How to Grow a Banana Tree Inside & Care Guide

Indoor banana tree? Yes, you’re quite correct.

Banana plants can be grown successfully indoors if you do not have access to a warm climate suitable for outdoor cultivation.

A banana tree makes a great houseplant if given adequate light and water.

The foliage of a banana plant is visually appealing, and the white flowers that emerge from purple buds are a pleasant bonus.

Keep in mind that the Musa basjoo banana tree does not yield edible fruit, unlike some other banana tree kinds.

Therefore, you should research the indoor banana tree kind you have or are considering to make sure it is suitable for your space and environment.

Please find below some advice on how to properly care for a banana tree in the house.

How to Grow Banana Inside

Unless you want a pretty huge houseplant, you should probably choose a dwarf kind of banana tree if you want to keep one inside.

You’ll still need a big pot with plenty of depth for its extensive roots. In addition, it needs to drain properly.

Indoor banana plants, like their outdoor counterparts, require lots of sunlight and soil that is both nutrient-rich and well-drained.

True, most species of indoor banana trees need at least 12 hours of continuous bright light per day.

While growing bananas, make sure the plant doesn’t become too hot or it could get scorched. Soil pH between 5.5 and 7.0 is ideal for growing bananas.

Make sure the rhizome of the banana is planted upright and that the soil completely covers the roots.

Taking Care of a Banana Tree Inside

Indoor banana plants need regular feedings, especially when they’re actively growing in the spring and summer.

For this reason, you should provide them with a balanced soluble fertilizer once every month. Spread this all over the inside of the bottle.

Additionally, these plants flourish in warm, damp climates.

Bananas grown inside require warm temperatures, ideally in the 80s during the day and 67 degrees Fahrenheit (19 C) at night.

It’s true that an indoor banana tree requires more water than its outdoor counterpart, but the plant should never be left in a tray of water.

There should be some time between waterings for the plant to dry out.

It is possible to keep their foliage hydrated and cheerful by misting it.

Also, dust can be removed from an indoor banana plant by wiping its leaves with a damp rag or sponge on a regular basis.

In milder climates, indoor banana plants can spend the summer months outside. On the other hand, they have to be shielded from the cold and wind.

It’s important to acclimatize plants both before putting them outside in warm weather and again when the temperature drops.

Utilize movable platforms with wheels to relocate vegetation with ease.

Caring for a banana tree in the house is as simple as that.

If you grow bananas inside, it’s like bringing a piece of the tropics into your living room.


Remove any secondary stems from the banana plant before it bears fruit.

Leave one sucker after six to eight months of growth. In the following growing season, this plant will take the place of the main stem.

Remove the fruit, then prune the main stem to a length of 2.5 feet.

After a few weeks, cut off the remaining stem, but do not remove the replacement sucker.

Propagating Banana Trees

Divvying up is the most efficient means of spreading.

Using a sharp spade, cut the rhizome (horizontal subterranean stem) from the suckers on your banana plant.

Wait until the suckers are at least 3 feet tall and have established their own roots before doing this.

Allow the cut surface of the rhizome piece to dry for a day or more after removing a sucker from the parent plant. The plant can then be relocated to a new place.

Potting and Repotting Banana Trees

Growing banana trees in pots is possible, but they require at least a 15-gallon pot for the best development.

Use a porous, organic potting mix and a pot with drainage holes.

If you put your banana tree in a container, you may bring it indoors out of the cold and wet weather.

However, unlike their ground-based counterparts, banana trees in containers require more frequent and intensive attention in the form of watering and fertilizing.

They may never mature to full size, and their fruit may never materialize.

Even yet, many people favor them because of the greenery.

Banana trees grown in containers need to be divided every three years to remove suckers and repot the resulting plants.

Common Pests & Plant Diseases

Banana tree owners must constantly be on the lookout for the numerous pests and illnesses that can harm their plants. Among the many pests are:

  • Aphids: The bugs cause the leaves to curl and shrivel, and they may also spread diseases that ruin the crop.
  • Black weevils: Jelly-like liquid dripping from the plant is a telltale sign of black weevil infestation, which can be treated with pesticides.
  • Nematodes: This is the most prevalent disease that causes rot in banana trees and bananas.
  • Sap-sucking insects: Banana trees can suffer from mealybugs and red spider mites, too.
  • Scarring beetle: This insect invades in groups and feeds on the plant’s fruit; it is easily controlled using pesticides.
  • Thrips: The fruit of the plant will become discolored and the peel will crack due to this bug.

Banana trees in commercial orchards are protected against the many diseases that plague them by using a variety of fungicides and pesticides available on the market.

Root rot, leaf-spot disease, wilt, and powdery mildew are all things to watch out for with potted banana trees kept inside.
