How To Grow Banana Trees In Pots (Indoor & Outdoor)
A guide to growing banana trees in pots both for fruit as well as for decoration. Banana trees are a fantastic addition to any home or garden, offering lush tropical foliage and delicious fruit.
Growing Banana Trees In Pots
While these plants are typically associated with large outdoor spaces, they can also thrive in containers, making them an excellent choice for those with limited space or non-tropical climates.
Growing banana trees in pots allows gardeners to control soil conditions, move the plants as needed, and even grow them indoors.
In this post, I will provide an in-depth step-by-step approach to successfully growing banana trees in pots, whether inside your home or in an outdoor garden.
Choosing the Right Banana Variety
Not all banana varieties are suitable for container gardening. Choosing a dwarf or compact variety ensures better success when growing banana trees in pots.
Some of the best varieties include:
Dwarf Cavendish: One of the most popular banana varieties for container gardening.
It grows to about 6-8 feet tall, making it manageable for both indoor and outdoor settings. It produces medium-sized bananas with a sweet flavor and is relatively easy to care for.
Dwarf Orinoco: This variety is more tolerant of colder temperatures compared to other bananas.
It can reach 4-6 feet in height and produces thick-skinned, sweet bananas that are good for both eating fresh and cooking.
Super Dwarf: A true miniature variety that reaches only 2-4 feet in height. This variety is ideal for indoor growing and small spaces while still producing edible bananas.
Musa Basjoo: Primarily grown for ornamental purposes, this banana variety can withstand colder climates. Although it does not produce edible fruit, it adds an attractive, tropical touch to any space.
Selecting the right variety depends on whether you want a decorative plant or one that yields edible bananas.
Additionally, some banana trees require a longer time to produce fruit, so consider your climate and growing conditions when making your choice.
Selecting the Right Pot
Banana trees have extensive root systems, so choosing the right pot and soil is essential for their growth and health.
Start with a pot that is at least 15-20 gallons in capacity (18-24 inches in diameter) to provide ample space for root expansion. A larger pot will prevent the plant from becoming root-bound too quickly.
Ensure the pot has multiple drainage holes to prevent water from accumulating at the bottom, which can cause root rot.
Opt for plastic, ceramic, or clay pots. Plastic pots retain moisture better, while clay pots allow for better aeration. If using a heavy ceramic pot, consider placing it on a wheeled plant stand for easy movement.
Soil Requirements
Banana trees thrive in loamy, well-draining soil. A good mixture consists of potting soil, compost, perlite, and sand for proper aeration.
Aim for a slightly acidic pH level between 5.5 and 7.0. Adding organic materials like aged manure, peat moss, coconut coir, or worm castings improves soil fertility and moisture retention.
Planting the Banana Tree
Once you have the right pot and soil, it’s time to plant your banana tree.
Steps to Planting
Prepare the pot: Fill it with soil, leaving about 3-4 inches of space from the top to prevent soil from spilling during watering.
Position the banana plant: Place the plant in the center of the pot, ensuring the roots are spread out evenly.
Backfill with soil: Gently add more soil around the roots, pressing lightly to eliminate air pockets.
Water thoroughly: This helps the soil settle around the roots. Be sure the water drains properly from the bottom.
Placement: If growing indoors, place the pot near a south-facing window or in a spot with bright indirect sunlight.
Indoor Care for Banana Trees
Growing banana trees indoors requires proper lighting, humidity, and temperature control.
Light Requirements
Banana trees need 6-8 hours of bright, indirect sunlight daily. If natural sunlight is insufficient, use full-spectrum grow lights positioned 12-24 inches above the plant.
Rotate the plant periodically to ensure even growth and prevent it from leaning toward one side.
Temperature and Humidity
Maintain indoor temperatures above 60°F (15°C), with an ideal range between 75-85°F (24-29°C). Humidity should be kept above 50%. If indoor air is dry, use a humidifier or mist the plant daily.
Avoid placing the plant near heating vents or air conditioners, as sudden temperature fluctuations can stress it.
Watering and Maintenance
- Keep the soil moist but not soggy; water when the top inch feels dry.
- Wipe leaves with a damp cloth to remove dust and improve photosynthesis.
- Watch for pests like spider mites and treat them with neem oil or insecticidal soap if necessary.
Outdoor Care for Banana Trees
If growing banana trees outdoors, consider your climate and environmental conditions.
Best Climate and Placement
Banana trees thrive in USDA zones 8-11 and need a warm, sunny location with at least 8 hours of direct sunlight daily.
Choose a wind-protected area to prevent leaves from tearing.
Seasonal Care
Summer: Increase watering frequency and apply a 2-3 inch layer of mulch around the base to retain moisture.
Winter: Move potted trees indoors if temperatures drop below 50°F (10°C). If left outside, wrap the pot in burlap and add a thick layer of mulch around the base.
Fertilizing and Watering Needs
- Banana trees are heavy feeders and require consistent watering and fertilization.
- Apply a balanced fertilizer (10-10-10 or 20-20-20) every two weeks during active growth.
- For fruiting varieties, use a potassium-rich fertilizer to promote healthy banana production.
- Apply compost tea or organic fertilizers every month to enhance soil nutrients.
Watering Schedule
Water deeply 2-3 times a week, ensuring the soil remains moist but not waterlogged. Reduce watering in winter to prevent root rot.
Signs That a Banana Is Ready for Harvest
Color Change: The bananas will change from green to yellowish-green or fully yellow, depending on the variety. Some varieties may even develop brown spots as they ripen.
Fruit Size and Shape: The bananas should appear full and plump, with a rounded shape rather than angular edges. Immature bananas are more rigid with sharp ridges.
Texture and Firmness: When gently squeezed, ripe bananas will have a slight give but still feel firm. Overripe bananas will be too soft.
Time Since Flowering: Bananas typically take 75-100 days after flowering to reach maturity. If your tree has flowered and it’s been around this time frame, check the fruit closely.
Easy Separation: A ripe banana will separate easily from the bunch when twisted gently. If you need to use excessive force, it may need more time.
Stem Drying: The stem of the banana bunch may begin to dry or turn brown, indicating that the fruit is reaching full maturity.
Flower Petal Shedding: The dried remnants of the flower at the banana tips will naturally fall off when the fruit is ready.
Harvesting Banana Fruits
- When harvesting Cut the entire bunch using a sharp knife.
- Allow bananas to ripen indoors at room temperature.
- After harvesting, prune the main stem to encourage new growth from suckers.
