The Q&A Archives: Knnock out Roses Wintering

Question: I have ten Knowck out roses that came from your company. They are beautiful, and now we are heading into Fall and then winter. I bought the knock out rose because it sounded maintenance free.

What do I have to do to these roses to get them through the winter.

Answer: Assuming they are grown on their own roots (or if grafted, the graft should be planted below the soil) they should be just fine. Mulch heavily in late fall after a few freezes. In early spring cut them back to remove any winter damage or to about a foot high, which ever is more. Gradually remove the excess mulch to leave a layer about three inches deep. Also fertilize and/or topdress with compost in early spring. Even if they die back to the ground they should regrow and bloom next summer.
