It's Easy to Plant your Rainbow Knock Out® Rose Tree

Specific Directions for Rainbow Knock Out® Rose Tree

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 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.



Step 2 - Place Your Plant

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.

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 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.

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.

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

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.
