Overview

Double Knock Out roses are one of the more drought-tolerant, low-maintenance roses available to grow and enjoy. They possess the characteristics of old-fashioned roses but have the ability to resist many of the problems associated with some roses, such as black spot. The Double Knock Out rose produces raspberry-red colored flowers that have a mild fragrance. Plant a Double Knock Out rose from early spring through early fall.

Step 1

Decide where you want to plant the Double Knock Out rose bush. As with all roses, the Double Knock Out rose bush prefers full sun for optimum growth and flowering. Ideally at least six hours daily.

Step 2

Loosen the soil in the planting site using a rototiller or a shovel to a depth of about 14 to 16 inches. Take out any sticks, rocks or weeds as your turn over the soil.

Step 3

Dig a hole for the Double Knock Out rose that is four times the width of the planting pot. Keep the hole about the same depth as the planting pot or about the same size of the root system if planting a bare-root Double Knock Out rose. If you are planting more than one rose bush, each hole should be between 4 and 6 feet apart.

Step 4

Remove the Double Knock Out rose from its planting pot. Tip the pot upside-down and gently wiggle the planting pot until you can free it from the root system. You can also cut along the entire perimeter of the pot starting at the rim or a drain-hole to remove the pot from the root system.

Step 5

Amend the soil you removed from the hole. Fill up a 5-gallon bucket full of coarse sand or perlite for clay-like heavy soils. Use aged manure or dehydrated compost for soil that is light and sand-like. Work the amendment deep down into the soil.

Step 6

Measure out about 1/4 cup of super-phosphate fertilizer. Spread the super-phosphate onto the soil you removed from the hole and mix it in thoroughly.

Step 7

Place the Double Knock Out rose into the planting hole. For a container grown rose, the root ball should be sitting in the soil the same level it was growing at in the container. If you are planting a bare-root Double Knock Out rose, create a conical mound of soil in the hole that is about 4 to 6 inches high. Spread out the roots of the rose onto the mound of soil.

Step 8

Fill the planting hole about half-full of soil. Pour water into the hole to fill it about two-thirds full. Use your hands to push the soil down around the roots. Fill the remainder of the planting hole full with soil.
