This makes sense. If the fig kills the host tree, it will eventually decay and collapse. If that happens the fig loses its ladder into the forest canopy unless its roots have become strong enough to fully support it.an interesting comment was made on our local tree forum the other day, that figs are really just interested in getting their roots into the ground and not that concerned with killing the host tree... I am starting to think more along those lines... they all seem to be doing great living together??
