Re: What kind of fig does well for you?
My fig ‘bushes’ or clumps have enough space so as not to be compeating with anything ... but I don’t feel they’re very invasive... And as mentioned, they can, and should be pruned. There’s an interesting method to pruning them though, as they’ll produce fruit on the previous years grown, removing that growth can also remove your next crop!
I know a fellow who’d planted one of my Brown Turkey starts in a massive ‘outdoor’ ceramic pot …at least 25 gallons of soil. But, it was too big to move. So during some very cold weather in East Portland a few years ago he lost it to freeze damage. So if you hadn’t taken your fig in during the winter – it may have suffered freeze damage as the soil will freeze in from the sides as well… Or in your case, maybe just enough to have ‘stunted’ it.
If you do haul it into a garage or warmer place during the harsh cold, I’d do the same this year, then plant it ‘next Spring.’ That would lessen it’s chances ‘one more year’ of freeze damage... Likely no big deal, but why do something today that you can put off till tomorrow
