Using what is basically a moving blanket insulated low tunnel with a very small space heater inside. Basically 10’ conduit bent to a 4.5’ tall and 2.5’ wide arc. Placed over top of that is 6 mil clear poly - which makes a low tunnel. Then for winter protection I cover the whole thing with some Harbor Freight moving blankets (they are decently thick and about 5.5 lb ea.) and then a tarp. The small heater (or pipe heating cable in the future) is managed by a temperature controller to keep the temperature above 20°F.
The plan is to grow my figs in a row and then cut them down to 4.5’ when they go dormant and get hit by 2 or 3 frosts. Then about 4-6 weeks before last frost remove the tarp and moving blankets and start keeping the temps above 45°F to get them waking up from dormancy.
