Miniature potted roses accent a home's interior with beautiful rose blooms. Caring for mini roses indoors is similar to caring for full-size roses outdoors, only with less work. Indoors, the plant will typically be less prone to pests, and you won't have to worry about weather damage. Less care doesn't mean no care, of course. Keeping certain things in mind will help you maintain your mini roses.
Keep your indoor mini roses in a sunny area of your home. The roses will not bloom unless they get enough sunshine.

Check the rose's soil for dryness each day. If you stick your finger in the pot and the soil is dry an inch down, you need to water. Water your mini roses deeply so the roots get a good drink--continue until the water starts seeping out of the drainage holes in the bottom of the planter.
Cut off old blooms with a sharp knife or pruning shears. Guide to Houseplants.com advises cutting the stem below the bloom at a 45-degree angle. This is a good time to check for insects on the roses. Deal with insects quickly by squishing them or spraying them with pesticide. Most houseplant pesticides will work fine for insects on mini rose plants.
Fertilize mini indoor roses with the same fertilizer you use on outdoor roses. Many brands offer fertilizer geared towards roses. Only fertilize the roses when they're in their growing season (spring and summer). You shouldn't have to fertilize indoor potted roses as often as outdoor roses.
Prune off dead stems and foliage, cutting the stems at a 45-degree angle. Grow-Roses.com suggests pruning the mini roses back, leaving only 3 inches in height, when the roses are dormant in winter.
