Not all of them. Quite a few are in pots. I couldn't put them in the ground where I wanted because it's nothing but clay when I got down to about 3". Putting them there would definitely be a death sentence.
The basement is too warm at 63° and while the shed would offer protection from snow, ice and wind, it would probably still be too cold when the temp stays 20° or lower for long periods.
Thoughts?
