Question From: D. BEHR - Rockford, Illinois, United States
Q: I have an indoor greenhouse work lots of plants in a bed. My begonia had big beautiful leaves which have started curling and drying up. The soil is not dry. Am concern it's from the air conditioning and the air being too dry. Have been misting the plant every day. Could this be some type of fungal disease or is it a humidity problem? I use water from a fish tank every week.
A: Excessive water, lack of water and/or low humidity will all cause leaf curl. Try putting the plant on a humidity tray. That's a large diameter tray filled with stones and water to a level just below the tops of the stones. Google "making a humidty tray - UTube" for instructions. Best And Happy Yardening, Nancy
