to improve fertility.

2. Choose the Planting Method

• Direct Sowing: Sow seeds 0.5–1cm deep directly into the soil. Space seeds 15–20cm apart for leaf varieties and 20–30cm apart for head varieties.
• Transplanting Seedlings: Start seeds indoors 4–6 weeks before the last frost and transplant young plants into the garden or containers.

3. Water Thoroughly

• Water the soil immediately after planting to settle the seeds or seedlings.

4. Thin the Seedlings

• Once seedlings are 5cm tall, thin them to the appropriate spacing for proper growth. Use the thinned seedlings in salads.

Caring for Lettuce Plants

1. Watering
   • Keep the soil evenly moist but not waterlogged. Lettuce has shallow roots and thrives in consistent moisture.
2. Fertilizing
   • Apply a balanced fertilizer every 4–6 weeks to promote healthy growth.
3. Mulching
   • Use mulch to retain soil moisture, regulate temperature, and suppress weeds.
4. Weeding
   • Remove weeds regularly to reduce competition for nutrients and water.
5. Protecting from Heat
   • In hot climates, provide shade or plant lettuce near taller crops to shield it from intense sunlight.

Growing Lettuce in Containers

1. Choose the Right Container
   • Use a pot or trough at least 15–20cm deep with drainage holes.
2. Soil Preparation
   • Fill the container with nutrient-rich, well-draining potting soil.
3. Planting
   • Sow seeds or transplant seedlings, spacing them appropriately based on the variety.
4. Placement
   • Place the container in a location with 4–6 hours of sunlight daily or under grow lights indoors.
5. Watering and Feeding
   • Water consistently and fertilize every 3–4 weeks to maintain soil fertility.

Harvesting Lettuce

1. When to Harvest
   • Leaf lettuce is ready 30–45 days after planting.
   • Head lettuce varieties take 45–75 days to mature.
2. How to Harvest
   • For leaf lettuce, pick outer leaves as needed while leaving the center to regrow.
   • For head lettuce, cut the entire head at the base when fully formed.
3. Storage
   • Store harvested lettuce in the refrigerator for up to a week. Wash and dry leaves before storing.

Common Problems When Planting Lettuce

1. Bolting
   • Cause: High temperatures or inconsistent watering.
   • Solution: Provide shade and maintain consistent moisture to prevent bolting.
2. Yellow Leaves
   • Cause: Overwatering or nutrient deficiency.
   • Solution: Improve soil drainage and fertilize regularly.
3. Slow Growth
   • Cause: Poor soil quality or insufficient sunlight.
   • Solution: Enrich the soil and ensure proper light exposure.
4. Pests
   • Common Culprits: Aphids, slugs, and snails.
   • Solution: Use organic pest control methods like neem oil or diatomaceous earth.

Tips for Successful Lettuce Planting

1. Succession Planting
   • Sow seeds every 2–3 weeks for a continuous supply of fresh greens.
2. Choose the Right Variety
   • Select lettuce types suited to your climate and growing conditions.
3. Harvest Regularly
