|I HAVE JUST MOVED TO A NEW HOUSE THE THE PREVIOUS OWNERS LEFT THE ROSES WITH BLOOMS ON THEM. WHEN SHOULD I TRIM THEM OFF AND HOW SHORT SHOULD I TRIM THE ROSE ITSELF. I AM PRETTY SURE I DON'T DO ANYTHING UNTIL SPRING BUT NEED TO KNOW HOW TO PRUNE THEM - THEY ARE IN A BED (6 ROSE BUSHES) WITH MULCH AND ARE ABOUT 3 1/2' TALL (I THINK PLANTED IN 2003. THANKS FOR ANY HELP YOU CAN GIVE ME. LANA BIRKY|
|Wait until your rose begin to show some signs of waking up from their dormant period. Just watch for swellings on the canes indicating new leaves are about to emerge. Then prune everything down to 15-18". Remove any obviously diseased or dead canes, and any old non-productive canes. Save 3-5 of the healthiest canes and remove all others. The ideal result is a V-shape with a relatively open center. If any suckers are growing from below the grafted part of the rose, pull them off with a downward motion, to help remove any growth buds that might result in additional sucker growth. Finally, cut the remaining canes to an outward facing bud in the direction you want the growth to take.
It's okay to leave the last of the season's flowers on the bush. They develop into rose hips and when that happens it signals the plant to stop growing at to prepare for winter. Hope this answers all your questions!
