Last spring I had three cone shaped holly bushes planted. They did well all summer, fall and winter until recently. Our spring has been very wet and the leaves are turning yellow. I fed them in the early spring with Holly Tone. What do I do to save these bushes?

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.
