Light
Snow banana trees appreciate plenty of sunlight. If this is lacking, the color of the large leaves can be impacted. During the warmer summer months, they’ll do well outside, as this will maximize the amount of natural light they receive.
Soil
Your snow banana tree will need a well-drained soil or potting mix. Overly wet conditions aren’t good for this plant, but they do like to be kept moist.
Water
Snow banana trees appreciate regular watering. They benefit from consistently moist but not waterlogged soil. Take care not to let them dry out for prolonged periods before rewatering.
Temperature and Humidity
Snow banana trees might be hardier than some other Ensete species, but they still prefer frost-free, dry, and sheltered conditions during the winter. They do best in warm, humid, tropical-type climates.
Fertilizer
These trees are heavy feeders. Snow bananas grow fast, and it takes a lot of energy to keep their large trunk, leaves, and flowers healthy. Regular fertilization during the spring and summer will help ensure they put on their best display.
Pruning
Pruning a snow banana tree should include removing the dead, browned, diseased, or pest-ridden leaves. Selectively prune branches if desired for a certain shape. There is no best season for pruning this tree, as it isn’t anticipated that you’ll do any heavy cutting - you’ll simply remove what is already dead or dying.
Propagating Snow Banana Trees
Ensete species like the snow banana tree are known for being much more difficult to propagate than their banana (Musa) relatives. Trying to do it from cuttings or division can be exceptionally tricky.
How to Grow Snow Banana Trees From Seed
Snow banana trees are best grown from seeds. The seeds should be soaked in warm water for around 48 hours. If you don’t have a propagator, you can place them on top of a warm radiator, or just make sure you regularly change or top up the water. Sown seeds benefit from being sealed inside a bag or placed in a consistently damp paper towel to keep the humidity high. They appreciate daytime temperatures above 77 degrees Fahrenheit. Positioning them on a well-lit windowsill can be a good idea. The seeds can take at least three months to germinate and should be well-spaced.
Overwintering
There have been reports of this species surviving the winter months outside in zone 7b, providing they have appropriate protection. To ensure success, heavy mulching and wrapping of the plant leaves and body would be required. If you’re expecting frost, bring your Snow Banana Tree into an appropriate indoor space to ensure a better chance of survival.
Common Pests and Plant Diseases
Several common garden pests love snow banana trees. These include mealy bugs, red spider mites, and aphids. Insecticidal soaps and horticultural oil can help. Diseases common to the tree include leaf spot or leaf streak, which can both be treated through the use of fungicides.
