How to Grow Lettuce: Step-by-Step

1. Choose the Right Location

Lettuce prefers full sun to partial shade.
In hotter climates, provide shade during the afternoon to prevent bolting (premature flowering).

2. Prepare the Soil

Lettuce thrives in well-draining, fertile soil with a pH of 6.0–7.0.
Enrich the soil with compost or organic matter before planting.

3. Sow the Seeds

Directly sow seeds 0.5–1cm deep and 15–20cm apart in rows.
Cover lightly with soil and water gently.

4. Thin the Seedlings

Once seedlings are 5cm tall, thin them to the appropriate spacing for the variety, usually 15–30cm apart.

Caring for Lettuce Plants

Watering
- Keep the soil consistently moist, as lettuce has shallow roots. Water at the base to avoid wetting the leaves.
Fertilizing
- Apply a balanced fertilizer every 4–6 weeks to promote healthy growth.
Weeding
- Remove weeds promptly to prevent competition for nutrients and water.
Mulching
- Apply mulch around the plants to retain soil moisture and regulate temperature.
Preventing Bolting
- Provide shade during hot weather and keep the soil evenly moist to delay bolting.

Growing Lettuce in Containers

Choose the Right Container
- Use a pot or trough that’s at least 15–20cm deep with good drainage.
Soil Preparation
- Fill the container with a nutrient-rich, well-draining potting mix.
Planting
- Sow seeds or transplant seedlings, spacing them 15–20cm apart.
Placement
- Place the container in a sunny spot, ensuring it receives 4–6 hours of light daily.

Harvesting Lettuce

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

Common Problems and Solutions

Bolting
- Cause: Hot temperatures or stress.
- Solution: Provide shade and keep the soil moist.
Yellow Leaves
- Cause: Overwatering or nutrient deficiency.
- Solution: Improve drainage and apply a balanced fertilizer.
Pests
- Common Culprits: Aphids, slugs, and snails.

Diseases
- Symptoms: Powdery mildew or rot.
- Solution: Ensure proper air circulation and avoid overhead watering.
