Growing it

Propagation: seed
When to plant: spring, early summer
Overwintering: This plant is an annual and will die with the first frost, so remove debris after harvest.
In containers: Bush beans grow very well in containers, provided the pot is at least 12 inches deep.

Direct Sowing

Wait until the soil is warm and the danger of frost has passed.
Plant seeds 1 inch deep in well draining soil.
Space seeds 3 to 4 inches apart in rows.

Planting beans with corn and squash creates the classic Three Sisters garden, where each plant supports the others.

Grows well with

Corn — Corn provides a natural trellis for pole beans to climb.
Summer Savory — It is said to improve the flavor of beans and deter bean beetles.

Keep away from

Onion — Onions are thought to stunt the growth of beans when planted in close proximity.

Similar species

Lima bean — A related legume with similar growth habits but different seed shapes.
Runner bean — A vigorous climber often grown for both ornamental flowers and edible pods.
