As Ron says, you could still drill holes in the bottom and place the tanks
on brick stacks. This is actually a very good idea because, in winter, the
rootball will be protected from the icy ground.

I'm just trying to ponder the physics of how, when it gets really
cold, the small mass of the tank will stay warmer than the large
mass of the ground?
