Why do rose bushes grow like crazy but do not bloom?
You need to prune them severely in the fall and fertilize them with Cow manure..then in the spring when they start to grow prune them some more to keep of the unwanted growth.

When the roses die, cut them off you don't need all the energy going into the rose hips.



Use a good fertilizer in the spring for roses...



you will have good big roses. and lots of them.
Reply:Here is something else to consider. Most roses are hybrids. Some horticultirsts spend lots of time coming up with great smelling or looking roses but then they find that they aren't hearty enough to sell and give promising results to the public.



So, they came up with a solution. They took the part of roses that grow very well anywhere and then grafted the fancy roses onto them. So, they are really two roses in one, hence the name hybrid.



But, when a hybrid rose is planted, it's the fancy part that you want to grow, not the strong part that makes the plant hearty. I don't know how to tell you the difference but if you have never seen a bloom on the rose, it may be that the stalks are growing are the ones from the "strong" contributor, not the rose that you wanted.



Hope this makes sense.



Other than that, simple things like watering and giving it food should work.
