In my garden I leave the foliage on woody perennials until the following spring. Then I cut back anything that has been killed by winter weather. It is important to leave the foliage intact while it is still green so the root system can store up enough food energy for the long hibernation. Mulching is not necessary, but if you wish to do so, apply a light, airy mulch such as pine boughs after the ground freezes.
