Knock Out Rose Winter Care: Mulch Over Cones

Knock Out Rose Winter Care: Mulch Over Cones

In Zone 5, Knock Outs (hardy to Zone 4) need only an 8-inch soil/mulch mound after hard frosts.

Key Points

Don't fertilize after mid-August for proper hardening.
Prune to 2 ft now; for smaller bushes, prune to 12 inches next spring.
If using cones, wait until leaves drop after hard frosts (frozen soil).
Early coning creates greenhouse effect, causing tender growth that dies.
