Greg,
I can't tell you how many times the wind blew off my porch some pot full of plants. Don't throw those pots away. I always glue mine back together. I use 'Gorilla Glue'. The brown bottle stuff. Dries like expanding foam, but really hard. It likes water so you don't have to dry your pots before glueing. Cut excess glue off the next day or it will be very hard to do afterwards. Almost anything that breaks, I use this stuff.
And don't get any on your hands. It takes a long time to wash off.
