How to Grow Lettuce in the UK

Lettuce is one of the easiest vegetables to grow in the UK. It grows quickly, doesn’t need much space, and can be grown in garden beds, raised beds, or containers.

Because lettuce prefers cooler weather, it grows especially well during spring and early summer.

Many varieties can be harvested leaf by leaf, which makes them ideal for beginners.

When to plant lettuce

Lettuce seeds can usually be sown between March and September in the UK.

For the best results, sow small batches every few weeks. This keeps fresh lettuce growing throughout the season.

Lettuce grows best in mild temperatures and may struggle during very hot weather.

Where to grow lettuce

Lettuce grows well in:

  • garden beds

  • raised beds

  • containers

  • window boxes

It prefers:

  • a sunny or partially shaded spot

  • shelter from strong wind

  • soil that stays moist

Containers are especially useful for keeping lettuce easy to reach and harvest.

Soil requirements

Lettuce grows best in soil that:

Dry soil can cause lettuce to grow slowly or taste bitter.

Adding compost before planting helps lettuce grow quickly.
