Question From: j. loveland - Delphi, Indiana, United States
Q: a few of my wax begonia leaves are getting brown spot. I read it could be because of water spot. you can't keep the rain off. is there another reason?

A: Water does not cause spotting due to moisture on the leaves. Excessive heat, direct sun and fertilizer burn will cause spotting. Best And Happy Yardening, Nancy
