Holly bush distress
We have two new holly bushes, which were planted last year, that are showing signs of distress. Some of their leaves are turning yellow, and my wife has noticed a large number of flies and bees on its blooms. Do you have any advice on the problem?

If you have had a lot of rain and the drainage in the area is not good, it can cause problems with leaves. Is the ground swampy? If the ground stays wet, the roots can't "breathe" and falling leaves or yellowing would be a sign of this. Too much water causes iron chlorosis.

The insects are likely visiting for pollination.
