|When is the best time to prune a knockout rose? Mine is about 6 feet tall and too bushy.|
|Knock Out Roses take well to pruning. The major pruning should be done from December through February, but you can trim yours back now for a spectacular fall bloom. The best pruning advice is to take no more than one-third of the plant off now. Winter pruning can include reducing the size of your plant by two-thirds.
Enjoy your roses!
