Last evening, I stumbled across an article on GardensandCrafts.com detailing the process for building terracotta pot towers… and fell in love with the idea! It all sounds so brilliantly simple too. First, drive a 1/2 inch diameter rebar rod two feet into the ground. Then, thread terracotta pots through their drainage holes (each resting atop the previous pot as pictured).

I fear that the upper pots will sink into the soil base recommended by the original how-to . Otherwise, I will be constructing a beautiful tower of my own by the book!
