How to prune double knock out rose

Late winter to early spring when new shoots begin to emerge on canes. Cut all canes back to 12–18 inches. Remove dead, damaged, and weak stems first, then reduce remaining canes at a 45-degree angle above an outward-facing bud. Avoid any late-summer pruning that could stimulate tender growth before winter.

Reduce to 12–18 inches depending on your climate. No deadheading is required — spent blooms drop on their own — but you can remove them for tidiness.
