Although the best time to prune roses is while they are dormant, it's still early enough in the season that you can successfully prune yours back. Pruning encourages new stem growth and new blossoms. The hybrid teas should have only 3-5 good strong canes coming from the graft area. Begin by selectively removing anything that is really thin and grows straight up. Suckers like these are non-blooming. The remaining canes should be some distance from one another and look like a vase; open in the center, with canes extending from a central point all around. Then cut the canes back to 12-18 inches of the graft. New wood will form on the canes, and new stems will produce new blossoms.

The floribundas grow more vigorously and produce many new canes and stems each year. They have a tendency to be dense growers and some people use them as hedges. Cut back the previous season's growth by about one-fourth and leave as many of the strong canes and stems as possible. You'll be rewarded with many small blossoms over a long season.
