Miniature roses are tiny versions of the popular shrub rose. They are adaptable, dependable and very easy to grow. According to the University of Illinois Extension Service, miniatures descended from a single dwarf China rose called "Rouletii." Chinese gardeners were the first to propagate miniatures, and the tiny blooms became popular in the United States after World War II. Planting miniature roses in containers is an easy way to bring color into your garden or home.
Choose a location with at least six hours of direct sunlight. The best indoor choice is a south- or west-facing window. Miniature roses need a warm location that averages 70 degrees F in the day, 60 degrees F at night, according to the Iowa State University Extension Service.
Select a pot at least 6 inches deep that has several drainage holes. Use a soil mix that is equal parts of potting soil, peat moss and perlite. Place your rose in the pot, fill with soil to the base of the crown (where the branches start to separate) and tamp down the soil to remove air pockets.
Water well, being careful not to get water on the rose's leaves. Water the plant at least once a week or when the top inch of soil is dried out. It's better to water deeply once a week than to water lightly several times a week. Don't let the pot sit in water because the plant's roots will rot.
Fertilize once a month with a general fertilizer, such as Osmocote or Miracle-Gro, when the roses are blooming. Do not fertilize during the winter when the shrubs are dormant. Too much fertilizer will lead to salt buildup and can inhibit blooming.
Deadhead the blooms when they have faded, cutting the plants back to the uppermost five-leaflet leaf. Remove yellow leaves and dead branches. Spray with a rose fungicide if you notice black spots developing.
