What should I do to prepare my perennials for winter? Do they need to be cut back - if so, how much? When is the best time to divide them - the fall or spring?


If your perennials are hardy to the area, let them die completely back before you cut them. But it is important that you let them die back because there is energy stored in the leaves that will return to the root or bulb when the leaves die back.

If the perennial is tender, not hardy or marginal, in our area you will need to put mulch around the plant. This will add a little protection to the root system and help keep it warmer through out the winter.

The best time to divide most perennials is when the plant is in a dormant state. This can be done in early spring or late fall.
