|Several stems of my Hydrangea macrophylla dye off while the rest of the plant thrives - what might cause this and how do I prevent it?|
|It's difficult to tell what's going on without being able to see the plant. Check for insect or disease problem. Mites can feed on a plant and kill leaves and stems; diseases can affect only parts of a plant. I'd prune off the dead stems and carefully inspect them for signs of insects or diseases. Or, you can take the cuttings to your local cooperative extension office for positive diagnosis and suggested remedies. Contact: Broward County Co-Op Extension, 3245 College Avenue,
