The Q&A Archives: rhododendrons

Question: I have one plant that is drooping. I put miracle grow on them, never over water. I have sprayed around the botton for fungus and have also dusted each leaf for bugs with no success. it still appears to be green but not coming back ??

Answer: The symptoms sound suspiciously like Phytophthora Root Rot. Early symptoms of the disease include retarded growth, drooping of foliage and yellowing of leaves. Infected roots appear dark and "mushy." As the disease progresses, a browning discoloration of the wood may extend upward from the base on affected branches. Plants in poorly drained soils are very subject to waterlogging which makes them highly susceptible to this disease. If this occurs, plants may die quickly. The only way to tell if root rot or crown rot is the culprit is to dig down around the base of the tree and expose some of the roots. Wish I had something more positive to share!
