Banana Plant Indoor Growing Guide: Complete Plant Care
Ever thought about growing a banana plant indoors? We’re all familiar with bananas, especially the Cavendish type you find at the grocery store, but there are plenty of other varieties out there. If you’ve visited a tropical area, you might have spotted these stunning equatorial plants and been amazed by their towering height—some reach 20-40 feet (6-12 m).
Obviously, a plant that big isn’t ideal for indoor growing. But don’t worry—you can grow a gorgeous banana plant inside! Some varieties, usually dwarf types, are much better suited as indoor banana trees. Keep reading to learn how.
Can You Grow a Banana Tree Indoors?
Yes! You can grow a banana plant indoors, but stick with a dwarf variety that stays under 10 feet (3 m).
Banana Plant Indoor Care
Don’t get your hopes up too high for fruit—indoor banana plants rarely produce any, and if they do, it can take 3-4 years. If their needs aren’t met or the variety is just ornamental, you won’t get bananas.
Like all plants, banana trees have specific needs for light, water, temperature, humidity, and soil. If you can match these conditions at home, you’ll be able to grow a striking, elegant banana plant indoors.
- Light – Banana plants love light—lots of it. In their natural habitat, they often get 12+ hours of sunlight, which is tough to replicate indoors. To help your banana tree thrive, consider using grow lights.
- Water – These plants are thirsty and can’t handle drought. Keep the soil consistently moist. If the leaves droop, it’s a sign they need water. That said, banana plants hate soggy roots, so don’t let them sit in a water-filled saucer.
- Temperature & Humidity – Another challenge? Most banana plants prefer it hot and humid—around 80-89°F (27-32°C) during the day and no cooler than 69°F (20°C) at night. They also love humidity. A humidifier nearby helps, as does grouping them with other tropical plants. Daily misting boosts moisture too.
- Soil – While bananas need plenty of water, they’re prone to root rot, so well-draining soil is a must. Pick a high-quality potting mix with perlite for drainage and plenty of organic matter.
- Fertilizer – Banana plants are heavy feeders. During their growing season (spring to fall), fertilize weekly with a balanced liquid fertilizer—but dilute it to half strength to avoid overfeeding.
Problems, Pests & Diseases
Wet roots can cause fungal issues. Other concerns include anthracnose, wilt, and mosaic virus. Over-fertilizing can burn leaf tips. Outdoor banana plants face pests like banana weevils, borers, root nematodes, and grasshoppers. Indoors, watch for red spider mites, aphids, scale, and mealybugs.
Pruning an Indoor Banana Plant
To keep your plant looking its best, prune damaged leaves when needed. Banana leaves can yellow, brown, get holes, or show pest/disease marks. Use sterile shears or a knife to cut the stalk about an inch from the trunk. Also, remove any suckers (new shoots) growing from the rhizomes.
Propagation
Your indoor banana plant will likely produce “pups”—shoots growing from the rhizomes near the main stem. These can be separated for propagation:
- Dig up the rhizome and carefully cut the pup away with a sharp knife.
- Make sure the pup has its own roots.
- Let the rhizome dry for 48 hours before replanting.

Repotting
Repot your banana tree every year into a container 2-3 inches larger than the current one.
Best Indoor Banana Plant Varieties
Dwarf types work best indoors. Try Dwarf Cavendish, Dwarf Red, or Veranda.
FAQs:
1. Can I grow a banana tree indoors?
Yes, you can grow a banana tree indoors, but you should stick to dwarf varieties such as Dwarf Cavendish, Dwarf Red, or Veranda. These varieties are better suited to indoor conditions, as they grow to a more manageable size (under 10 feet).
2. Do banana plants need a lot of sunlight?
Yes, banana plants love sunlight. They require at least 12 hours of light per day to thrive. Since it’s hard to replicate natural sunlight indoors, using grow lights is recommended to provide the necessary light.
3. How often should I water my indoor banana plant?
Banana plants are thirsty and need consistently moist soil. However, they don’t like soggy roots, so it’s important to ensure proper drainage. Water the plant when the soil feels dry to the touch, but avoid letting the plant sit in standing water.
4. What is the ideal temperature and humidity for growing a banana plant indoors?
Banana plants thrive in warm temperatures, ideally between 80-89°F (27-32°C) during the day and no cooler than 69°F (20°C) at night. They also require high humidity, so consider using a humidifier or misting the leaves daily to maintain moisture.
5. How do I prevent diseases and pests on my indoor banana plant?
Over-watering can cause root rot and fungal issues. Common pests include red spider mites, aphids, and mealybugs. Regularly inspect your plant and treat it with insecticidal soap or neem oil if necessary. Keep the soil well-drained and avoid over-fertilizing to prevent leaf tip burn.
6. How do I prune my indoor banana plant?
Prune your banana plant by removing yellow, brown, or damaged leaves. Use sterile shears to cut leaves an inch from the trunk. You can also remove any suckers (new shoots) growing from the rhizomes to maintain a neat appearance.
7. Can I propagate my indoor banana plant?
Yes, banana plants produce “pups,” or shoots, that can be propagated. To do this, carefully cut the pup away from the rhizome, ensuring it has its own roots. Let the rhizome dry for 48 hours before replanting it.
8. How often should I repot my indoor banana plant?
Repot your banana plant every year, transferring it to a container that is 2-3 inches larger than the current one. This helps to accommodate the plant’s growing root system.
9. Will my indoor banana plant produce fruit?
Indoor banana plants can take 3-4 years to flower, which signals that fruit may be on the way. However, indoor plants often require very specific conditions—especially light—and even then, they may not fruit. Some varieties are grown only for ornamental purposes.
Conclusion:
Growing a banana plant indoors can be a rewarding and tropical addition to your home. While it requires specific care—especially in terms of light, water, temperature, and humidity—it is very much possible with the right conditions. Dwarf varieties like Dwarf Cavendish and Dwarf Red are the best choices for indoor environments. Regular care, pruning, and proper watering can help you maintain a healthy and vibrant plant. Though fruiting may take several years, your banana plant will still provide a beautiful and unique aesthetic to your space.
Enjoy growing your indoor banana plant and watch it thrive with patience and attention! 🌿🍌
