How to Use Sunny Knock Out® Rose Tree in the Landscape
The sweet little tree has such pretty yellow blooms and keeps roses growing all through the season. People notice it right away, so use it where you want to draw attention.
If you have the room on your porch or portico, place one on either side of your front door in large, exterior pots for a sophisticated, yet cheery greeting. They’ll appreciate the yummy citrus scent as they approach your home.
Use a single tree in your foundation planting as a small accent near the front walk as a welcoming beacon for your front entrance. Plant in the ground, or use a fun container to coordinate with the exterior finishes of your home.
Underplant the tree with spring bulbs, perennials and groundcover for a textured look that works beautifully throughout the season. Add short, dwarf evergreens to extend the interest over winter.
They’ll make the perfect plant to decorate your patio outdoor entertainment areas. They look fetching in pairs flanking an entrance, or try an odd number placed in a curve behind seating areas.
March a series of them down the length of a garden path to add structure and charm. Or, try this same look as a lovely backdrop for perennial gardens.
For a marvelous look, try using 3, 5 or 7 of these trees as regular punctuation through a long hedge of Sunny Knock Out Rose bushes. Adding the trees brings vertical height to your hedge to easily increase the dramatic impact.
Increase the formality with a disciplined planting plan. For instance, you can plant 3 bushes, then add a tree, then 3 bushes, then a tree and so on. Start and end with bushes for a nice finishing touch on either end. It will look like a million bucks, but the low maintenance level of care stays the same.
#ProPlantTips for Care
Choose a well-drained site for planting in your garden. Rose root systems won’t tolerate wet soil. If you see puddles that last a long time where you hope to plant, you can “mound up”. Add additional soil to a height of 18” and plant directly in the mound.
Elevate containers up off the ground. Use 3 or more bricks in a wide triangle to give a steady base. You want to position the drain hole over the opening in that triangle. Rose trees grown in an outdoor container should not have a saucer underneath, please. Keep the soil drained.
Sun loving Roses perform at their best in full sunlight. Knockout roses in particular are able to handle long, hot days spent baking in the full blaze of the sun. 6 - 8 hours of direct sun are recommended.
New plants will require a moderate amount of regular water to get their roots established in your native soil.. Test before you water by using the “Finger Test” by poking your finger into the soil up to the second knuckle. If it’s getting dry, time to apply water. If it’s still moist, you can skip watering that day. (Pro Tip: use the Finger Test on houseplants, too!)
Knock Out Roses will display drought tolerance once their roots are well established. However, we recommend you baby your Tree Form plant a bit, especially if you are growing it in a container. Set up a drip irrigation system on a schedule to keep things really easy for yourself.
While not required, you can give a balanced Rose bloom fertilizer twice a year, following the directions on the label. Usually, it’s recommended to wait for the first application until after the first flush of blooms are passed. Give the second application no later than mid-summer. Each formula will have different application rates, so be sure to check the instructions.
Knock Out roses are well known for their rugged nature, and disease resistance to black spot, rust and powdery mildew. Give your tree plenty of sunlight for the best results. Diluted organic Neem Oil can be sprayed on the foliage in the evening, if you ever feel like it’s needed. Chances are great you’ll never, ever need to worry about it.
You’ll want to study your tree in early spring once the new growth is leafing out. Remove any crossing, damaged, or “wild” canes that have a mind of their own all the way back just above a new bud.
Make selective pruning cuts to open up the interior of the canopy for more sunlight and air circulation. You can also hard prune the entire canopy back with tip pruning to control size, if desired.
If you’re looking for a happy-go-lucky, easy care Rose with a fresh, modern twist, the Sunny Knock Out Rose Tree is for you. You’ll feel like you captured the sunshine with this pretty selection. Don’t miss out on your chance to own one of your own, order today!
