|I purchase 3 little rascal hollies about 2 years ago, and they were planted in a south exposure (almost full sun with about 20% of decidious morning shade). The hollies were wonderfull until the first winter came along, and they never recovered. They lost 50% of their leaves and appear to have rust, but I have tried 3 different kinds of foliar fungicide (neem oil, daconazole, and I can't recall the 3rd. one), but nothing seems to work. I am very frustrated, and if I can not do anything to improve the health of those hollies, I am probably going to pull them this coming spring. Any last resort suggestions???
|Winter stress due to sun reflecting off a building along with winter wind can really damage broadleaf evergreen foliage such as these. If the location where they are planted is like that, there might not be much you can do to keep them healthy. There are a number of leaf spots and other foliage problems that can potentially affect hollies. You would need to know specifically what is affecting them in order to select the right treatment and to know how/when is the right time of year to apply it to control the problem. I would suggest you work with your county extension to obtain a definite diagnosis of the spots and then based on that, determine how to proceed. If it is something that needs a chemical control they will have the most up to date information on what to use and how best to apply it. I'm sorry you are having trouble with your Little Rascals, usually they are quite trouble-free.|
