I have ten big rhodos at the back of my property. I lost one this winter. It has turned all brown. The others look stressed and the leaf tips are burned back. I think that these plants are suffering and I don't want to loose them. They provide a nice screening effect between my house and my neighbors. Can you recommend the best fertilizer to feed them. I want to be sure that its safe and effective. What should I do?

It sounds as if your rhododendrons were burned by the cold dessicating winter winds. The rhodos may drop some leaves before they start to recover. Before next winter you might consider spraying an anti dessicant lightly on these plants. I know of one, sold under the brand name Wilt Proof. The anti dessicant lightly coats the plant leaf with a natural waxy coating and this will protect the leaves from winter burn. A good natural slow release gentle feeding will help your rhodos to recover I recommend Jonathan Green's Holly Care 4-6-4 fertilizer. This is a special fertilizer formulated for all acid loving shrubs such as Hollies, Azaleas, Arborvitaes and of course Rhododendrons. Holly Care will promote deep-green leaves and more beautiful blossoms and berries on your shrubs.
