What is with these roses??? I live near Portland, OR, and have four bush roses planted about 2 or 2 1/2 feet out from the wall. They were pruned very close for winter, but the wall side of two of the four has grown thickly and toward the wall, while the open side is sparse and not as healthy looking. Isn't that backward?? They are on the south side of the house, which is yellow. Does the sun's warmth and light reflected off the house cause this? Those two rose bushes are now growing up the wall, although they are not climbers. I've never seen this before. What is it? Why don't all four do it?
Thanks for your help.
