When to Harvest Lettuce

Lettuce can be harvested once leaves reach a usable size. Because lettuce grows quickly, harvesting can often begin just a few weeks after planting.

Regular harvesting encourages plants to continue producing fresh leaves.

In the UK, lettuce is usually harvested from spring through autumn, depending on when it was planted.

Harvesting leaf lettuce

Leaf lettuce can be harvested by picking outer leaves as needed.

This allows the plant to keep growing and producing new leaves.

Frequent harvesting often produces the best results.

Harvesting whole lettuce plants

Some lettuce varieties form heads.

These can be harvested by cutting the plant at the base once the head has formed.

Harvesting before hot weather helps maintain flavour.

Harvesting regularly

Checking lettuce every few days helps prevent leaves from becoming too large or bitter.

Younger leaves are often more tender.

Regular harvesting encourages steady growth.

Harvesting container lettuce

Container-grown lettuce can be harvested in the same way as garden-grown plants.

For container advice, see growing lettuce in containers.

Lettuce harvest season in the UK

Lettuce can be harvested throughout the growing season when planted regularly.

Small, repeated sowings often provide a continuous supply of leaves.
