You can't go wrong with the new Sunny Knock Out® Rose Tree in your landscape or flower garden! This tree has all the qualities that have made the Knock Out® series of roses the #1 choice of homeowners and landscapers across the country. You'll get amazing yellow blooms for 9 months!
From April until frost, this tree will provide beautiful full yellow blooms.
A significantly tough rose tree. It is very low maintenance and extremely adaptable to many regions and soils. It does well in Zones 5-10. Be sure to give your Sunny Yellow Knock Out® Rose Tree full sun and good drainage. It will thrive on its own with little attention once established - and will sail through dry weather quite nicely when in the ground. If you're growing in a container, you'll want to water it regularly. (No worries, we provide easy to follow instructions.)
The compact size and naturally rounded shape of this Sunny Knock Out® Rose Tree makes it a perfect fit for any spot in your yard - or on your porch or patio. Masses of bright yellow blooms provide breathtaking natural beauty - whether planted in the ground or in a container.
Established Roots for Fast Growth
Roses initially grow rather slowly, so for instant beauty and an easy transition to your yard or container, it's essential that you purchase a plant with an established root system. That's what we offer. You'll soon be rewarded with months of colorful blooms. You'll enjoy an instant impact for your yard and garden rather than waiting years to see results. Easy to own, there is no need to clip your Sunny Knock Out® Rose Tree to shape it. Watch our video on why we don't ship Bare Root. (Your rose tree has been nurtured and will be delivered healthy and ready to perform.)
We prune your Knock Out® Roses before we ship them out to give you an explosion of growth when you receive them. Order Now.

Customer Reviews & Photos
Beautiful when fully blooming
I needed a little something for a fairly stark rock bed and the knock out rose trees were the perfect choice. They came well packaged and arrived quickly with easy planting instructions. I hope they survive the summer heat as it is clear they prefer slightly more gentle temps than the triple digits we had this week. But then who doesn't?
Yellow Rose Tree
Received in April and started blooming right away. It is not as bushy or thick as the Red Rose tree we also purchased but hopefully it will continue to grow.
A REAL BEAUTY
THIS ARRIVED IN BEAUTIFUL CONDITION AND NOW PLANTED IN A SMALL ROCK GARDEN ITHAS MANY BUDS AND YELLOW ROSES.
It's doing great
After a month from planting it looks great and blooming like crazy! Would certainly recommend buying through this vender. Thank you!
Ordered 2 of each color knockout. The yellow came with some blooms which were gorgeous. Great shipping and packaging of the plants as well.
Planting & Care
A Knockout Rose tree is an ideal landscape tree where the desirability of the classic rose form can be incorporated into a structural arrangement with the benefit of that of a common tree. The Knockout Rose tree is an upright tree which forms a tidy mound 3 to 4 feet high from the base and blooms from June until the first hard frost. Knockout Rose trees and Knockout Rose shrubs complement each other well when planted together.
Knockout Rose trees look best planted in groups of three or more and can be planted to form low rise hedges. They also make for good feature trees when planted alongside Double Knockout Roses. Last year alone, some 3 ½ million Knockout Rose trees (of which many were Double Knockout Roses) were sold making them a very popular choice amongst gardeners.
Seasonal information: They are upright shrubs that form a tidy mound 3 to 4 feet high and bloom from June to the first hard frost. In spring, trim any broken or dead branches. You can shape the Knockout rose at this time. In zones with cold, wet winters, give your Knockout rose winter protection by planting on the leeward side of buildings or walls. Or you can wrap snow fencing loosely around the rose and cover with straw.
Location: Select a well-drained site in full to partial sun. If you choose partial sun make sure your roses receive at least six hours of direct sun a day (afternoon shade is better than morning shade). If you have clay or sandy soil, work well-rotted manure or compost into the planting site.
Planting instructions: Space three feet apart if planting multiple trees.
1) You should start by digging a hole twice as wide and twice as deep as the root ball.
2) Mix the manure or compost with the soil you have removed.
3) Back fill the soil until you have a hole the same size or slightly larger than the container the rose is in.
4) Plant the rose at the same depth as it is in the container.
5) Mulch around the base of the tree to keep competing weeds and grasses from growing.
Watering: Keep Knockout Roses moist at all times. Water around the roots rather than overhead. Mulching will greatly assist with soil moisture retention.
Fertilization: Fertilize with an organic rose fertilizer once a month. Use organic fertilizer rather than synthetic fertilizers as synthetics can promote weak growth and your rose will have more foliage and less flowers. Even though Double Knockout roses are disease-resistant, they still need adequate air circulation, created by properly spacing plants.
Pests and Disease: Knockout roses are resistant to rust, black spot and powdery mildew.
Pruning: Avoid pruning the Knockout roses at all in the first 2 to 3 years. Sterilize your sharp pruning shears with hot water or rubbing alcohol. This guarantees a cleaner, healthier cut. Always prune at an angle and not straight across. Activate the Knockout into growth and blooming by pruning it back a little in the spring after the last hard freeze. Keep the rose under control or if you want it smaller than it's 3-feet wide by 4-inches tall size by pruning it back in the late summer or early fall. Remove dead or old canes at any time. Also cut very thin canes that might be coming up from the ground. Prune your mature plants by using the 1/3 rule each year in the spring. Remove 1/3 of the oldest canes and any stems that are damaged, diseased or dead.
