Pruning Knock Out Roses

I have three pink Knock Out roses that are over 6 feet high and about as wide. I live in East Tennessee, Zone 7. When and how much can I prune them? I would love for them to be no more than 3-4 feet high. There is so much literature on pruning roses, but these are a new variety and the purpose of pruning roses is different for hybrid teas.

You can prune Knock Out roses back quite severely when they are dormant in winter. In Eastern Tennessee, Zone 7, late February or early March would be a good time to prune. You can prune all the way back to several inches above the soil line or graft union. Keep in mind that most regrowth will come from within 6 to 12 inches below a pruning cut.
