Q.My Rose is growing healthy but it’s not blooming
All my other roses around this rose are blooming; however, this particular rose looks healthy, growing unreal but not one flower. Could it be possible that this rose is a blind shoot all over? I have only had this rose for 6 months!
Right off the top it sounds like it could be one of two things. One is that the fertilizer being used is too high in nitrogen. High nitrogen fertilizers make for super growth and rich foliage but causes either limited or no blooms. If the rosebush is an older rose (which it does not sound like it is), it is possible that the original and desired rosebush has died and the root stock has taken over. The hardy rootstock will grow big and rapidly, sometimes not flowering at all or not flowering until its 2nd year of growth. Here are some links to articles that should be of interest to you on this:
