Dealing with Plant Disease

The two most-common causes of plant disease are bacteria and fungi, with fungi causing up to 85% of plant disease. It's important to determine the cause of the problem with your plant before attempting to treat it. Don't water a diseased plant—this will only help spread the disease to other plants.
