From the Conard-Pyle Website, The People who bring you the Knock Out Rose come step by step instructions on how to plant the Bareroot Knock Out Rose.
How to Plant a Bareroot Knock Out Rose:
Step 1. Soak
Soak your bareroot rose in water for 1 to 6 hours. A bucket works well for just a couple roses, while a large garbage can will work if planting several roses.
Step 2. Dig the hole
Dig a hole that is twice as wide and deep as the roots. Incorporate organic material such as manure, shredded leaves or peat moss (potting soil can also be used) into the existing soil making sure that the hole is still deep enough. Backfill the hole slightly to form a mound in the center of the hole.
Step 3. Planting
Position the rose roots over the mound making sure that it stays straight up. You may have to hold the rose in place and backfill more to make sure the bud union (the knobby part of the stem base) is at the correct level. In zones 6-10, the bud union should be about 1″ above the soil surface. In zones 5 and under, it’s a good idea to bury the bud union 1″ or so under the soil surface.
Step 4. Back fill
Back fill hole with soil, firming into place, adding more soil as needed.
Step 5. Watering and Mulching
Water thoroughly around base of plant allowing it to soak in. Repeat step 4 if necessary.
Step 6. Mound and Protect
Bareroot roses are dormant when shipped and they must be protected from drying out until the roots become established. It is important to cover at least 1/3 of the exposed canes with mulch or soil.
Step 7. Watering
For the next couple weeks, check in and water plant as needed to ensure it stays healthy.
Step 7. Check In
In a few weeks, shoots will begin to emerge through the mounding material. It is then safe to remove the mounded material by carefully pulling it away from the base of the bush or by washing it away with a hose. Water your newly planted rose bushes often to ensure that they get a good start. When the rose blooms in about seven to eight weeks, it will be time for good fertilization.
