FAQ: Should I prune my Knockout roses this time of year? They have grown too big.

I understand that you are concerned about the appearance of your Knockout roses, but I advise you to wait. Pruning stimulates new growth. New growth is easily damaged by freezing temperatures. Now it's late October, so cold weather will be arriving soon, if it has not already, in most parts of the country. If you live in a mild climate such as south Florida, you may prune Knockout roses now without much risk of damage. However, if you live in a colder climate, you should wait until spring when danger of freezing is past.
