Find a location in soil that is well draining and gets at least eight hours of sunlight. Keep the rosebushes away from buildings to increase wind circulation.
Spread a 2- to 4-inch layer of compost on top of the planting area, as well as 3 lbs. of super phosphate per 100 square feet of planting area. Till the compost and super phosphate into the soil.
Dig a hole that is 15 inches deep and 18 inches wide. Place a small mound of dirt in the center of the hole. Set the plant into the hole and spread the roots around the dirt mound to protect it. Fill in the hole with dirt so that the grafting point or the portion of the plant where the limbs come out of the hole is set just above the soil.
Buttress the canes of the plant by mounding 4 to 6 inches of soil against them to prevent them from withering while the roots are taking hold. Water the hole and add more dirt if necessary.
