Hurry and bury them before they are completelly dead.You suppose to do it on Thanksgiving day.If you do not do it now the soil will freeze and will not be possible to dig anymore.i Was bringing some in my Garage on Thanskgiving day and still look dead at least the top buds do.We will see.Regards

Maggie and Herman, excuse my approximate language... translation.
The system of bury the trees (e.g. grape vines) in colder region of Europe was a demonstrate good system as cold protection to the less cold hardy trees.
The buried plant has to be covered by straw and than by soil.
For the easy tip of course it is easier if the plant is conserved in bush shape.
The worse system is conserve the plant outside in a simple pot, the soil on the pot has quikly the same temperature of the air.
Instead ON the soil of the ground, at deep of one foot the temperature drops very less.
Adult plant (if conserved in dimensions and shapes adapt to tip, are a lot more cold hardy than young ones.
About figs there are varieties less and more resistant.
Quite the cactus late fall in drougt (I think)increase the cold hardiness, (the wood of fig may collect a lot of moisture, being a plant of hot and drought desert).
Ciao, Sergio

Thank You Sergnic for the information. I did not use the straw but I will next year. I will also be looking for a hardy fig! I'm Sorry for the delay, but I could not login,
