Overview
Growing bean beside the right neighbour
Bean (Phaseolus vulgaris) is a vegetable in the Legume family. Nitrogen-fixing legume that's easy to grow in warm weather.
Beans, corn and squash — the three sisters, still the most efficient bed there is.
Give plants 4–6 in in full sun. Aim for well-draining soil, not too rich. In most gardens the crop sits in USDA zones 2-11 and is ready in about 50-60 days.

What to plant with bean
The strongest companions for bean in this guide are Squash, Corn, Cucumber, and Pumpkin. Each pairing below is a reason to share a bed — pest masking, roots that do not compete, or insects that hunt the pests bean attracts.
Corn
Natural trellis, nitrogen fixation.
Cucumber
Nitrogen fixing benefits cucumber growth.
Pumpkin
Ground cover partnership works well.
Keep apart
What not to plant with bean

Fennel
Inhibits bean growth and germination.
Onion
Alliums stunt beans and slow nitrogen fixation.
