Susan at Earthly Garden has a post everyone who is wondering how to winterize their roses should read. Here’s a bit of the post:

First, stop feeding them. With the cool weather approaching you don’t
want to encourage new growth, which will not survive. This is also the
time to stop deadheading. Let the plant produce rosehips. This tells
the plant it’s time to slow down and begin preparing for dormancy, and
will also provide food for birds over the winter. Once the hips have
formed you can remove the spent blooms.

The rest of the post has good advice on preparing your roses for the coming winter. I’ve still been deadheading my roses, and I need to stop before the winter weather sets in. Fortunately, it’s still warm here in Tennessee!
