Temps that cold are normally not an issue here either; at least they haven'et been for several years now. The heat lamp and tarp/tent weren't enough, I think. I checked on them and looked more closely, and I can already tell some are ruined. The bud at the top of the dormant cuttings are already that frozen brown color common after hard freezes, and the cuttings themselves have a slightly ridged, shriveled look to them. Sigh. At least I can try again. I have several large trees.
I think I will just go ahead and take more to be on the safe side. The cups are already filled with soil so all I will have to do is take cuttings, trim, put hormone on and stick them in the soil. I guess if it gets that cold again, I'll just pack them all into the house and sit them around everywhere, ugh.
We have had really good luck selling them at swap meets and other 'junk' venues and I wanted to have more to sell.
My mother trees, as I call them, are Green Ischia, Black Misison, Kadota, Celeste, Magnolia, Marseille, Hardy Chicago, Fanick's Blue Giant, Red Gold, Banana, and several other varieties in large and medium pots. I'm a fig addict....
