Miniature rose bushes come in more than 100 different varieties ranging in height from 8 to 24 inches tall. They have small buds, about dime- to quarter-size, in almost every color except blue. They do well as both a container plant and an outdoor plant, but because they require so much sun they thrive outdoors. In order to produce a healthy plant with numerous blooms, this little plant must be cared for properly.
Choose the best area possible for planting the miniature rose bush. If you wish to keep a potted bush, place it in a southern or western facing window where it will receive at least five to six hours of sunlight a day. Alternatively, plant the bush in a sunny area with well-drained fertile soil, spacing multiple bushes about 12 inches apart.
Water your miniature rose deeply, giving it about 1 to 2 inches of water a week during the growing season. Water container plants whenever the top inch of the soil dries.
Fertilize the miniature roses when they begin to bloom with a rose fertilizer or a slow-release shrub or tree fertilizer. Follow the directions on the package for application instructions. Do not over-fertilize or the miniature rose will have excessive foliage growth and little flower growth. For outdoor plants, stop fertilizing in August to harden off the plants for the winter.
Prune minimally during the growing season, clipping off faded flowers, yellow leaves and dead branches with pruning clippers. This will encourage more blooms and keep the rose bush healthy.
Provide winter protection for the miniature roses. Mound soil around the base of the plant and place a thick layer of leaves in the bush to protect it from frost injury. Do not cover the plant completely as this may smother it.
Remove the winter protection in early spring after the danger of frost passes. Prune more heavily at this time, stripping away the leaves so you can see the branches more easily. Clip out dead, diseased, weak and old canes. Shape the bush however you desire. Compared to other rose bushes, miniatures roses are not picky about how you prune. Also dig out any sucker growth at this time.
