We have 3 holly bushes and 2 have white worm like things on them. The leaves of one of them are turning yellow. What is it and how do we treat it? We don't want to lose these bushes. They have been planted for 10 or more years.

Certified ExpertA.I am not sure exactly what they are, but if you send a picture, we should be able to identify them. Regardless, we have found neem oil effective on most damaging pests. Here is more information on neem oil:

Our north facing, 13-year-old Holly is dropping its leaves. No insect problem that I can see. Nothing different has been done to the bush. We live in southwest Ohio. The stems of the affected area is just drying up and dying. Any suggestions?

Certified ExpertA.This could be a watering or nutrient issue. Give it more water and have the soil tested to find out if it is deficient in anything, then fix as needed.

May 28, 2011Q.Holly Bush
Holly leaves are turning brown and then stem is dying--more in the middle of the bush. It has always been healthy and I have had it for years. What can I do to save it? It started last summer and is much worse this spring.

Certified ExpertA.There are a few things that can cause this. Holly scorch is the most common. This happens when the weather changes too quickly. The plant will recover from this on its own.
