Miniature rose plants can reach between 5 and 36 inches in height, making them an appropriate selection for indoor growth. The plants come in a variety of colours, though they do not all produce the signature rose fragrance. Miniature roses grown indoors may require more maintenance than other houseplants because of their sunlight requirements. They are also susceptible to insects when grown indoors.
Set the potted mini rose in the sunniest window available. The plant requires at least four hours of direct sunlight per day. If none of your windows provide this much sun, install a grow light directly above the rose plant to supplement the lacking hours of light.
Water the miniature roses every day until the water comes out of the drainage holes in the bottom of the pot.
Fill a pot tray with pebbles so the rock level is even with the top of the tray. Set the mini rose pot on the tray. When you water the plant, leave the runoff in the tray to provide extra humidity for the plant.
Mist the top and bottom of the foliage on the rose plants with a spray bottle of water once a week. The rinsing will prevent pest infestations. Wipe down the leaves with a clean cloth after misting.
Apply a slow-release liquid general fertiliser to the soil once a month according to the package directions.
Deadhead the plant as it blooms by pinching off flowers as they fade.
