| Bush beans like growing in the cooler temperatures of early spring. Curling leaves can indicate a water stress or even heat stress. Brown spots might indicate a disease of some sort or may simply be the result of sunscald - especially if droplets of water remain on the leaves in the hot sunshine. The droplets act like little magnifying glasses and concentrate the sun's rays which can actually burn the tissues of the leaves. It's really difficult to diagnose a plant problem without seeing it so I hope the above helps you determine just what the problem might be with your bush beans. |
