I live 19 years in Orlando. I did the same thing there as I have to do here in SC. I acquired lots of those black plastic pots that landscapers get plants in. I cut the bottoms out of the 4 gal pots and bury them to within about 2” from the top. Take the dirt out each fall after their done and put it in black plastic garbage bags. Lay them out in the sun to bake. Next spring put the dirt in a wheel barrow and mix in some black cow and put back in pots and plant.
...good idea!
Thank you.
