Q.Nellie R Stevens Problem
I have a Nellie R Stevens that has developed what looks like small white cups, almost like small popcorn, on some of the trunk and branches. When I removed one, something that looked like blood (dark red or red brown) came out. Can you identify what it might be and how to get rid of it? I cannot seem to be able to id it.
