How to Trim Knock Out Roses

Overview

Knock Out roses are one of the easiest roses to care for. They are disease-resistant and winter-hardy down to USDA zone 5. They come in colors from pink to yellow to something in between, and they can handle heat all over the U.S., even in the desert. Also, trimming Knock Out roses is a cinch since they need so little of it. In fact, Knock Out roses don't even have to be pruned every year.

Step 1

Trim Knock Out roses in the early spring or late winter, while they are dormant. Unlike other roses, you don't need to deadhead Knock Out roses after they bloom.

Step 2

Remove any dead, damaged or diseased wood from the Knock Out roses.

Step 3

Trim off new canes growing from the base of the Knock Out roses. This will keep the Knock Out roses from looking scraggly.

Step 4

Trim Knock Out roses down 1 or 2 feet. They will make up the lost growth in a season. Cut the canes above buds at a 45-degree angle to encourage new growth.
