Question
The leaves get really dark brown, black spots on them. It almost looks like black spot that roses get. I don’t water the top of the bush, unless I am fertilizing it. So I try really hard to keep the top dry. I hope you’re able to tell me what to do to prevent this from happening again this summer.
Answer
Not watering from above is going to be your first line of defense in preventing black spots on foliage. It does also depend on the type of weather during the season. Humidity and rainfall amounts also play factors in fungus showing up on foliage.
