All the Gorgeous Color and Easy Care of the Knock

Rich blooms in abundance with no maintenance needed!

Knock Out® Roses have set the standard for bloom color, size, and adaptability.

Now, horticulturists have bred a tree with the same characteristics! The Knock Out® Rose Tree has raised the bar for disease resistance, and is as carefree as they come. Hardy and reliable, your rose tree will bloom from early spring to first frost, giving you fluorescent blooms for months.

This self cleaning rose tree requires no dead heading. Other roses require you to prune off the dead blooms so that new ones will grow. These blooms simply fall off when they start looking undesirable.

Your Knock Out® Rose Trees come pruned to promote more branching. More branching means more blooms!

Disease resistant, even to Blackspots that harm so many other roses.

Adaptable to various soil types and drought tolerant, too! Reaching a mature height of 4-7 feet, your Knock Out® Rose Tree will work in any area of your landscape.

Plant in containers or directly in the ground. Creates a stunning entryway, pool accent or garden focal point.

A versatile tree that stays smothered in roses for up to 6 months out of the year.

We prune your Knock Out® Roses before we ship them out to give you an explosion of growth when you receive them.

This is the hottest rose introduction in years. These trees will quickly sell out, so order yours now.

This EXACT same rose tree sells at Lowes for $30 EACH. This is NOT a $100 rose tree, as I was promised by Fast Growing Trees when I ordered it. They are small; slow growing!! Disappointed!
December 31, 2012
It is a beautiful tree, very hardy. We have had great blooms each year and the growth is incredible! However, after any given rain you can expect that your tree will be bent over from weight- VERY top heavy. We had a particularly heavy rain recently and found the top of the tree laying on the ground (happened twice). Must be staked/ stabilized

My Red knockout Rose Tree is a knockout. I put it in a container on my deck and it is BEAUTIFUL!!! I thought this was the same tree I saw at Lowe's. Boy, was I sadly mistaken. I have one in my front yard and the other on the back deck! Very happy with my purchase. Thank you!!

I purchased 2 of these last summer/fall for my mother and planted them for her. A local nursery had informed after the fact to not expect rose trees to live past winter. Well... it's well into spring now and these from Fast-Growing are both doing great so far.

Planting & Care



It's Easy to Plant & Care for Your Knock Out® Rose Tree


Knock Out® Rose Tree Planting Diretions Your Knockout Roses will thrive in an area the receives full to partial sunlight, and prefer six to eight hours of sunlight a day. Afternoon shade will be more beneficial for your Roses than morning shade.

Your natural soil will be great for your Knock out Roses especially if it's well drained, and isn't too light or sandy. Keep your soil moist, not over saturated. To help hold the moisture in spread mulch around the base of your Knockout roses. Knockout roses prefer to receive water at their bases instead of receiving water from overhead.

You'll see blooms on your Knockout Roses early every Spring, that will last until your first frost. Knockout Roses produce new blooms every four to six weeks and will love it if you give them organic fertilizer once a month after their first blooming cycle.

When should we prune our rose tree how how often do we add the fertilizer pellet/tablet to the roots? We got the tree around August 2014. Please advise. Thank you!
The Guys on Jan 25, 2015
Best Answer: Avoid pruning the Knockout roses at all in the first 2 to 3 years. Sterilize your sharp pruning shears with hot water or 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.
Fertilize with an organic rose fertilizer once a month. Use organic fertilizer rather than synthetic fertilizers. Synthetic fertilizers 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

How far does the root system spread when planted in the ground?
M W on May 8, 2015
Best Answer: The roots will spread about as far as the foliage, which is 3-4 feet. They might extend a little farther as the plant matures but rose roots are not aggressive and fit in with other plants quite well..

My knockout rose trees has holes in the leaves. It this a disease? What can I do?
A shopper on Jun 8, 2014

Can these roses grow indoors?
jeremy r on Apr 21, 2015
Best Answer: The rose tree would probably STAY ALIVE indoors -- with enough artificial sunlight -- unless it was inside some sort of greenhouse or hothouse. But merely staying alive is a far cry from GROWING. Moreover, it should be kept in mind that the root ball expands as the rose tree grows. I doubt it would respond too well to constant changes in the pot or planter it's planted in. My advice: Keep it outdoors where it belongs.

Could I grow roses in a container?
A shopper on Jun 1, 2014
Best Answer: You sure can. So long as the pot gives ample room for the roots. Roses will deplete soil nutrients more readily in a pot then they would in the ground so watch for that. For a starter, be sure the pot is no smaller than 15" diameter. Then plan to transplant in two about two years.

i planted one of these about a foot from my house and its gotten pretty big will it interfere with the foundation of my house>?
Michael A on Jun 29, 2015
Best Answer: Though rose roots probably won't do much damage to your house's foundation, a foot is too close to give your rose room to grow and look its best. The top will spread to be about 3 feet across, or about 1 1/2 feet from the stem, so your rose tree needs at least 2 feet of clearance all sides just to accommodate the plant, and more to keep it from crowding your house. A further benefit of giving your Rose more space is that it promotes good air circulation, which helps keep your plant disease-free.

I recommend that you dig up your rose tree and move it a minimum of 3 feet from your house, and 4 or 5 feet might be even better, if you have the room. Allow plenty of room for the root ball when you dig, making your cut around 12-18 inches from the trunk all the way around, and making the hole you move it to a foot or more bigger than the root ball. Best time to do this is in late winter, when the plant is dormant, but it can be moved when in active growth if you are prepared to make sure it has plenty of water.

Good luck with your Rose Tree, and I hope it gives you many years of enjoyment!

t live in Kalamazoo Mi. The area near my house gets shade to partial shade till 3 pm and full sun 3pm till 7pm. Will that be enough sun for knockout rose trees? Also, our winters can get pretty darn cold 2014 winter was harsh. Is there a way to protect them from harsh winters?
brownthumb? on Aug 4, 2014
Best Answer: I think the reverse of what you get (e.g., full sun for 4 hours in the MORNING) would probably be better.
But these rose trees are pretty sturdy, and those 4 hours in the afternoon likely will still work for you. As to winter protection, the big thing is the stalk, or "cane." I use foam pipe wrap (it's cylindrical in shape, but with a cut down it). Simply put it around a growing cane, then either tape it closed, or you can use soft rubber plant ties to do it. Think of "pipe wrap", only not as tightly applied.

Do these trees survive in zone 6? I have had 2 local nurseries tell me they die in this area. I am in North Idaho.
dancnfish on Apr 4, 2016
Best Answer: Based on the growing zone map, it sounds like they may survive in Zone 6. I live in Denver (zone 5) and the rose tree I bought two years ago has died (probably due to a couple of freezes). I did not plant it in the ground but in a large planter, which may have made it susceptible to the elements. I recently bought another rose tree for this spring (to be in planter again) - sure hope it survives through the winters. I may need to follow the planting instructions more carefully though.

Can this tree survive Massachusetts cold winters? I bought one at Home Depot and it died.
Donna K on Aug 28, 2015
Best Answer: Am not certain about how low the temperature would have been in Mass. but the Knockouts that I have survived just above zero and up into the low 100's. Think if the roots were ;mulched extremely well, the bush would probably survive even if you had to prune the bush in the Spring. They are great roses -- good luck!
