Roses will bloom well into winter, if the weather is favorable. Up here in Mich., we deadhead the floribundas, grandifloras, and hybrid teas until the middle of Sept. After that, NO pruning. It is preferred to let them set seed (hips) rather than to force them to keep growing by pruning. This is done to allow the plants to harden for the winter. After the ground just starts to freeze, the crowns should be buried in mulch, compost, soil, etc. At this time, a few long canes can be pruned back to keep from whipping in the winter winds. After the frost is out of the ground, remove soil,mulch, compost, etc., and prune back hard. If you live where the weather is more favorable in the winter, someone else will have to chime in.
