Q. My grapes bloom then tun black before they ripen. What's going on?

Answer

Your grapes may have black rot, a fungal disease. Black rot cannot be cured once the grapes are infected, but the page linked to below details a number of integrated pest management strategies for this disease. Minimize black rot problems by removing infected fruit, cleaning up mummies, and pruning out leaves that surround fruit clusters.

Grapes are susceptible to a number of other diseases. The page linked to below describes their symptoms and management strategies, in the event that you look into black spot and determine that it is not what's affecting your plants.
