I had one years ago. It finally was broken because my helpful neighbor kept thinking the pot fell over and kept setting it up. I told her it was a spiller pot and it was suppose to laydown.
She was s senior and would come and visit me and just could not resist setting that pot up. She just loved to come across the street to visit my gardens and talk to me.
Okay I got that out. :blushing:
I filled it soil wise as Caroline described. I planted mine with Hens and Chicks and would put coleus in it in the summer for color.
I am not sure if the pots you have are terracotta but if it is......It will dry out very fast. The only thing I could get to live in it was succulents. So if you are looking to plant with something that likes moisture you will either have to line the pot with plastic, or put some of those soil moist beads in the pots if they are terracotta.
