Unfortunately, I'm one of those guys who does not grow this plant... because of my latitude. But I can see why a leaf that falls off the tree in the fall would dry darker than one that is plucked in full growth... The tree sucks out as much of the nutrients as it can, from the leaf, before it lets it fall. I don't know if the leaves turn yellow or some other colour before they fall off, or whether they just drop them green... which some tropical species of mine have done, when exposed to our fall in Canada (my area, anyway, where day lengths in winter can be as little as seven and half hours, and in summer as much as 19 hours).organics wrote: I can't think of a good reason that a leaf that hits the ground for a minute dries infinitely darker than a leaf right beside it on the tree that is plucked and dried without ever hitting the ground... odd thing for sure. I just know it's not normal, so I don't risk it... )
The natural range for Kratom... is that pretty much equatorial? I'm not looking at a map, but I know Southern Asia is pretty close to the equator... Do they drop their leaves, in their natural range?
But either way, if it's dropping leaves, unless they froze, the plant would have stripped what it could. The chemistry would change. To unknown effect. Not something I'd rush into (especially without a history of indigenous use of dropped leaves, which of course there wouldn't be any, if in it's natural habitat, it doesn't drop leaves).
Not the latest from google, anyway... but still without any real experience with raising Kratom. It just makes sense to me. I know my Voacanga freaks me out every year; I swear I'm going to lose it... then it regrows, vigorously. Which it starts in the fall, rather than spring, so go figure that.
Could that be any part of the leaf-dropping thing?
