Plant roses in a sunny area with good air circulation, but out of the wind that can damage the canes. In windy areas, a nearby fence or hedge can act as a windbreak. While many roses will grow in filtered shade, the lack of sunlight will reduce the number of flowers. For best results, roses should get 5 to 6 hours of bright sun a day. The best soil for the rose is one that is moist but well drained.
Plant bare-root roses as soon as possible. If immediate planting is delayed, keep the rose dormant by storing it in a dark, cool area with a damp covering. The bare-root roses shouldn't be stored for over a week.
Soak the roots in water the night before planting. Roots of roses can grow up to 16 inches long, so before planting clear the rocks and cultivate the soil surrounding the area so that the root growth won't be inhibited.
The swollen area above the root is the bud union. In temperate climates, plant the rose so that the bud union is at the soil surface. In colder climates that see winter temperatures below freezing, the bud union should be 2 inches below the soil surface. In areas with colder winter temperatures, the bud union can be as deep as 4 inches.
Fertilize the rose when a growth spurt is noticed, usually about a month after the buds sprout. Fertilizer applied earlier could damage the roots.
Roses purchased at garden centers and nurseries are usually in containers. Miniature roses, usually used as potted plants, can be planted like container roses outdoors.
Roses purchased in containers can be planted to the same depth in the ground as they are in the container. Like bare-root roses, it is important to remove the rocks and loosen the soil so that the roots can spread.
Miniature roses can be grown in containers, but need at least 4 to 5 hours of sun each day. The soil in the container will dry out quicker and the container rose will have to be watered more often than the rose planted in the ground. Keep the container rose at temperatures above 28 degrees F.
Placement of Roses
Roses don't transplant very easily, so it is important that they are given enough room to grow right from the start. Old garden roses and shrub roses should be planted about 4 to 6 feet apart. Climbing roses that will grow along a fence should be spaced at 8 to 10 feet, while miniature roses can be planted in groups at a distance of 8 to 18 inches, depending on their size at maturity.
