black spots, poor color on Nandina

I have had my nandina for two years, although they are growing and appear "structurally" healthy, the leaves often develop black spots or edges, and the colors are very washed out. What is the problem?

"Hi,

Thanks for writing. There are several common leaf spot diseases that attack nandina. Your best bet is to look for disease-resistant cultivars and make sure your plants are in a sunny spot (the more shade they're in, the more likely they are to become diseased).

During periods of moist weather, spraying them with a fungicide labeled for use on leaf spots can help keep the disease at bay. But fungicides, unfortunately, can't be used to cure disease once it's already attacked.
