Q.Garden Container Pots
I have many many pots that I use in the summer (perhaps 40 or 50. . . . small and very large). They are glazed on the outside but not the inside. I am looking for a creative way to cover the pots so that they are rainproof and, thus, hopefully will not freeze, expand and break. Moving some of these pots would be extremely difficult. Mostly I want to leave them on the deck and in the yard because they are so colorful! And I prefer not to empty them, at least for now. I have been trying to come up with a creative and cheap solution. Any thoughts?

Without glazing the entire pot, moisture will get into the porous clay.
