Pruning Knock Out Roses for Shape and Vigor

Pruning Knock Out Roses for Shape and Vigor

In Zone 4, three-year-old Knock Outs that are lanky and wind-burned need spring pruning.

Simple Method

Cut entire bush horizontally to 18 inches tall.
Plant will regrow to 3 ft with rounded form.
No precise cuts needed—Knock Outs are forgiving.

Why It Works

Removing dominant tall canes allows basal breaks, creating a fuller plant. Prune annually to maintain shape.
