Roseum Elegans Struggling
I am trying to find out how to prevent a Roseum Elegans Rhododendron from getting further deteriorated. ItÂs showing some insect chewing damage and some branches are dying. Please take a look at the photo:
I read chewing damage might be due weevil insects. Nematodes are recommended to put on the soil to go after them. Can you tell if there is anything else I could do? Or if my assumption is correct?
My goal is to obviously get it as healthy as possible, and promote branches since I want the round dense shape.
I will greatly appreciate advice.
