Notes:

Walter and Staff, I hope you will ID the disease or condition affecting my compacta hollies shown in the three photos. I have now lost about 4 of these shrubs despite treating for both disease and insects (the white tint on the leaves is residue from my last disease/fungicide treatment. At first, the leaves turn yellow and a dead branch appears on the shrub. The yellowing continues and more dead portions of the plant appear. The infected plant dies slowly over the coarse of several months. Thanks in advance for your help.

    Could it possibly be just the effects of our prolonged drought?

    This looks like a root rot disease. I see damage like this on compacta holly every year. Some times it may be a problem brought home from the nursery. Other times I’ve seen it occur in old established plants. Check this link and the included links on the site: http://www.aces.edu/pubs/docs/A/ANR-1087/anr1087six.html
    This link has similar information but much better pictures of the problem: http://pubs.ext.vt.edu/450/450-606/450-606.html

    So what do you do to stop the problem? We have established hollies along the side of the house (probably 30 years old), and two of them have been decimated. I thought they were just suffering the effects of being overgrown, but these pictures could have been taken in my yard. Should I pull the plants while parts of them are still living? Do I need to treat the soil to prevent the spread of the rot?

    Thank you!

    Diane, the primary cause of root rot in woody ornamentals is the extremes of available moisture to the plant. Too wet and too dry. Proper mulch and proper watering are key to a plant’s health. That said, for all practical purposes, a thirty year old foundation bed of helleri or compacta hollies, at their current size, may have reached the limits of their usefulness in the landscape. A last ditch effort at saving them would be to severely prune them in late March next year: cut back to a four inch stump. Drench fungicides may be helpful at that time as you begin to regrow the plant. See the following links for additional information on root rot issues and care for woody ornamental shurbs.

    Bobby -

    Thank you for your response. The hollies are huge, and I had planned to cut them back severely in early spring, though not quite as low as you suggested. I just wasn’t sure whether it was worth trying to save these two dying bushes, or any of the bushes if the rot is going to spread. I will hack them back to a four-inch stump and see what happens.

    I am reading these comments from 2011 about Compacta Hollies and brown leaves. I do not think it is root rot. Every year I combat this with fungicide/insecticide. If I am diligent, I can arrest it… But this year it is everywhere instead of a few random spots. I think the rain last summer has effected the problem but I still don’t know if it is fungus or insect. Any updates would be appreciated to my email address.
