4. Make a cone in the center of the hole, patting soil firmly into shape (but don't compact). Spread out the roots of the rose over this cone. The placement of the bud union either above or below the soil line is important. If you live in areas with extremely cold winters, bury it about 1 to 2 inches below the surface of the ground for protection. But in milder parts of the country, you can actually plant the rose with the bud union about 1 to 1 1/2 inches above ground level. Begin back-filling the hole with additional soil mixture, gently tamping the soil around roots; water the rose well to help settle the soil. Give the plant a little extra boost with a solution of fish emulsion, following the directions on the bottle.
