what is up with my holly?
have 6 or so compacta holly in my front bed. full sun from about 1 pm on. established for about 9 years now. only one of them is affected. started losing leaves a few years ago, but getting worse. soil tested - no nematodes. some leaves yellow and fall off, but there is still some new growth trying to come in on other branches. appears the branches that have lost leaves are NOT getting any new growth. but down some Hollytone a few weeks ago but so far have noticed no change. i don't see any evidence of insects or mold, etc.
