Chocolate spot: brown spots on broad bean leaves

Small chocolate-brown spots on the leaves, worst in damp, crowded autumn sowings.

When it shows up: Autumn to spring, in damp weather

What to do

  1. Give plants room: don’t sow closer than 20 cm.

  2. Pick off the worst leaves.

  3. Most plants still crop well, so there’s no need to pull them.
