The Q&A Archives: winter preparation

Question: Do I need to trim back the branches of lavendar and russian sage before snow fall, or do I let it winterize itself, and leave as is? I live in Steamboat Springs, Northwest mountains of Colorado. Thanks! Camille

Answer: 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 will provide some winter protection; apply a light, airy mulch such as pine boughs after the ground freezes.
