🧑🌾 How to Grow Lettuce in Winter
Lettuce grows best in full sun to light shade and enjoys cool, moist conditions. Winter growing means less risk of bolting and better flavour.
| Step | Details |
|---|---|
| Soil Preparation | Use rich, well-drained soil improved with compost or aged manure. Aim for pH 6.0–7.0. |
| Sowing Method | Sow seeds directly into garden beds or start in trays and transplant when seedlings are 4–6 cm tall. |
| Spacing | For full heads, space 20–30 cm apart. For baby leaf harvest, sow in dense rows and thin as needed. |
| Sunlight | Lettuce grows best in full sun to part shade. Aim for 4–6 hours of light per day. |
| Watering | Keep soil consistently moist, but not soggy. Water early in the day and mulch to retain moisture. |
| Germination Temperature | Seeds germinate best between 5–20°C. Cooler temperatures slow growth but improve flavour. |
| Feeding | Feed with diluted seaweed solution or compost tea every 2–3 weeks to maintain healthy growth. |
| Time to Harvest | Baby leaves ready in 3–4 weeks. Full-size heads mature in 6–9 weeks depending on variety. |
🐛 Common Problems & How to Fix Them
- Slugs & snails: Use iron phosphate pellets or beer traps. Mulch with straw to deter crawling pests.
- Tip burn: Caused by inconsistent watering or heat stress. Keep soil moist and avoid over-fertilising.
- Aphids: Hose off or apply insecticidal soap. Companion plant with coriander or dill to attract predators.
- Downy mildew: Improve air circulation, water at the base, and avoid wetting leaves in the evening.
✂️ When and How to Harvest
Lettuce can be harvested as:
- Baby leaf: Cut leaves when 7–10 cm tall (around 3–4 weeks).
- Cut-and-come-again: Snip outer leaves from mature plants to allow regrowth.
- Full head: Cut entire head at the base once mature (usually 6–9 weeks).
Harvest early in the morning for the crispest, most hydrated leaves.

❓ FAQs About Growing Lettuce in Winter
Can I grow lettuce in pots?
Yes! Lettuce grows well in containers, especially loose-leaf and butterhead types. Use a deep pot with good drainage and quality potting mix. Keep it in a sunny position and water regularly to keep soil moist.
How do I protect lettuce from slugs and snails?
Use barriers like copper tape or crushed eggshells around the plants. You can also try beer traps or iron-based pellets. Raised beds and pots also reduce slug pressure.
How often should I water my lettuce?
Lettuce needs consistent moisture. Water every few days, or daily in dry weather, aiming to keep the soil lightly moist but not soggy. Mulching helps retain water and reduces weeds.
Can I grow lettuce with other vegetables?
Absolutely! Lettuce is a great companion plant. It grows well with carrots, beetroot, onions, spring onions, radishes, and herbs like dill and coriander. Avoid planting too close to brassicas (like broccoli), which may shade it out or compete for nutrients.
Why is my lettuce bitter?
Bitterness can result from stress due to heat, underwatering, or the plant nearing the end of its life cycle (bolting). Grow lettuce in cool seasons, keep it well-watered, and harvest before it starts to form a central stalk.
