RoseBlush1 said: The second is that if you did not dead head the rose and allowed it to form hips, the plant "thinks" it has completed its primary function of continuing the species and has set seed and doesn't need to bloom any more. If you see any rose hips on your rose, I think you should just nip them off and not allow them to ripen and this sends a signal to the plant that it has to start and produce blooms to attract the pollenators to help fertilize the bloom so that the plant can set seed and complete the plant cycle. That is why we dead head the roses.

Note this isn't universal. May be more of an issue for those in lower zones but I'm in the equivalent of z10b or z11 (Sydney Australia) and many roses here don't slow down despite the lack of dead heading (i don't dead head, seeds for growing) Granted I don't grow many HT's so the reputation may stem from those as they do slow down for me compared with minis, floribundas.
