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 Knock Out® Rose in the landscape?

How To Plant Knock Out® Rose

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

Newly planted Roses should be watered every two or three days, once Roses become established water them once or twice a week as needed to keep the soil moist.

How To Fertilize

Feed your Roses twice a year in March/April before flowering to encourage bigger and colorful blooms.

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.

How Does Shipping Work?

Bower & Branch Trees, the real BIG trees, don’t fit in a box! Our big trees, sizes XL and bigger, require expert delivery and care, that means our extra-large trees are shipped on Bower & Branch trucks. We are the only ones who know how to ship our big and bigger trees and plants with tender loving care. We deliver your trees and plants directly to you. Ask Bower & Branch about planting services – we'd be happy to assist in installation.

*For Big trees and Shrubs, Size XL and bigger: Review our Seasonal Shipping Timelines and Policy here.

Your trees and plants are grown across the United States at various Bower & Branch Growers. Depending on your location, your plant orders may be shipped from various locations. Please expect orders with multiple items to be delivered over a number of days as a result. Orders made up of numerous items or selections will not arrive at your home on the same day.

Shipping Delays:

From time to time, Bower & Branch Growers may determine to delay order shipment based on various factors for plant health. Weather in your region, as well as, where your plants are grown, is always considered when shipping. Extreme weather conditions may delay some or all of your order. Bower & Branch allows our Growers to make final shipping decisions based solely to benefit your trees and plants’ health and success.

How Does Sizing Work?

The size of our trees have nothing to do with the container size like you may find elsewhere–big doesn't mean just height - it’s also vigor, age, and overall health. Other online retailers are going to tell you that a plant is a seven gallon, that means nothing to your tree or plant (or you.)

Our trees for sale online are graded on large, x-large, and even bigger sizes. This is because our trees are sized by their age—the higher the letter, the more mature the tree. The age determines the trees’ overall height, size of the trunk and the overall branch density.

All of these characteristics are what you should be looking for when choosing a tree for immediate impact and instant curb appeal. Our extra-large tree and plant sizes are sure to wow you and your neighbors!
