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??
natalensis roots seem to attach securely on their own with very little assistance...what is important (i think) is to have long roots that are buried right from the start.Great progress! Did you use anything to attach the ficus roots to the host trees? My F. microcarpa is very slow to form roots over the stump. I will try some grafts or fusions with cuttings next year.
