|IT SEEMS THAT I HAVE A ROSE BUSH THAT IS GRAFTED. I HAVE TWO DIFFERENT BUSHES GROWING FROM THE SAME PLANT. HOW DO I TELL WHICH CANES TO REMOVE SO THAT I CAN GET MY ORIGINAL ROSE BACK? DO I REMOVE ALL CANES GROWING FROM BENEATH GROUND LEVEL, AND LEAVE THE ONES GROWING FROM ABOVE GROUND LEVAL?
|You need to cut out all of the canes growing from the rootstock, these would originate from below the graft. First figure out which canes are from the desired rose, and which are from the root stock. Usually, the root stock growth is much thornier than the desired rose and often it is much more vigorous. If you aren't sure, dig (gently) down until you find the graft and can see where they start. In your area, the graft might be at ground level or up to five inches below the soil surface, depending on who planted the rose and their feelings on winter hardiness. From now on, remove any root stock growth as soon as it appears.
