This is my trick for saving soil and recycling a generic plastic pot. When I am transplanting new flowers or re-potting plants into a larger pot I will use an old plastic generic pot and turn it upside down in the larger pot. You still get drainage and lots of room for the flowers or plant to grown while saving soil and recycling! I even in this case put my larger pot into an even larger pot. Finish off with a little moss and no one is the wiser! Voila! Save your self some soil and recycle! Love it!
