I started container gardening 25 years ago. Mostly 5 gallon buckets. Works well with tomato and pepper plants. I can move them around to get more or less sun. For shallow root plants I use rectangular containers for green onions and melons.
Initial start up, I had to purchase 6 buckets, tomato cages and stakes. Each year I put new soil in the buckets but re use the cages and stakes. All done in a suburban back yard.
Thank you! Stay tuned for next month’s thread! :)
