Winter Damage On Holly

This is classic winter damage. It usually happens as a combination of cold temperatures, wind and sun reflected off of the snow. The plant might recover, so wait at least a month to see what happens. The holly will drop all the burned leaves (you can already see that it's doing this) and there may be some die-back on the top branches. Wait until mid-May to do any pruning. At that point you'll see new growth from the stems that are still alive. Prune off any stems that are still brown in mid-May.

It would be a good idea to remove the lawn in a circle around this plant, and apply a layer of composted manure and a light application of an organic fertilizer. This will also make it easier to mow the grass around this holly. An inch of mulch over that compost will help keep the water in over the summer while the holly recovers. Next fall, in October, spray the plants with an anti-dessicant product to help protect the leaves.
