The heights we list are after we prune your tree.

Many Nurseries advertise heights before they prune, then cut off several feet before shipping. While this reduces their shipping cost, it gives their customer a shorter tree than they bargained for. The tree will likely need an extra year to grow back the growth that was trimmed.

We prune your tree throughout its life. This process takes us longer, but gives you more branches and quicker production.

Plus, we don't include the pot or root length in our measurements. This gives you an extra 1-2 ft. in tree size.

Our larger trees are usually one to two years older than our smaller ones and will typically give you better results the first full growing season.

It's Easy to Plant your Knock Out® Rose Tree

Specific Directions for Knock Out® Rose Tree
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.

Step 1 - Dig Your Hole

Select a site with full to partial sun and moist or well drained soil for your Knock Out® Rose Tree.

First, dig each hole so that it is just shallower than the root ball and at least twice the width.

Then loosen the soil in the planting hole so the roots can easily break through.

Use your shovel or try dragging the points of a pitch fork along the sides and bottom of the hole.

Step 2 - Place Your Plant

Next, separate the roots of your Knock Out® Rose Tree gently with your fingers and position them downward in the hole.

The top of the root flare, where the roots end and the trunk begins, should be about an inch above the surrounding soil.

Then make sure the plant is exactly vertical in the hole.

To make it just right, use a level.

Step 3 - Backfill Your Hole

As you backfill the hole, apply water to remove air pockets.

Remove debris like stones and grass and completely break up any dirt clumps.

Water your Knock Out® Rose Tree again after the transplant is complete.

To help retain some of that moisture, it's recommended that you place mulch around each plant to a depth of 2"-3" up to but not touching the trunk. Organic mulches such as wood chips also help to better soil structure as they decompose.

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.

Bought 5 of these trees. The shipping container and wrapping were outstanding. Arrived in perfect condition. The trees themselves took a few weeks to settle in; but are now producing beautiful blossoms. We'll be back for more. We're in New England.

I purchased 3 knock out rose trees--the yellow, pink, and red. I LOVE these trees. This red one we had one more year than the other two so it's a bit larger--looks just like the picture! I wish I could upload pics but in any case I was very impressed with all 3 rose trees

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: The best time to prune the Knock Outs is early spring just as buds begin to break dormancy and sprout new branches. This is usually about the time the Forsythias bloom. You can also do light pruning during the growing season to keep fresh foliage and blooms coming. However, the Knock Out breeder recommends not pruning for the first couple of seasons (last year and this year) to let the bush become well established before pruning. Please refer to the package of your fertilizer tablets to see the recommended application. The rose's breeder recommends waiting a year before applying fertilizer, though it's OK if it has gone through one bloom cycle, which it did last summer. You can fertilize in spring, early summer, and mid summer, but not after that, as you don't want to encourage new growth when winter is looming. Though the fertilizer people wont' say this, from my own experience, if you have good, fertile soil, an annual feeding in spring would suffice, as well.
how should this be pruned or trimmed for winter in Maryland?
robert f on Dec 26, 2014
BEST ANSWER: Some recommend that you prune in late fall so the plant is ready to go next spring, but the introducers of the Knock Outs recommend leaving the bush over winter and pruning in spring, just as the new growth is starting.
I planted my rose tree last year & it bloomed all season beautifully. It is now May 15th & I don't have any leaves on it yet. There are new sprouts growing from the base of the trunk, but none on the branches. What should I do? Is it dead?
Judy j on May 17, 2015
BEST ANSWER: Chances are, your rose tree wasn't planted in a sufficiently large ground cavity. Nourishment has to go all the way up the cane, or stalk. If it has trouble getting it, one reason MAY be that the roots are too constricted. Keep in mind that these come without any surrounding "dirt ball" around the roots. So try to imagine a sizeable "dirt ball" being there, and THEN did your planting cavity about two and a half times bigger than that. Dig it too small, and you'll likely find nourishment isn't getting all the way up the cane -- which is why yours is putting out growth lower down. But don't take my word for it; your best bet is to contact Fast-Growing Trees and ask the experts.
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..

sandra s on Oct 11, 2014

My knockout rose trees has holes in the leaves. It this a disease? What can I do?
A shopper on Jun 8, 2014
BEST ANSWER: If the holes are perfectly round or nearly so they are probably the result of cut bee activity. This is an annoying, but not plant threatening pest!
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.
sun or shade?
A shopper on Jun 13, 2014
BEST ANSWER: I planted in direct sun and it is doing great!
Do they have thorns?
A shopper on Jul 19, 2014
BEST ANSWER: Yes but they are somewhat smaller then the ones on the bushes. cheers john
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!

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!

Will my plant be eaten by deers?
Angie N on Sep 17, 2014
BEST ANSWER: No, spray small amount of water & dish washing soap on tree & it will repel all pest & fungus. Blooms so much & we enjoy ours so much --we went back & ordered a 2nd one. :) Worth every cent! Yes, pricey, but in the long run you will save money not having to replace the plants. Awesome & everyone in neighbor hood enjoys our rose trees. Many have bushes, but they aww over our trees. Great investment & will not disappoint you. Also put cracked egg shells around the base of the tree when you can. You will be shocked! Beautiful!
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.
How tall and diameter will they grow to at full growth?
John J on Jun 28, 2014
BEST ANSWER: The Knockout Rose Tree grows between 4-7 ft tall, and 2-3 ft wide.
what to do if white powdery spots appears?
A shopper on Jun 27, 2014
BEST ANSWER: If white powdery spots appear you have a few options. 1. Take a moist towel or paper towel and see if you can remove the residue. 2. wipe the tree down with a soap and water solution with 3 parts water and one part soap. Use a gentle soap like Dawn. 3. Spray your tree with an organic fungicide. 4. Remove any parts of the tree that have the residue.
I put my tree in an unheated garage over the winter and in spring, it was budding very nicely. I trimmed the branches to even it out and now it looks as if it's dying. What can I do?
Sherri B on Jun 21, 2014
BEST ANSWER: It could be going through a blooming cycle. It cycles through blooms every 4 to 6 weeks. I would suggest giving it some fertilizer. Follow the care instructions on the link below closely.

Can I purchase this tree now, keep in my sunroom over the winter then plant in my landscaping after no danger of frost?
Heather W on Oct 5, 2015

A bit early for this question but I am wondering.... When preparing for winter in Wisconsin, does a knockout rose tree need to be mulched in fall? If so, how is this done?
kim r on Aug 4, 2015
BEST ANSWER: Yes you will want to do a heavy mulch as it starts to really cool off in your area. We have a great blog about winter protection for your plants. Our favorite is 3 to 6 inch layer of mulch.

I live in zone 6. So, this tree can be planted in the ground and should continue growing year after year? How does it keep the shape of a tree?

Will my Trees Look Like the Photographs?

Most trees and plants on the website are pictured in their mature form. Depending on the product and growth rate, mature development can take years for your plant to resemble the photos.

Picture the last time you took a walk in the woods. The young trees were not miniature bonsai versions of mature trees. Instead they were naturally thin and lanky. Young trees are programmed to race toward the light, before the competing vegetation crowds them out. Once established at 10 feet or more, they start developing a wide canopy and shedding lower limbs.

Most Trees and Shrubs are Pruned Before Shipping... at No Cost to You

Tree before pruning Tree after pruning Rose before pruning Rose after pruning
Maple Tree before pruning Maple Tree after pruning 3 gallon Knockout Rose before pruning 3 gallon Knockout Rose after pruning

Pruning makes plants appear to be less-full than the ones you may have seen at your local big box garden center. A retailer's goal is to have plants look their best while sitting in the store. Our goal is to have them look the best after you plant them.

Pruned trees and shrubs not only travel better, but become established much quicker. So rather than supporting extra foliage, they put their energy into sending out deep roots. Once that happens, your plants become hardier and quickly explode with new top growth. Above the ground, pruning helps your plants develop a more attractive form.
