When to Harvest Leeks

Leeks are ready to harvest once stems reach a usable size. Because leeks grow slowly, they are often harvested later in the growing season.

In the UK, leeks are usually harvested during autumn and winter, depending on planting time.

Leeks can often remain in the ground until needed.

Signs leeks are ready to harvest

Leeks are usually ready when:

  • stems have thickened

  • plants are well established

  • leaves are tall and healthy

Larger stems usually produce better harvests.

Harvesting leeks carefully

Loosen the soil around the plant before pulling leeks from the ground.

Pull gently from the base of the leaves.

This helps avoid damaging the stem.

Harvesting container leeks

Leeks growing in containers can be harvested by loosening compost around the roots.

For container advice, see growing leeks in containers.

Leek harvest season in the UK
