Scott, don't get rid of the tree! Give it a chance. Figs are tough! This has never happened to me, so, if it did, I'd smother it with Thuricide, strip it of it's leaves after chopping it in half, and wait.......... Drastic, but sometimes drastic measures produce dramatic results. Not telling you to do that. It's just what I'd do, but... consider the source! :-)
