Why the Knock Out® Rose?

Snag yourself an award winning Rose that will beautify your garden space! Classically colored and re-blooming all season, these flowers will invite many pollinators, like the endangered Monarch butterfly and your busy local honeybees, into your garden space. These classic Roses pair extremely well with the dark green foliage that lasts through summer, and fades into soft hues of purple in the fall! Passerby are sure to stop and admire your landscape with an addition of the Knock Out® Rose!

The Knock Out® was cultivated by an amateur rose breeder, William Radler, in 1989. He created this Rose with the intent of disease resistance, drought tolerance, and cold-hardiness - boy did he succeed! Today, the Knock Out Rose is single handedly the most popular Rose in the United States!

How to use in the landscape?

Knock Out® Roses deserve to be the centerpiece of your garden! Plant them along your foundations, as a border along walkways, or even create a low hedge. As an extremely adaptable and hardy Rose, these will work in any space you desire!

Why Bower & Branch?

We do the hard part. Our trees and plants are grown and cared for by only the best, local growers for years before they find their forever home in your landscape. Bower & Branch is known for having hard-to-find, substantial sizes and selection. The quality of our trees and plants are consistent in health and vigor—always ready for immediate impact in your garden and instant curb appeal. We believe in empowering homeowners with the truth about strong, healthy and structurally sound plants that are grown to perform in the ground after they leave the nursery for home delivery, always fresh inventory from the grower.

How To Plant

Plant your Knock Out® Rose in a location with plenty of sun and good air circulation for success! Before winter sets in, add an extra layer of mulch around your rose to be sure it stays nice and warm!

How To Water

Water twice weekly for the first 3-5 weeks; then water weekly for the remainder of the year until winter. When you water, water very slowly and very thoroughly. The water needs to reach to the bottom of the root ball and that takes time. Watering needs may be altered due to extreme weather conditions.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late year. Continue this for three years to get your plant well established.

How To Prune

Prune your roses in very early spring once you see signs of new growth emerging. You can cut your rose back by one half to two thirds of the total size of your plant. Expect your rose to almost triple in size in the coming months.

Planting Zones

Hardiness Zone: 5-11
