How to Grow
Light: Sun (> 6 hours sun). This encourages the best flower production while also aiding in disease resistance.
Water: For best results, roses should get about an inch of water each week, through rainfall or irrigation. This can be difficult to gauge, but if you avoid keeping plants too wet or too dry, they'll be fine. When watering roses, whether by hand or with an irrigation system, avoid wetting the foliage, which encourages leaf spot diseases and powdery mildew.
Spacing: 3 feet, minimum
Fertilizing: Roses benefit from high levels of nutrients, increasing flowering as a result. We recommend a granular rose fertilizer applied in early spring, just as the ground begins to thaw. If you wish, you can make additional applications in late spring and early summer, but do not fertilize after mid/late July.
Winterizing: In both warm and cold climates, a 2-3" layer of mulch is recommended year-round, especially in winter. In cold climates, wait until spring to prune; warmer areas may prune in autumn if desired.
Maintenance & pruning: We do recommend yearly pruning of roses, as this encourages thick, vigorous growth and the best flower coverage. Aim to cut back to just above a large, vigorous bud. The bigger the bud you cut back to, the thicker and more vigorous the growth will be. Remove any spindly stems entirely. If roses show signs of leaf spot, remove affected portions. Most roses we offer do not require deadheading, but you may do so if you wish.
Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:
Not sure just how many plants will fit in your garden? Our calculator gives you the exact amount of plants required for your space. Simply update the values and the calculator will re-calculate accordingly. Spacing information can be found in the 'How to Grow' tab on each plant's page.
Arrived quickly in good shape and has done great. Started blooming right away and hasn’t stopped, and is slowly getting bigger. All I’ve done is keep it watered. No problems; just what I wanted, and I’m very pleased!
They have only bloomed once after their original arrival.
Hello! Give them some time as they bloom in a cycle. You should have some fresh blooms soon. Thanks for leaving your review!
They are adorable. However the packaging around the bushes left a little to be desired, they looked like bare root upon arrival. Bag full of the soil. Some branches broken

The petite knock outs arrived very well packed and in good condition.
So far they are doing very well in their new home.
Much far smaller than expected. 1 year ago I order petite knock out roses from another company which rose much large in 4 weeks.
We're sorry you're not satisfied with your plants. Our customer service team would love to hear from you! On each product page and our plant sizes page, we note that all of our plants are young.

Please contact us at claims@greatgardenplants to start the claims process if necessary. We appreciate your feedback.
The plants came in fine, very nicely packaged and in good condition. I planted and watered, after a couple of weeks 5 of 6 are dying. Unknown reason on this end.

Five arrived perfectly beautiful. I kept them in the house a few weeks and today repotted 2 plants outside. I'm hopeful.
I purchased 6 Petite Knockout Roses and they arrived in perfect condition. I prefer small plants because I want to be the one raise them and shape them.
Each rose came teaming with rose buds and dark green leaves. I will definitely order more plants from Great Garden Plants again!
The plants were not up to par compared to previous ones purchased:( 3 out of the 4 ordered were in good condition. I received a replacement for the 4th plant, which was in worse shape than the one it was replacing! I was finally reimbursed for that 4th plant! I do not plan to order any more plants from this nursery!

Petite Knock Out® Rose
Plants arrived in great condition.
I loved the petite knockout roses. They are growing beautifully!
Knockout roses arrived in estimated time given. Blooming
like crazy northwest side of house. Will continue ordering
from you. Austin, Tx.
I ordered four Petite Knockout roses for indoor in our family room. They
arrived in oerfect condition and are thriving beautifully. New blooms and
buds. I love these roses, they take care of themselves and do their thing. and
we just enjoy.
plants outdoors in pots.
So far so good.
I was a little disappointed when the blossoms on my plant were fading, but now that there is new growth the color is beautiful. I still have my plant in a pot on my deck but plan to transfer it to my garden in the fall. Should I cut the plant back when I do the transfer?
Thank,you,
Carolyn DuEst
Hello! The best time to prune roses is early spring, just as the new leaves start to emerge. At this time you can remove any dead branches. You can remove a few branches to open it up if necessary. For the rest of the plant, cut it back by 1/3 in height. Make your cuts just above large, healthy buds for the best growth. We have a Q&A blog about roses that you might find helpful here: https://blog.greatgardenplants.com/questions-answered-series-roses-rosa/
Happy Gardening!
Greenery is healthy, but not many Rose buds
Hello! Thank you for your feedback. When transplanting young plants from a nursery pot to a garden, the plant allocates more energy to root development instead of shoot and flower development above ground. It's important for them to develop a robust root system so they can actually absorb the nutrients and water in the soil around them. Then after their root system is more developed they'll invest in their shoots and flower development. Keep caring for your new roses and you'll see beautiful flowers in time! Happy Gardening!
The fact that the plant is 99% dead, knocked me out
I am quite pleased with my petite knock-out roses. I waited to write this review because 4 out of the 5 rose containers ordered had bloomed with up to 4 or more roses on the branches. However 5th rose plant was slow in blooming and did not show new roses and I was concerned until this morning when I saw 3 buds that were preparing to bloom and now I am at ease. I love the roses and happy with my purchase.
These roses are adorable, bright red that changes to fuchsia over time. Very cute and grows in a 4" pot.
The roses are doing great. They grow like crazy. They are in bloom and beautiful.
Petite Knock Out® Rose
My petite knockout roses arrived a little misshapen from shipping but shaped up nicely in a few days. I repotted them into small planters for my lanai where they receive several hours of morning sun daily. They have begun flowering generously with many more buds coming. They have been as easy to care for and trouble free as my full size knockout roses.
They arrived looking good and after following your instructions were planted in large pots. They took a deer hit after a few days but now after putting deer netting over them they are growing and just this week have lovely flowers ready to bloom.
Beautiful blooms. Wish I had ordered the petite with double blooms. However, the petite roses I ordered are absolutely breathtaking.
Love the Petite Knockout Rose. It looked a bit shriveled when it arrived but had buds on it. Planted it immediately and it took off from there. Color is vibrant red & it has never been without blooms since I purchased it. This one is a keeper.
Is the petite rose the same as a mini rose?
The Petite Knock Out® Rose is a small, compact shrub that reaches about 18 inches in both height and width. It is not precisely the same as a "mini rose," which generally describes miniature rose varieties that are bred to be tiny and are often used as indoor plants or in small outdoor spaces.
The Petite Knock Out® Rose is a type of Knock Out rose developed for smaller spaces and is ideal for container gardens, borders, and small garden areas where a full-size rose bush would be too large. It's an outdoor garden plant that's known for its disease resistance and continuous blooming.
Can I keep it alive inside during the winter
Hello! It is not recommended to bring your pots into a heated space, like indoors. The reason provided is that most perennials and shrubs, which would include the Petite Knock Out® Rose, require a dormancy or chill period to grow and flower the following season. They expect to undergo cold winter temperatures, and skipping a winter season by keeping them warm indoors may stress the plants to the point of death.
It's best to keep your Petite Knock Out® Rose in a sheltered outdoor location or in an unheated space such as a garage or shed during the winter to ensure they receive their necessary dormancy period.
