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

Specific Directions for Sunny Knock Out® Rose
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 Sunny Knock Out® Rose.

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 Sunny Knock Out® Rose 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 Sunny Knock Out® Rose 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.

Growth Rate
A great addition to any garden,
These tiny bushes arrived in good health and were planted in full sun, in NC. This is the second year for two of them, and I needed to add just one more. In their first year the growth is slower but so many flowers it amazed me. You need to deadhead the spent flowers to encourage more blooms. They bloom from June to frost - Hardy and true.

knockout rose and fig tree
They r both doing extremely well. I am convinced those roses will do well under any circumstances. They have survived beetles,aphids and drought. No I have sprayed them and fed them. They r so pretty. The fig tree is 2 ft. tall and had figs already. The squirrels ate them. Everything I have purchased from u has been exceptional.
Thanks, Beth

It's an odd plant the flowers die than they regrow, many many times over. I've planted them in clay and they have no trouble growing in it even with the heavy and constant rain. They can handle Maryland Winters.

Fragrant and very pretty roses
This was the first time I saw a "yellow" knock out rose bush offered and was surprised it had a fragrance. I already had quite a few pink knock out buses and they are wonderfully carefree. Am looking forward to enjoying these too. They arrived promptly and some already had buds on them. All 6 bushes are growing well and have flowered. Very happy with my purchase.

A Tribute to Wilson
Wilson was the grand cat of the Cat Hospital of Tidewater who recently passed due to tumors. One of the assistants took him home to bury him. I donated the Knock Out Roses to his gravesite, but have not seen them. I did ask how the roses were doing and I was told fine. I'm sorry I can't give you a better write up.

Product in poor shape, barely alive when recieved. Forget blossoms, just trying hard to survive, which is being done.
Rose must have great root system and 'will to survive', altho
it looks puny, at least it still has a few living stems & leaves,
now that I've babied it for last month.

what times of year are ok for planting knockout roses?
bill s on Oct 28, 2014
Best Answer: You can plant a potted rose pretty much any time of year, except when the ground is frozen or the temperatures are over 90 degrees Fahrenheit. If you plant in warm weather, you will need to be sure to keep your plant evenly moist and not let it dry out, though its location should have good drainage to keep it from getting boggy. Of course, planting in early spring is best if you have a bareroot plant.

About 3 weeks ago, I purchased a bright pink knock out rose plant. It is still in the container since I am trying to decide where to plant it. I have never had one before so I am not quite sure how to care for it. I see where someone on here said you can leave these plants in containers. Won't it die if the roots don't have enough room to spread out for the plant to grow? Or do you have to keep re-potting it. Also, the flowers on my pink knock out rose are very similar to the sunny yellow one pictured. Is that the way they should look? Is it better to plant them or leave in containers? Also, when should they be fertilized? Some say at the end of August, other say in late fall.

My red Knockouts bloom incessantly all year, but the blooms on my yellow roses only last a day before they start going backwards. Is this normal for a yellow Knockout rose?
A shopper on Sep 14, 2014
Best Answer: My yellow knockouts don't seem to bloom like the red or pink ones; those just seem to bloom and bloom, where my yellow bloom like crazy initially, and then stop for a couple of weeks, then bloom again. Why?

I have a yellow knockout rose bush and the leaves are being devoured by a pest. How do I stop this?
Tom C on Jun 27, 2015
Best Answer: First, you need to figure out what is eating your rose's leaves. Without a picture or description, it is hard for us to give you definitive advice, however, you might very well have Japanese beetles, which absolutely love roses. To control them, take a bowl of soapy water out in the early morning and late evening, when they become sluggish, and simply knock the pesky beetles off the branches into the bowl; or you can dust your bush with Sevin. Your pests could also be caterpillars, Fuller Rose Beetles or a number of other insects, which would require other steps for control. If you can't figure out what is eating your bush, we recommend asking your County Extension Agent for help!

Are they deer resistant?
A shopper on Jun 29, 2014
Best Answer: No plant is 100% deer resistant. If a deer is hungry and food is sparse they'll eat anything. Sunny Knockout Roses aren't the first choice for deer, but if deer are prevalent in your area and have caused problems in the past I would recommend spraying your roses with a deer repellent spray.

Do they smell nice?
marie h on Jul 2, 2015
Best Answer: not really, which is why I had intentionally bought the yellow (versus the pink or red) but they were healthy plants when they arrived, are still beautiful, and have grown nicely. They should stop saying that they have a scent, however, because if they do, none of us can detect it. The other odd thing is that they bloom like mad, then quit for a couple of weeks, and then bloom again, where it seems to me the pink & red just keep blooming and blooming, I don't notice those "quit" for a few weeks and have no blooms.

how big do the sunny knock out roses get?
Berta I on Oct 26, 2014
Best Answer: Hello Berta,
The Sunny Knock out Rose will grow as big as you want, usually around 3 to 4' round. once it has been growing for a few years. I trim my roses back in the spring down to about 1 1/2'. Use garden gloves.
You would be very happy with the shades of yellow this plant gives, trim off the old rose buds during the summer to fall mounths. Enjoy

Should Sunny Knockout roses be pruned?
Meg R on Aug 20, 2014
Best Answer: I have no idea. I pruned mine (not to the ground, just to give it a shape) and its bigger and bushier than ever. I got mine last year. It blooms constantly and I cut the spent blooms off. It starts blooming in May and went til November last year and even made it through the first few frosts, blooming continuously! It's a great plant.

Will my Trees and Shrubs 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 dormant trees shipped in the
late fall through spring arrive bare root

Bare Root trees are shipped without dirt or any green foliage showing. Some customers who have never planted bare root before, think that they received a "dead stick" with roots. These dormant trees are basically sleeping over the winter as most trees do. Because of their hibernation-like stage, this is a great way to transplant these trees. Since a bare root tree lacks foliage, they need very little moisture.

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.
