Lettuce Overview

Lettuce is an edible, leafy herbaceous biennial that is grown as an annual. The leaves - notched, scalloped, frilly or ruffled - are generally eaten raw in salads and are a rich source of vitamins K and A. Depending on the variety, lettuce plants can vary in size, shape and colour but generally, the leaves form a dense head or a loose rosette of green or red, or a mixture of the two. If allowed to bolt or go to seed, the flowers will be yellow, followed by hairy brown seed heads. Lettuce is a 'cool-season' crop that grows well in the spring, and autumn, as well as the summer and some lettuce seedlings will tolerate a light frost. It's a good idea to make regular sowings for a constant supply. They need a lot of water for the few weeks before harvesting.

Common problems with Lettuce

How to harvest Lettuce

Lettuce matures in 45-100 days depending on the variety. Harvest lettuce in the morning, after the plants have had all night to plump up with water. Pull young plants thinning them creating space for the remaining plants and providing the space needed for bigger plants. Gather individual leaves as needed or use scissors to quickly cut fresh leaves.

How to propagate Lettuce


Direct sow or transplant in Spring. Direct sow shallowly, 2.5 cm apart in rows 30-45 cm apart. Germinates in 7-14 days.
