I’m pretty new to fig trees too and I’m trialing both plastic and fabric pots in Southern CA.
This is my second year with figs (but over 15 years with tomatoes), and I will say that pulling any plant out of a fabric pot, is not easy.
Plastic pots will let you slide the young plants out rather easily if you wet it a bit, squeeze the sides a bit, and flip it to let gravity help you out. Fabric pots, on the other hand, have been messier to work with, and more difficult to remove plants with heavy roots.
I currently have most of my fig plants in plastic pots with one in a fabric pot. I’ve easily uppotted all the ones that were in plastic. The fabric one, which is a true 10 gallon one, I’m loathe to touch. One, it’s gross after a year of watering and feeding. Two, it’s heavy and unwieldy.
Not sure if I can leave my one fig tree in the fabric pot indefinitely since fabric pots are supposed to air prune roots. If so, awesome. Otherwise, I’m going to move it into a plastic pot when growth stalls.
Your mileage may vary depending on location, experience, patience, and sanity. For what it’s worth, my tomatoes always grow like gangbusters in them.
