I have Miss Kim Lilac Bushes. They are about 2 years old. Wonderful bushes but just today I noticed the leaves turning brown and curling just starting at the top of all my bushes. They are not touching each other. In fact I have shrub roses between all my Miss Kim's. I know the leaves curl but these are difinitely completely brown and dead. And it seems to be travelling down the plant. What can I do to save the plants. Thanks so much. Debbie

This is not my area of expertise. I often receive questions about home landscaping because it has to do with where the "family" lives. However, questions about landscaping plantings should be directed to horticulture, which is the study of plants. I forwarded your message to Sandy Mason and to her assistant. Karyn Traum. I trust that one of them will reply soon. Thanks for using Ask Extension.

Hi Debbie, even though they have been in for 2 years they are still subject to heat and drought stress. I would guess that is the culprit. You did not mention your watering practices but I would definitely water them now and as long as they have leaves. Also they can get the insect scale which appears as small "helmuts" along the stems. Otherwise you may want to take a sample to your local Extension office. You can use this website to find the one nearest you. http://web.extension.uiuc.edu good luck, Sandy
