fertilizing banyan trees?

[terracore]

I don't know if I'm looking at anything that dramatic. The neighbor has a banyan tree on their property that looks to be up to 100 years old and it's pretty confined. I think the lack of soil and nutrients in OLE is self limiting. There is nice clear area around the tree, maybe 30 feet from the tree itself, then after that it's mostly junk invasives. The ohia lived outside the clear zone without any issues until ROD showed up. The area around the banyan in the clear zone was mostly full of bamboo orchids, it looked sort of like a magical place, then the pigs came in and scraped the area around the tree bare.

I'm not worried about runners, the trees are about 1000' from anything that I care about, and wouldn't reach anything within my lifetime.
