It is winter hardy through to zones 5 - 10, and heat tolerant for all planting zones. This robust rose tree will flower from late spring to first frost to keep your garden full of color all through the growing season, even when other plants have stopped blooming.

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.
Select a site with full to partial sun and moist or well drained soil for your Rainbow Knock Out® Rose Tree.
If you're planting a hedge, mark out a visual guide by placing stakes five to six feet apart and looping string around them. Plant the where the stakes are and they'll grow together to make a dense privacy screen.
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.
Next, separate the roots of your Rainbow 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.
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 Rainbow 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.
