Questions about broad beans

When to sow broad beans?

In zone 8: sow direct from October to November and from February to March. The four other zones are in the calendar above; at altitude or after a long winter, aim for the end of the window.

How long until harvest?

About 110 days after sowing in zone 8, then the harvest lasts about 20 days.

How far apart?

15 cm between plants along the row and 40 cm between rows.

Can you grow broad beans in a pot?

Yes, in a deep enough pot, in the sun shown above. Soil dries fast in a pot: watch the watering more than in the ground.

What to plant nearby?

Good companions: carrot, lettuce, potato and spinach. Keep apart: chives, garlic, leek and onion.
