The Double Knock Out is about as hardy a rose as you can find and beautiful too! The reddish growth is usually normal. From that new growth emerges buds for more blooms. With all the Knock Out roses and Home Run roses you have to be careful when pruning off the spent blooms. If you prune too far down, you actually will eliminate many of what would have been new buds and blooms. When I prune mine, I prune off the spent blooms about 1/4 inch below the spent bloom. I know that leaves some little stems sticking up in the air, however around those comes new growth and a bunch of buds! The tree roses are no different. You may know already but tree roses are a grafted creation by man and are not naturally occurring "trees". I recommend watering your new tree rose with some water that has both a product called Super Thrive and a root stimulator in it. Water the rose tree with a fresh batch of this mix the next 4 to 5 times it needs water. More if you wish. It will really enhance the performance of the rose tree and other rose bushes and plants you have.
