Q.White Spots/Insects on Holly Shrubs
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.

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:
