Boxwood - black junk under the leaves: rot? bugs?
I have a boxwood bonsai that I got from a bonsai class last summer and it's been doing well right up until the last couple of days. There are some dark black specks under the leaves and they are sticky. The trunk of the tree has gotten a little shiny as well. Could this be some kind of bug that's gotten into the tree? Is it possible it's some kind of disease?
I'm posting this to the bonsai forum as well, but I thought I'd check here too just in case.
