The previous owners of my house planted a row of 6 rose bushes. One
of them is a "runt"; 1/2 the size of the others right now and never
seems to catch up. It seems healthy, just small. I know almost
nothing about roses. Is there something I can do to help it catch
up? Fertilize the small one? Cut the big ones back? I'm near
Albany, NY (whatever zone that may be).
