How to Grow Bananas Indoors

Overview

Unless you live in a tropical climate, it's likely that you have never entertained the idea of growing bananas. Yet, with a little skill and a few dwarf banana trees, even Alaskans can enjoy growing their own bananas indoors.

Step 1

Choose a dwarf banana tree. Super Dwarf or Dwarf Cavendish, Dwarf Red, Dwarf Brazilian or Raja Puri are suitable varieties for indoor growing.

Step 2

Purchase high-quality potting soil. It should be porous and well-draining, with a pH between 5.5 and 6.5. For best results, mix 3 parts potting soil with 1 part sand.

Step 3

Repot the banana plant into a larger container. The new pot should be deep enough to completely cover the roots of the tree and allow for adequate water drainage. Do not cover the corm completely; the top 20 percent should be uncovered until the plant has several bigger fronds.

Step 4

Place the pot in a room that receives six to eight hours a day of indirect light; you can also use an artificial grow light. The room should stay above 60 degrees F and be free from drafts.

Step 5

Water the plant thoroughly. Do not worry about overwatering your bananas as long as the pot can drain and they are not standing in water.

Step 6

Fertilize once a week for maximum growth with a water-soluble, 8-10-8 fertilizer.
