Knnock out Roses Wintering - Knowledgebase Question

Question by johnbrown8

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.

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.
