The Q&A Archives: White Spots On Bushes

Question: I have a bush that has some type of fungus growing on it. The leaves have white spots on it and the branches have some type of white powder on them. Can you give me advice on how to stop the fungus? Do you sell any products that can help? The bush has lost about 3/4 of its leaves, can it be cured?

Answer: Based on your description it sounds like the plant is suffering from a fungal infection, possibly mildew. It is difficult to make a diagnosis however without knowning what plant it is. In general, the best ways to deal with this are: avoid wetting the foliage, increase air circulation, remove infected leaves early to avoid reinfection, dispose of any fallen infected leaves, and if needed, treat with an appropriate product labeled for use on that particular plant. Your county extension (461-1000) should be able to help you identify the plant, the specific cause of the problem, and suggest what to do or use. I'm sorry about your plant.
