    Hey guys help me with this one. I have some hawthornes that got brown spots on them over the winter. One especially has lost almost have of its leaves. They were planted last spring as 3 gallon plants. I also have August beauty gardenia's in the same bed with the same problem. I have not treated other than general fertilizer. Any help on guiding me through maintaining my evergreens is much appreciated. Turfgrass is my thing.

    The hawthorns have leaf spot cant really do anything to solve this problem
    i dont recommend hawthorns because of this fungus, majestic beauty hawthorns dont seem to get the spot as bad. Some fungicide will help but its not permanent if the leaves are falling off it is already bad.

    One plant is pretty bad. about 30% of the foliage is gone. And I'm starting to notice some small spots on others, but the one got hammered 1st for what ever reason.

    This is the same leaf-spot disease that affects red-tips so badly. You can use a combination of contact and systemic fungiciides (Bayleton/Daconile) however, the timing of applications for control is very important and time consuming. Most homeowners are not going to spend the time doing it nor are they going to be willing to pay for this type of service.

    I had a couple of years ago with hawthornes getting infested with bagworms. Not sure if bagworms would be a problem in the winter though. You probably would've noticed the bagworms anyways.
