Big brown patches have started appearing on my French Bean leaves. Lower two tiers only, the rest of the plant still growing OK. The leaves eventually shrivel and die.
I grew the plants from seed in my conservatory, planting out 2 to 3 weeks ago. They are in a south facing alley to the side of my house in raised beds. Very warm part of the garden and a sun trap, although it sometimes becomes a wind tunnel.
Anyone able to help? Thanks in advance.<img src="/uploads/images/original/8121.jpg" alt="/uploads/images/original/8121.jpg" width="512" height="350" />
