After searching and searching and almost buying new pots (Oh! The horror!) I came upon a local lady who was getting out of the business of selling used tree pots to tree farms. She had literally 1000s of pots in all sizes. She tossed in extras but I got this haul of mostly 5 gal pots for $40. Sizes range from a few 1 gals-50gals and everything in between. The last pot I bought was $17. It won't last as long as these!
When I inquired at Lowes, the guy told me "no" and looked at me like I had 2 heads. Shrug. I told him, "You mean, no, notvat THIS Lowes".
