The super dwarf banana plant is compact and bears small, sweet bananas. Super dwarf are becoming popular house plants, especially for people who live in colder climates but want a touch of tropical ambiance in their homes. Super dwarfs are also fairly easy to take care of. The main trick to keeping your super dwarf happy and healthy is giving it enough water.
Your super dwarf banana plant requires a large amount of water, so you'll want to make sure that the soil you plant it in can retain enough water yet still drain well. A good soil composition for the dwarf banana would be one part coarse sand or perlite, one part garden soil and two parts peat.
Position your super dwarf in partial shade or indirect sunlight. Unlike other banana plants, the super dwarf does not grow well in full sun, partly because the super dwarf will have difficulty retaining enough water in hot conditions.
Give your super dwarf liquid plant food no more than once per month. The plant will grow healthy and bear fruit if you feed it well.
Plant your super dwarf banana plant outdoors if you live in a climate that has an annual minimum temperature of 20 degrees F or warmer. If you live in a colder climate, you can keep your super dwarf in a pot indoors. A six-, eight- or 10-inch pot should work well.
Inspect your super dwarf for spider mites. Look on the leaves -- especially the undersides -- for these mites, which are the most common insects that are attracted to the super dwarf. To get rid of spider mites, spray the plant with a strong stream of water. For tougher infestations, use a "miticide" or an insecticide that is safe for the banana plant.
