Q.Rainbow Lucthothie
I have 3 plants in the front of my house and one in my back yard. They all have black spots on their leaves. Can you give me advice.

Leucothoe is susceptible to a disease called Cylindrocladium leaf spot, caused by a fungus, and it looks like that's what yours has. Providing the plant with the environmental conditions it prefers and avoiding overhead watering are the most important measures to take. Applying a fungicide intended for ornamental plants may also help.
