Cutting back perennials in the fall can be a matter of personal preference. Many perennials have attractive foliage and/ or seed heads that offer food resources and shelter for birds. With some marginally hardy perennials, leaving the stems can also aid in over-wintering, and the foliage can help insulate the crowns. Mums seem to benefit from this practice.
Removing foliage and cutting back perennials can also be done for pure aesthetics, or if your plants have been bothered by foliage diseases. Removing the old foliage and plant debris reduces the amount of inoculum present that would re-infest next year's foliage. If you choose to cut back your perennials, do so after they have gone dormant, which is usually after they have experienced several hard frosts. Cut down to within 2-3 inches of the crown to prevent any winter injury to your plants. A cover of fall leaves can also help insulate and protect your perennials through the winter months.
