I used a 25gal fabric pot for my banana plant, but I really don't care for it much because of how hard it is to move the plant around now. I actually just bought a regular 25gal pot to place it into bc every time I try to move it the rootball seems to get stressed due to the lack of support. It does dry out very quickly and I can't bottom water it sooo "Hello Fungus gnats!" as soon as it came in for the winter.. That shouldn't be a problem for your fig tree though since it will be outside or in a garage for winter..Maybe it was just the brand I bought, or maybe I just have bad luck lol, bc it seems other people like them and they are usually pretty reasonably priced.
