Fall Perennial Cleanup: To Cut or Not to Cut? And Winter Mulching Tips

In Zone 5, wait until the first hard frost to cut back perennials. Some plants (see previous article) should not be cut to the ground.

Winter Mulching

  • Wood chips are excellent for preventing frost heaving.
  • Apply 2–3 inches after the ground freezes.
  • Keep mulch away from crowns to prevent rot.

Why Wait for Frost?

Cutting too early stimulates tender growth that winter kills. Frost signals the plant to harden off.

For plant-specific advice, submit a list of your perennials.
