    The benefits of the Drop ‘N Grow™ bag…

    By growing these trees in burlap bags, the roots grow into the cloth, rather than circling around a pot. This forces these trees to put out thousands of fine hair roots. These roots bring moisture and nutrients into the plants. This means you get a tree that will become established quicker and provide you with superior and faster growth.

    These will be the easiest trees you have ever planted! Simply dig your hole, place the Drop 'N Grow™ bag in the center (burlap included) then use excess dirt to fill the hole. That's it!

You just can't go wrong with any Knock Out® Rose in your landscape or flower garden!

The new Sunny Knock Out® Rose Tree has all the qualities that have made the Knock Out® series of roses the #1 choice of homeowners and landscapers across the country. It is very low maintenance and extremely adaptable to many regions and soils- which is why it is so popular!

Very Tough- Just Like all the Other Knock Out® Rose Trees
But now you have a wider variety of bloom colors with sunshine yellow to add to the mix. Your Sunny Knock Out® Rose Tree will pump out luscious flowers from late spring til late fall in great abundance.

Better still, the compact size and naturally rounded shape make this new rose tree perfect for any spot in your yard, porch or patio.

Smothered with Bright Yellow Blooms
Looks great when planted either in the ground or in a large container... as long as you give your Sunny Yellow Knock Out® Rose Tree full sun and good drainage. It looks great, even with very little maintenance.

Once established, your new rose tree will sail through dry weather quite nicely when in the ground. However, when grown in a container you'll want to water it regularly.

For the Best Results, Plant Quality Rose Plants
Roses grow rather slowly, so for instant beauty and an easy transition to your yard, be sure to buy Knock Out® Roses in large pots for that established root system. You'll soon be rewarded with months of colorful blooms. You enjoy instant impact for your yard and garden rather than waiting for a year or two to go by - or having to keep clipping to give your Sunny Knock Out® Rose Tree a great shape.

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

Sunny Knock Out Rose Tree
I am very pleased with my rose trees they came on time and they were well packed, in fact I was really impressed with the packaging not a drop of soil came out of the pots. I planted one on each side of my front stairs and they are doing very well thanks to your potting mix.

Planting & Care

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

Sunny 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.

My son bought me a beautiful red knock out rose tree when my dog died two years ago. It kept blooming all summer, but, didn't come back after winter. I want to try again. What do I do differently? I live in zone 5
Debbie C on Apr 25, 2015
BEST ANSWER: I live in 7 but if you have snow/ice, I would think you'd need to cover them during cold spells. I suggest going to a local nursery and asking for advice on your area.
what is the best pot size for knock out rose trees? I plan to keep it in the container year-round in zone 5.
Michael on Mar 21, 2015
BEST ANSWER: I planted this in a 15in deep urn style plantar recently and it's growing strong.
How big a container is this?
A shopper on Jun 26, 2014
BEST ANSWER: They were about 2.5 to 3 feet tall. I planted my trees in the ground. They are about 4 feet now.
Does the rose brush attract bees?
Cynthia M on Mar 30, 2015
BEST ANSWER: No. Knock Out rose, do not have an intense fragrance and less nectar than other flowers. They also restricts access to the inner flower were the pollen is stored.
A shopper on Jul 14, 2014
BEST ANSWER: I live in Seattle where the winter is fairly moderate, only occasionally getting to 30 degrees. This tree is on my 8th floor patio, the top floor. what is odd to me is that we have the Sunny Knockout bushes one floor above, on our Community Roof Garden, and they seem to be very hardy. The tree on my patio is constantly sprayed, however it has rose rust etc. and does not seem to be as hardy as the bushes.
I see I can plant this in a container. Do I have to bring it in, in the winter? Is it fragrant?
martha l on Jun 23, 2015
BEST ANSWER: If you live in zone 6 or south, you can leave the container outside. If you live in zone 5, you should probably provide protection for your container as the roots are above ground and more prone to freezing than in-ground plants. You can also keep an eye on the weather and roll your plant into the garage or a shed during cold snaps.
does the yellow rose stay yellow or does it turn white?
Jim D on Mar 21, 2016
BEST ANSWER: Jim, my yellow rose tree stays a bright yellow all thru the blooming season and one other thing I've not experienced it turning a dirty look as the bloom dies which has impressed me. Hope this helps
Can you plant this tree in a pot?
Ken F on Apr 25, 2017
BEST ANSWER: The pot needs to be much bigger than the roots. You'd have to overwinter it in a shed or garage.
does this need pruning or do the dead leaves fall off on their own like the pink knock out tree?
Karen W on Jul 6, 2015
BEST ANSWER: Karen, all three of the rose trees that we purchased are doing great and the only thing I do is to cut the dead roses off when they have completed their bloom cycle, during the winter time they do gradually loose they leaves but in the early spring they have come back with a much fuller tree and more roses. I hope that this helps you and I plan on buying more because I love them.
Is there anything we can do to keep the brighter yellow of the roses?
Cindy H on Mar 8, 2017
BEST ANSWER: It might help if you keep them in a shady area in the afternoon sun.Enter an answer to this question.
Why do my bushes have some yellow leaves on the bottom of the bushes?
June H on Jul 26, 2016
BEST ANSWER: Too much water, lack of nutrients, hot and cold weather changes can cause yellowing of leaves. It could also be the normal cycle of life. If the foliage get to thick then then leaves will fall off to promote a better air flow.
If knock out rose tree is in a container, can it be brought inside to a garage for winters in Illinois or Oregon?
Barbara S on May 27, 2016
BEST ANSWER: I would think so as long as it doesn't get too cold in the garage.
What does this look like in the winter? Does it have leaves all year long or is it bare in the winter?
Steve B on Aug 18, 2014
BEST ANSWER: It is bare in the winter!
