Maintenance
I like to keep my plants on the compact side. To do this, cut the new branches back 33-50% every 1-3 years in the spring. If you want a larger plant just let them grow more and prune less, but a good hard pruning every once in a while is good for the plant. Each spring there will be old dead stems to remove from the center and dead tips of branched to cut off. This plant is very thorny and a long sleeve shirt and a good pair of gloves are essential. I have found the long reach rose pruners make this pruning job much easier. Dead heading helps to promote quicker flushes of flowers. But by dead heading you will lose the rose hips. This is a matter of choice
