Answer: The rule of thumb for hybrid tea roses is trim back to the first leaf with five leaflets, although there is some new research indicating it may be just as effective to simply nip off the flower. If you need to trim a bit more to keep the bush in an attractive shape, go ahead and do so but do not take off more than a third of the bush at a time. With the everblooming landscape roses, it may be just as effective (and a lot faster and easier) to trim them off lightly with a hedge trimmer. This may delay the flowering a bit, but it is better than not doing anything. In both cases, it is important to deadhead often. The more often, the better.
