Trimming Knockout Roses
When do I prune my Knockout Rose bush?
Prune your rose bush in Late February or early March, never in the fall and never in the
winter.
How much should I cut my Knockout rose back?
Basically you can cut your rose to most any height. A Knockout Rose will usually grow
two to three feet in a single season, so keep this in mind when determining how far back
to cut the rose in early spring. Example, lets say that I cut my four foot knockout rose
down to one foot at the end of February, I can expect the rose to grow back to a height of
three to four feet before the end of summer.
