I moved most of my potted plants into the unheated shed now that night temps are consistently below freezing and the winter winds are blowing through the yard. I have a small thermometer in the shed to keep an eye on temps. Usually temps range from the upper 20s to 40s, depending on the weather. But last winter it dropped into the upper teens inside the shed for about 72 hours. Although it sometimes gets that cold in there, the plants are out of the brisk wind that can easily desiccate the young plants.
Here are my dormant young fig trees. They are in 1-gallon plastic nursery pots. They will survive the coldest of temps inside the shed now that they are "sleeping". Only occasionally do I add some water to the pots to prevent the roots from completely drying out. They will stay in here through the winter until I see the buds starting to break in the spring, then I will move them outside. My older fig trees (3-5 years) are planted in the yard, unprotected other than with a thick layer of straw mulch around the roots, and they should be fine as well. They seem to get more cold hardy with age.

The figs aren't the only potted plants in the shed. I also moved my dwarf calamondin orange tree in there as well (the lemon and lime tree are inside my house because they are very cold sensitive).

Last winter I unintentionally neglected this one and it survived even though temps inside the shed were under 20F and remained there for almost 3 days. Most people don't realize how cold hardy calamondins are if removed from the winter wind.
I'm currently in the process of building a large compost bin and arranging my setup for starting seeds with a heat mat and fluorescent shop lights. I'll post more about these things soon. Until then, I'll be dreaming of warmer temps and fresh veggies and fruit.
