I’ve only grown it for 3 years (edit: it was growing at the site for 30+ years before I bought it, but they protected it in most years). The first year, I tried to protect it with cardboard, leaves, and a patched up tarp. That time, there was significant dieback, but some above-ground growth was still alive. I didn’t bother for the last two winters and both times it came through very well. But, it was the two warmest winters in the last 10 years, with the low being around +10F. Before that, the low has been anywhere from -9F to +1F. So, that could be a big part of why the Reservoir fig did so well last year (decent sized early crop around Aug 1st, as well as the usual September figs).
This winter, I see 6 different days that got down to single digits in the town with Reservoir (per Weather.com), with a low of +3F. So, it will be interesting to see how it does this year.
I checked Weather.com for another rental site that I have a Reservoir clone planted at (planted in July 2019). That town only got down to single digits once (+5F) and 10-14F a handful of times. Also the fig is planted with a couple feet of the building on the WSW side, so that should help it.
Further complicating things is that both towns are rather large, so it’s hard to say how accurate the weather.com data is for any particular location. Both towns extend 8-9 miles inland and the properties are within 1-2 miles of the coast, meaning that the temps may be a bit higher than the “overall” town figures.

And I see many are listing what they grow. I think it might be a shorter list if I just include what I don’t grow That list is basically just Sweet cherries (way too much trouble and I like the ones from the store better than the few I got long ago on my trees). I think there may be a few niche berries I haven’t tried (Aronia, Seaberry, Ligonberry, etc). And I tried growing Rhubarb, but it’s died several times. And I haven’t tried fuzzy kiwi, just the hardy arguntas, as I’m not sure if fuzzy kiwi will be hardy over the long term and have been hesitant to commit the space (and am not thrilled with the tingly aftertaste from kiwi). I am growing several muscadines though.
My main focus right now is on jujubes. While not always productive in our climate, some varieties and some trees have been and it is one of the few fruits here which can get 20 (or 30, and even 40 rarely) brix and not need any sprays. Some people complain they are too dry, but I think the best jujube are crisp, with an apple texture. And I don’t really like my fruit to be too juicy (like peaches with juice running down your wrist, etc). I’ve got a number of rental properties and I use jujubes as landscaping at them. Between the properties and my 1/2 acre yard, I’m around 100 jujube trees and always looking for more varieties to graft on.
