3. Temperature
   • Grows best in cooler temperatures between 10–20°C. Protect from excessive heat to prevent bolting.
4. Watering
   • Needs consistent moisture to produce tender leaves.

How to Plant Lettuce

1. Starting from Seeds

• Sow seeds 0.5–1cm deep and space them 15–20cm apart for leaf varieties and 20–30cm for head varieties.
• Cover lightly with soil and water gently.

2. Transplanting Seedlings

• Space seedlings 15–30cm apart, depending on the variety.
• Transplant in early spring or late summer for optimal growth.

3. Indoor Planting

• Sow seeds or plant seedlings in containers and place them near a sunny window or under grow lights.

Caring for Lettuce Plants

1. Watering
   • Keep the soil consistently moist but avoid waterlogging. Water early in the day to reduce the risk of fungal diseases.
2. Fertilizing
   • Use a balanced fertilizer every 4–6 weeks to encourage healthy growth.
3. Mulching
   • Mulch around plants to retain moisture, regulate soil temperature, and suppress weeds.
4. Weeding
   • Remove weeds promptly to reduce competition for nutrients and water.
5. Shading
   • Provide shade during hot weather to prevent bolting and keep leaves tender.

Growing Lettuce Plants in Containers

1. Container Selection
   • Use pots or troughs at least 15–20cm deep with drainage holes.
2. Soil Preparation
   • Fill the container with a nutrient-rich, well-draining potting mix.
3. Placement
   • Place containers in a sunny spot, ensuring 4–6 hours of light daily.
4. Watering and Feeding
   • Water regularly and fertilize every 2–3 weeks to replenish nutrients in the potting soil.

Harvesting Lettuce Plants

1. When to Harvest
   • Leaf lettuce can be harvested 30–45 days after planting.
   • Head lettuce varieties take 45–75 days to mature.
2. How to Harvest
   • For leaf lettuce, snip outer leaves as needed, allowing the plant to continue growing.
   • For head lettuce, cut the entire head at the base when fully mature.
3. Storage
   • Store harvested lettuce in the refrigerator for up to a week. Wash and dry leaves before storing.

Common Problems with Lettuce Plants

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

Tips for Growing Healthy Lettuce Plants

1. Succession Planting
   • Sow seeds every 2–3 weeks for a continuous harvest throughout the growing season.
2. Harvest Regularly
   • Regular harvesting encourages new growth and prevents overcrowding.
3. Use Companion Planting
   • Grow lettuce near carrots, radishes, or onions to maximize garden space and deter pests.
4. Provide Shade in Hot Weather
   • Use shade cloth or plant lettuce near taller crops for protection from intense sunlight.
5. Rotate Crops
   • Avoid planting lettuce in the same spot each year to reduce the risk of soil-borne diseases.

Benefits of Growing Lettuce Plants

   • Homegrown lettuce tastes fresher and has more nutrients than store-bought options.
2. Quick Results
   • Lettuce is one of the fastest-growing vegetables, making it ideal for beginners.
