How to Grow Bananas in a Plastic Bag

Overview

Bananas are tropical plants requiring high temperatures and humid conditions for their fruit (bananas) to grow and ripen. It is possible for virtually any home gardener to start a banana plant growing at home, with little more than a plastic bag. It helps if the home gardener has access to an existing banana plant, but if not a banana start, called a "corm" can be ordered online.

Step 1

Obtain a banana tree corm, also known as a bullhead. This is a portion of the tree's root that will sprout a new tree. Corms look like large bulbs growing on the roots of the banana tree. Use a sharp knife to cut off a corm from the root of an existing tree or order a corm online.

Step 2

Cut off the bottom half of the corm horizontally, using a sharp knife. There should be one or more "eyes" on the top side of the corm, similar to those on a potato.

Step 3

Place the corm in a pot of hot water (125 degrees F; use a thermometer to check the temperature) for 20 minutes.

Step 4

Remove the corm from the water and place it in a plastic bag. Seal the bag and place the bag in a warm location, preferably 75 to 85 degrees F.

Step 5

Check the bag every couple of days. Watch for roots to form on the corm. When the roots are 1 inch long remove the corm from the plastic bag and plant it (roots down) in a growing pot filled with potting soil. Plant it approximately 1/2 inch deep. Keep the soil damp at all times and keep the pot in a sunny room. Bananas sprout fastest when the temperature is kept between 75 and 85 degrees F.
