: This winter, we have noticed that the large, very well-established holly bushes in our backyard now have leaves that are turning a frosted color, as if they have been killed by the cold, harsh winter temperatures this year. We did not see this in past years, although last spring some leaves did turn brown and fell from the bushes until we gave them some Holly-Tone. What might be causing the leaves this winter to become "frostbitten"? Should we just wait until spring to give them Holly-Tone and will the bush then be able to recover? Do we prune the frosted leaves? (The holly bushes are planted very close to a moderately-sized Rose of Sharon tree but this has not appeared to have been a problem in the past.)
This has been a severe winter in many regions such as the Northeast and Mid-Atlantic areas. The hollies may be suffering from moisture loss due to cold and dry winds. There are anti-transpirants like Wilt Pruf that help in such a situation that you might consider using for next year. I am having the same problem with my Japanese hollies and have never seen this much leaf scorch from the cold in the 15 years I have lived in this house.
You might want to wait and see if the hollies put out new leaves and the old ones fall. You could try pruning a branch or two just behind the damage to see if there is any green in the branch. If not, then you can selectively prune them off.
