How to Propagate Banana Plants

Banana trees grow fast, provide quick shade and add an exotic tough to the garden. Bananas can reach their full height and maturity in a few weeks. Their long flat leaves unfurl from the center and splay outward creating shade and a taste of the tropics. If you live in a tropical or subtropical climate, growing bananas should pose no difficulty. If you live in a colder climate bananas can be re planted each spring, as they will not survive a cold winter.

Whether you are a cold climate gardener who wants to propagate young trees for the following years planting, or a warm climate gardener that wants to increase the number of bananas in the garden, propagating these fast growing trees is easy to do.

Dig out the suckers that grow around the base of a mature banana plant. Banana plants grow from a rhizome; the rhizome will produce suckers that will shoot up around the base of the plant. To remove the suckers from the rhizome slip a sharp spade between the sucker and the mature plant to cut the sucker free and then dig it out of the ground. Remove suckers when they are between 2 and 6 inches in diameter at the base.

Prepare the pots or garden bed that you wish to use to propagate your new banana plants. The soil should be able to drain well. If you are using planting pots make sure they have holes in the bottoms to allow the water to drain through the pot.

Plant the suckers in the ground or in pots making sure they are planted at the same depth that they were when you dug them out.

If you wish to use your banana plants for ornamental purposes or for shade then they can be planted a foot or two apart. However if you are hoping to harvest fruit off the banana then they should be planted 8 to 10 feet apart.

When the new plants reach full height they will send out new suckers. Remove the suckers and use them to propagate new banana trees.
