Plantains have been cultivated for thousands of years and their origin seems to be the Malaysian peninsula, New Guinea, and Southeast Asia. These trees can reach a height of 7 to 30 feet, depending on many factors such as variety, amount of sun, soil, and overall climate. In fact, plantains are a hybrid of two species of banana: Musa acuminata and Musa balbisiana. Unlike bananas though, plantains are never eaten raw, but always cooked the same way you would cook a potato.
Plantain trees are grown from long, 12-15 foot underground rhizomes. If you choose to grow plantains from rhizomes (same idea as growing from seeds), you’ll need to dig a very large hole. We recommend purchasing a small plantain tree to ensure good, healthy growth and avoid any future growing problems.
This in turn yield some very large and impressive leaves (about 9 feet in length and 2 feet across).
Plant the tree in well draining soil and in full sun.
Protect the newly growing plant from high winds and make sure to leave 4-6 feet of space in between the tree and other plants.
Dig a hole that’s as deep as the root ball.
Add about 4-6 inches of organic mulch around the tree. Spread the mulch all around the tree to keep the soil moist.
Caring for plantain trees:

Plantain trees thrive in moist (not soggy) soil, so be sure to always check the soil and water regularly. Do not let soil dry out!
If there are cold fronts, be sure to protect the tree by covering it with a blanket, adding heaters or lights, or bringing it indoors if in a pot.
Plantain trees are very susceptible to the cold, so protecting them from dropping temperatures is crucial.
The rhizome can actually survive temperatures as low as 22 F (-5C), but the rest of the plant will die.
Fertilize your plantain tree once a month during the summer with a slow release fertilizer of 8-10-8.
Plantains are actually heavy feeders and a mature tree will need about 1-2 pounds. Do this by spreading out the fertilizer in a 4-8 foot radius around the plant and then lightly working it into the soil.
Use gardening pruners to remove suckers. This will ensure that all the energy gets diverted to the main plant.
If you are propagating a new plant, leave only one sucker onto the plant and let it grow on the parent plant for 6-8 months before removing it completely.
Plantains are usually ready for harvest anywhere from 14 to 20 months depending on the climate and other factors.
Flowering usually happens within 10-15 months, while an additional 4-8 months is needed for fruit it develop and ripen.
To harvest, simply cut off the entire bunch from the top of the stalk. Use a sharp blade to do this, such as a machete.
