Frequently Asked Questions

Should I grow climbing or dwarf French Beans?

It depends on your space — French Beans are available in both climbing and dwarf varieties, and the compact dwarf types are ideal for small gardens while climbing types need a support structure but save ground space.

Why should I avoid overhead watering on French Beans?

Watering regularly once pods are forming is important, but avoiding overhead watering helps prevent fungal diseases like blight and rust from spreading on wet foliage — water at the base instead.
