Overview
Growing lettuce beside the right neighbour
Lettuce (Lactuca sativa) is a vegetable in the Aster family. Cool-season leafy green that prefers shade in summer.
Sow radish between lettuce — it is out of the ground before the heads need room.
Give plants 6–12 in in sun or part shade. Aim for moist, well-draining, fertile soil. In most gardens the crop sits in USDA zones 2-11 and is ready in about 30-60 days.

What to plant with lettuce
The strongest companions for lettuce in this guide are Carrot, Radish, Strawberry, and Beet. Each pairing below is a reason to share a bed — pest masking, roots that do not compete, or insects that hunt the pests lettuce attracts.
Radish
Fast growing, helps break soil compaction.
Strawberry
Ground cover partnership, space efficient.
Beet
Different depth roots, complementary growth.
Keep apart
What not to plant with lettuce

Cabbage
Both attract same pests and compete for space.
