Banana Tree Plant: Indoor Grow and Care Guide

Banana tree plants (Musa spp.) are popular houseplants for their lush foliage and tropical appearance. Banana plants, also known as banana trees, are herbaceous plants lacking woody stems. They feature upright stalks that hold large, vibrant green leaves.

In spring, banana tree plants produce flowers and edible fruits in hues of green and yellow. They rarely bear fruits indoors, but this also depends on the variety. Banana tree plants range in height from 2 to 6 feet, with certain varieties remaining smaller.

Common Indoor Banana Tree Varieties

The most suitable banana trees for growing indoor plants are the dwarf varieties. They thrive indoors under the right conditions and reach 10 feet. These banana varieties include:

Dwarf Cavendish (Musa acuminata)

The Dwarf Cavendish variety grows to a height of 8 to 10 feet. Its leaves reach 6 to 10 inches long, making it suitable for container gardening.

Dwarf Red (Musa acuminata ‘Dwarf Red’)

The Dwarf Red has an attractive red or maroon-colored pseudostem. It reaches a height of approximately 4 to 6 feet and adds a splash of color to your indoor space.

Veranda (Musa acuminata)

The Veranda banana tree reaches a height of 10 feet and spreads 4 to 6 feet wide. It has lush green foliage and originates from South East Asia. Homeowners in suitable climates use it as a landscape.

How to Care for a Banana Tree Plant

Caring for a banana tree plant requires using the right soil composition, fertilizer, temperature, and humidity.

Light Requirements 

Banana trees are tropical plants native to sunny conditions. When growing your banana tree indoors, place it near a sunny window. Indoor banana tree plants require at least 6 hours of bright, indirect sunlight daily.

Consider supplementing poor lighting conditions with grow lights. Place LED or fluorescent bulbs within 12 inches of the banana tree’s top. Be careful not to expose the plant to excess light to avoid scorching the leaves. 

Soil Mix and Composition

The right soil type for banana plants should be moist, well-draining, and rich in organic matter. Maintain an acidic pH level of between 5.5 and 6.5.

A mix of peat moss, perlite, and compost provides good drainage while retaining moisture. Most pro-gardeners recommend a soil ratio of:

  • 60% potting soil
  • 20% organic matter (compost, well-rotted manure, or coconut coir)
  • 10% perlite or vermiculite
  • 10% peat moss.

Avoid heavy or compacted soils since they often lead to waterlogging. 


Choose a pot about 2 inches (5 cm) larger than your banana tree’s current root ball. It should have enough drainage holes at the bottom to allow excess water to pass through. This helps prevent waterlogging, which leads to root rot.

Transplanting and Repotting

Banana trees need repotting once a year to increase their vigor. Increase the pot size by 2 to 3 inches and replace the potting mix with a fresh one.

  1. Remove the plant from its container and loosen the soil around the roots.
  2. Trim down aged and damaged roots.
  3. Transplant the plant in a larger pot and water it.
  4. Allow the excess water to drain before returning it to its original location.

Temperature and Humidity

Banana trees prefer warm temperatures similar to their tropical habitat. Keep the temperature between 75°F to 85°F (24°C to 29°C) during the day and above 60°F (15°C) at night. Avoid exposing the plant to cold drafts or drastic temperature fluctuations.

Indoor environments often lack the high humidity levels that banana trees thrive in. Increase humidity around the plant by misting the leaves with water. Use a humidifier, or place the pot on a tray filled with water and pebbles. Grouping plants also creates a microclimate with higher humidity.


Banana trees are heavy feeders and benefit from regular fertilization. A banana tree plant needs one and a half pounds of nitrogen, phosphorus, and potassium (NPK) 8-10-8 fertilizer once per month.

Dwarf banana tree varieties need that amount in half. If you prefer regular fertilization, use a balanced, water-soluble fertilizer. Follow the product instructions for application rates and frequency.


Banana trees need regular watering to keep the soil evenly moist. Check the top inch (2.5 cm) of soil and water when it feels dry.

Avoid overwatering, as it leads to root rot. Ensure proper drainage using a pot with enough holes to let out excess water.

Pruning and Training

Remove dried, damaged, or yellowing leaves regularly to maintain plant health and appearance. Prune away dead or spent flower stalks after fruiting to redirect the plant’s energy for new growth. Trim any unwanted suckers, which are smaller offshoots from the main stem.

How to Propagate Banana Trees

Banana trees are propagated through a process called suckering or division. Here’s a step-by-step guide to propagating banana trees:

  1. Pick a Healthy Parent Plant: Choose a mature and healthy banana tree as the parent plant for propagation. Ensure the parent plant is free from pests, diseases, and signs of stress.
  2. Identify Suckers: Look for small shoots or suckers growing at the base of the parent plant. Suckers are offshoots that emerge from the rhizome of the banana tree. Select healthy and well-developed suckers for propagation.
  3. Prepare the Suckers: Use a sharp and clean knife or garden shears to separate the selected suckers from the parent plant. Make sure to include a portion of the rhizome with each sucker. Trim the leaves of the suckers to reduce water loss through transpiration.
  4. Prepare Potting Containers: Fill small pots or containers with a well-draining potting mix. The mix should be loose and rich in organic matter. Make sure the pots have drainage holes to prevent waterlogging.
  5. Plant the Suckers: Gently plant each sucker in its pot and bury the rhizome portion in the potting mix. The top of the rhizome should be level with the soil surface. Firmly press the soil around the sucker to provide stability.

Pest and Disease Management

Like other indoor plants, most banana tree plants are prone to various diseases and pest attacks.


  • Aphids: They feed on plant sap and distort new growth. To control aphids, spray affected plant parts with water, insecticidal soap, or neem oil mixture.
  • Spider Mites: Spider mites suck plant juices, which leads to yellowing leaves and webbing. Misting the leaves increases humidity, and spider mites thrive in dry conditions.
  • Mealybugs: They cluster on plant stems and leaf undersides, sucking sap and causing wilting. To eliminate them, use a cotton swab dipped in rubbing alcohol.
  • Fungus Gnats: Fungus gnats lay eggs in the soil, causing their larvae to feed on organic matter and damaging the roots. Allow the soil to dry out between waterings to reduce moisture levels and discourage breeding. Sticky traps also help control adult gnats.


  • Fusarium Wilt: It is a fungal disease that causes yellowing, wilting, and eventual death of the plant. Use disease-free soil and avoid overwatering, as the fungus thrives in moist conditions.
  • Leaf Spot: They manifest as dark spots or lesions on the leaves. Trim affected leaves to prevent the spread of disease. Maintain optimal air circulation and avoid overhead watering to prevent moisture-induced leaf spot development.
  • Root Rot: Excess wet soil conditions due to overwatering and poor drainage lead to root rot. Remove the affected parts if you suspect root rot and repot the plant in fresh, well-draining soil.
  • Anthracnose: It’s a fungal disease that causes dark, sunken lesions on leaves and fruit. Remove and destroy infected plant parts and maintain good air circulation. Fungicidal treatments may be necessary in severe cases.

Troubleshooting Common Issues

Yellowing Leaves and Leaf Browning

The leading causes of yellowing in the banana plant are overwatering, underwatering, and insufficient light. Allow the top inch (2.5 cm) of soil to dry out between waterings and ensure the pot has proper drainage. 

Check the moisture level of the soil, and if it’s dry, water the plant. Also, ensure that your banana tree receives adequate bright, indirect sunlight.

Leaf browning occurs on the tips or edges of the leaves due to dry indoor air. Increase humidity around the plant by misting the leaves with water. Also, avoid placing the plant near drafts or heating vents to prevent drying out the leaves.

Stunted Growth and Wilting

Stunted growth and wilting indicate three underlying issues. First, check if the roots have outgrown the current pot and repot into a larger container.

Overwatering or underwatering also leads to stunted growth and wilting. Assess the moisture level and adjust your watering routine to maintain moist but not waterlogged soil.

Extreme temperature conditions cause stunted growth and wilting in banana trees. Avoid exposing the plant to cold drafts, as they damage the leaves and affect growth. Maintain a warm and consistent temperature.

Nutrient Deficiencies 

Banana trees are heavy feeders. Hence, improper fertilization leads to nutrient deficiencies. Ensure you’re using a balanced, water-soluble fertilizer. An indoor plant-formulated or banana-specific fertilizer is ideal.

Follow the instructions on the fertilizer package for application rates and frequency. Consider supplementing with a potassium-rich fertilizer to promote fruiting.
