I'll keep you posted, I stunted the big one by moving it. They are real sensitive.

Balsa trees are "nurse" trees. The seed lay dorment for decades and in the event of a forrest fire (boils the seeds) that clears the land, the trees sprout up and hold the soil in place. The long term trees grow too slow. The balsa trees last less than 10 years, and by then the seeds have been spread, the tree dies and the long term trees take over.
