Ditto that in South LA.
I always presumed rust was just the way it is around here, but the 1 and 2 yr potted plants from cuttings in a different part of the yard have yet to rust, but the whole frankenfig is defoliated, with some new growth.
I think that clearing away the fallen leaves may actually pay dividends next year, I've never done that before, despite the general consensus in favor. I just figured the fungus is ubiquitous, what's the point? Plus I'm lazy.
