Banana plant lifespan
 

Hello!

I know that after a banana plant fruits, the main stem dies out (I was told this happens after 30ish leaves, yes?). The basjoos, darjeelings, and so on have to be cut back each fall, so does the leaf count reset to zero in spring? Or does it continue from where it left off, eventually shooting up a flag leaf?
I ask because I'm curious to know how long the main plant (not the grove) will live for if it'll never flower or fruit. I've given some away and I don't want the new owners to keep giving away all the pups expecting the mother plant to live forever.

This strongly depends on climate and other inputs.

In Puerto Rico there is no horticultural reason to do this -- so what is the purpose?

No.

Yes.

Good question, i have Basjoo's over 5 years old but no idea how many leaves they have put out in that time.

Thanks for the info, I do see however that Juni,although Puerta Rican lives in NY.
My question on the topic is if a Cuban red takes two years to produce harvestable fruit is it still producing 30 leaves. Also are you saying some plants may produce 25 and others 35 leaves depending on climate and nutrition etc.

According to Gabe, the count of banana leaves is not a good indicator of maturity.

Okay thanks.

Leaf count can only be used if you are tracking a single variety, in a single environment over multiple generations. Basically it equates to how many leaves are produced in a certain amount of time, and the time it takes from planting or from sucker to emergence to flowering is easily predictable if you have consistent growth. Counting leaves at best ends up being a different (but harder) way to measure time (calendars and dates are much easier to work with), and at worst is just confusing because it gives the impression (such as above) that a plant is obligated to flower after so many leaves.

The exact mechanism for banana flowering initiation is not known, but it does not have any direct connection to the number of leaves produced.

Hehe. No... I'm Puerto Rican, but I'm living in western New York state (zone 6) where the plants get cut down for the cold winter. I wouldn't waste my time with basjoos if I were in Puerto Rico. I'd have something exotic & super expensive. Mmmm. *droolz*

I had been told the leaf count varied by species. So I dunno. I see it's not an accurate indicator of bloom time, but I am still curious how long these plants will eventually live to be. An ugly tree can live to be hundreds of years old, but a beautiful banana plant can't? That's not fair.

It is an herb, not a perennial. :)

Hardwoods vary in their active growth cycle, which generally equals the amount of time they die. For instance, a live oak can take 30 years (or maybe it's 70, I can't remember exactly right now) to grow, can live for 1000 years and then it takes 30 (or 70) years for it to die.

If one has a banana plant and it's rather tall and then it breaks or you cut it in half of course it's going to bloom sooner - the amount of leaves means nothing when it's time to bloom. Because sometimes they don't put out any leaves, they'll just bloom - as I've seen happen to one that broke last year. I cut it below where it broke and a week later out came the flag and the bloom - with no fronds on it.

The fruit was worthless but it still did it's thing without making more leaves. And it would have bloomed in late August or September based on others at that time that did. So had it not broke it would have made more leaves but not many.
