What do I do to help Knock Out Roses survive the winter in Wisconsin?

Wait until spring to trim them back if needed –otherwise just add 2-3” of mulch, leaves, or pine/fir boughs around the base of the plant –a heavy snow cover will also help insulate and protect the plant through the winter.  In spring, remove any extra mulch that may be covering around the plant too deeply and trim out any dead or broken canes.

If I live in an area with a harsh winter, what should I do to protect my Knock Out Roses?

If you live in a harsh winter climate, you should do the following:  

Mulch heavily around the base which will help keep the plant insulated.  Also, the winter winds can really dry out the plant so you may want to wrap the plant with burlap (remove in the spring after the last frost).

It's getting cold outside...what do I do with my roses that are planted in containers?

Don't panic!  Leave the containers outside through the first few frosts then bring them inside and store in a cool, dark area such as your basement or garage.  If you store your containers in the garage, remember to protect them from the winter temperatures that can come in as you open and close the door.  Store your containers inside until the threat of the last frost has passed (typically in early spring).  You'll want to check your roses periodically to make sure they don't dry out completely.
