The black tree size pots I got from a neighbor who does fences, mowing and landscaping.
My neighbor knows to save those for me. He also has given me bunches of the 3 gallon size, I won't run out of those anytime soon.
When I needed a bunch more this spring I got some from Walmart, 20" size. You can go to Walmart.com and look at them. They are the Bombay planters.
