Knock out rose pruning
I have a knock out rose bush that has done amazingly well, but it's getting much bigger than I anticipated and I'm wondering if, when, and how I should prune it back, beyond the normal trim back (about 25%) I do in very early spring.

Knock out roses are beautiful and can grow surprisingly large.
The good news is they can take a pretty hard pruning, though we wouldn't take more than 2/3 of the plant off.
The time to do this is late winter into early spring, around March.
