Re: Rosa eglanteria/rose gall

First, I would make sure you have "rose gall," and not "crown gall," which
is a serious bacterial disease. Second, since you have established a
pattern, it appears like removing that particular plant *may* provide
relief. In my experience, however, the wasps that are responsible will
merely select another victim if their preferred host in unavailable. How bad
is this problem? removing a cane or two should be all that is required to
eliminate the problem.
