We have one Chicago mother plant that we wrap here in NJ. If we have a cold winter it will die all the way back to he ground. Any figs that come from new growth won't have enough time to ripen before winter . That is why we try our best to keep old growth alive. We wrap it in burlap and loose wrap it with roofing paper. It keeps the burlap from getting wet and freezing. The looseness let's it breathe and avoid rot. All cuttings taken during the season are over wintered in the cellar in 5 gallon buckets. We produce cuttings using air layering lower branches. Learn something new each year.
