When to Plant Lettuce in the UK
Lettuce can be grown nearly year-round with the right approach:
Sowing Method | UK Timing |
---|---|
Indoors or undercover | January to March |
Outdoors (main season) | March to August |
Autumn sowing (for winter harvest) | September to October |
Step-by-Step: How to Plant Lettuce
Step 1: Choose the Right Location
Lettuce grows best in:
- Full sun to partial shade
- Well-drained, fertile soil
- Sheltered areas that protect from strong winds
In hot summers, partial shade helps prevent bolting (premature flowering).
Step 2: Prepare the Soil or Container
Lettuce enjoys:
- Moist, rich soil with plenty of compost or well-rotted manure
- pH of 6.0 to 7.0
Raised Beds or Ground Soil:
- Add compost and rake to a fine tilth
- Water the soil before sowing
Containers:
- Choose a wide, shallow container with good drainage
- Use multipurpose compost mixed with perlite or vermiculite
- Water regularly to avoid drying out
Step 3: Sow Lettuce Seeds
Indoor Sowing:
- Sow 1 seed per module or tray cell, 0.5cm deep
- Keep in a bright, cool place (15–18°C)
- Transplant when seedlings have 3–4 leaves
Outdoor Sowing:
- Sow thinly in rows 30cm apart
- Cover seeds lightly with soil and water gently
- Thin seedlings to 15–30cm apart depending on type
Succession Sowing Tip: Sow every 2–3 weeks from March to July for a continuous supply.
Caring for Lettuce Plants
1. Watering
- Water regularly to keep soil consistently moist
- Avoid waterlogging but never let the soil dry out, especially in containers
- Water in the morning to prevent mildew
2. Feeding
- Lettuce is a light feeder
- Use a diluted liquid seaweed or all-purpose feed every 2 weeks for leafy growth
3. Thinning and Spacing
- Thin seedlings early to prevent overcrowding
- Final spacing:
- Loose-leaf: 15–20cm apart
- Cos, Butterhead: 25–30cm apart
- Crisphead: 30–40cm apart
Protecting Lettuce from Pests and Problems
Pest/Disease | Symptoms | Solutions |
---|---|---|
Slugs and snails | Ragged holes, missing seedlings | Use beer traps, copper tape, or organic pellets |
Aphids | Sticky leaves, curled growth | Use insecticidal soap or attract ladybirds |
Cutworms | Seedlings cut at soil level | Use collars or keep soil clean of debris |
Bolting | Lettuce flowers early, bitter leaves | Provide shade, keep soil moist, choose bolt-resistant varieties |
Downy mildew | Yellow spots on leaves | Improve airflow, water early, avoid overcrowding |
Harvesting Lettuce
Loose-Leaf Types (Cut-and-Come-Again):
- Start harvesting 4–6 weeks after sowing
- Snip outer leaves with scissors, leaving the centre to regrow
- Can be harvested multiple times
Head-Forming Types:
- Harvest when heads feel firm and well-formed
- Cut at the base with a sharp knife
- Remove outer leaves to reveal fresh, clean hearts
Tip: Harvest in the morning when leaves are crisp and full of moisture.
Storing and Using Lettuce
Short-Term Storage:
- Keep in the fridge in a sealed bag or container
- Store unwashed to prevent early wilting
- Best eaten within 3–5 days of harvest
Washing and Preparing:
- Wash in cold water to revive wilted leaves
- Use a salad spinner or pat dry gently
- Mix varieties for texture and taste
Creative Uses:
- Classic salads
- Lettuce wraps or taco shells
- Stir-fried with garlic and soy
- Smoothies (yes, really!) for a vitamin boost
Growing Lettuce in Containers or Small Spaces
Perfect for balconies, patios, or windowsills!
How-To:
- Use shallow pots or troughs
- Choose compact or loose-leaf varieties
- Water daily in hot weather
- Harvest frequently for continual regrowth
Bonus Tip: Interplant with herbs like parsley or chives for flavour and pest control.
Year-Round Lettuce Growing Tips
Spring to Summer:
- Sow outdoors regularly
- Use light shading in midsummer to prevent bolting
Autumn to Winter:
- Sow cold-tolerant varieties like Winter Density or Arctic King
- Grow under cloches, cold frames, or fleece tunnels
- Ideal for mild winters or protected raised beds
Companion Planting with Lettuce
Good Companions:
- Carrots – help break up the soil
- Radishes – grow quickly and help space plants
- Onions – deter aphids
- Marigolds – repel pests and attract beneficial insects
Avoid Planting Near:
- Cabbages and brassicas – may compete for space and nutrients
Crop Rotation and Aftercare
- Rotate lettuce with legumes or root vegetables
- Avoid replanting in the same bed for at least two years to reduce disease risk
- Add compost or mulch after each harvest to replenish the soil
