Gardening in Stock Tanks
OK, let's see if I attach this photo correctly.
I was recently at Walt Disney World, during the International Flower and Garden Festival. They had a section for the home garden, where they had the following small stock tanks, with veggies and flowers growing in them. Everything was doing very well, even in those hot and humid conditions. They had other ones with eggplant, peppers, and it seems like bush cucumbers.
