I agree- 2 figs isn't much, but I was thrilled to have them ripen in January.
I make most of my own, with a mix of pine bark, perlite, leaf compost, and turface. But I don't remember the ratios. I think it was a fairly good draining mix and since it was at my desk and I passed it each day, I was pretty good about remembering to water it. Usually each Mon/Wed/Fri.
Here's a picture of it now, with Tomatoes and strawberries in the background.
One of the risks with protecting figs outside is animals. Something completely ate the base of my Hardy Chicago this past winter. So far, this was the only outside fig which has produced fruit. When I pulled away the leaves, I only found a single stick. And it wasn't attached to the ground. I didn't have much hope for it, but I stuck it into a random pot in the yard (it had Rose of Sharon in it). Strangely enough, the fig eventually took, so I have a new Hardy Chicago to replace the old one.
These other figs all overwintered (under some leaves) without issue. The two on the right were planted August 20th, 2016, while the one on the left was maybe a month earlier.
