Answers to Your Questions: Where Can I Find a Hardy Banana Tree on Canada?

Question

Where can I buy a hardy banana tree? I’m told that this tree doesn’t stand up to our winters. Is this true?

Answer

I’ve seen hardy banana trees for sale in garden centers in the Quebec City area.

The banana tree in question is Musa Basjoo (there are other hardy banana trees, but this is the most common). It’s called hardy because it survives frost and even snow in the mountains of its native northern India. However, there’s a difference between a climate where there’s sometimes frost and one where the ground freezes solid. In fact, its hardiness zone is 7. What’s more, the stores that sell this plant do not guarantee that it will survive the winter: it is offered “at your own risk”. Musa Basjoo is said to survive temperatures as low as -10°C (14?).

Growing in Canada

That said, yes, we’ve seen this plant survive winter in Canada… and without too much difficulty, either. The secret is quite simple: plant it deeper than normal, with its roots about 45 cm from the soil surface, and give it a very thick mulch in autumn. With a mulch of shredded leaves (I suggest them, as they give off heat whereas most other mulches don’t) 35 to 45 cm thick. Under such conditions, the soil will not freeze at all, or only on the surface, so there’s a good chance the plant will survive the winter.

It should be pointed out that in our climate, this plant is grown mainly for its foliage: it rarely flowers or produces fruit, which is not considered edible anyway… but let’s just say that it’s a bit of a shock to say that banana trees are grown in the open ground in our climate!

Produce Fruit Indoors

Indoors, some banana plants have been known to produce fruit, but this requires careful attention to several aspects and I wouldn’t count on it! Choose a dwarf variety to better manage space and make sure the plant receives sufficient light, ideally near a south-facing window or under grow lights for at least 12 hours a day. Maintain warm temperatures between 20-30°C (68-86°F) and high humidity, using a humidifier. Water regularly to keep the soil moist without saturating it, and fertilize monthly with a potassium-rich fertilizer. Re-pot every two to three years and, in the absence of pollinating insects, you’ll need to hand-pollinate the flowers.

  1. Even here on the West Coast of California, banana fruit is rare and of inferior quality. Technically, fruit develops. It just does not develop well without sustained warmth throughout the day and into the night. (The weather does not get too hot here, and even if it does, it gets comfortably cool overnight.) Also, because bananas are tropical, even those that are resilient to frost (because they are from high elevations) are not accustomed to the seasons of Canada. They bloom randomly. If they bloom early in spring, their fruit may have time to develop before frost. However, they are just as likely to try to bloom in autumn. They do not seem to know when to bloom. I grow them regardless, just because they are so compelling.
