Our planting and care guide lists a few things you can do late fall to prepare it for winter. Prune off any flowers. This will keep the stems from breaking if there is a heavy snow or an ice storm. Water well, really well. Then, give it a good layer of mulch. In early spring, you can prune the branches if necessary. But, it really shouldn’t need much pruning except to clean it up some. When the temperatures even out, you can pull back the mulch away from the base of the hydrangea. Give it a little compost or fertilizer, and again, water well. Then, enjoy the flowers!
