Yes, you can create a vertical garden planter from a 55 gallon plastic barrel that does not take up a lot of space but does grow a lot of fruits and vegetables. It can grow over 40 different plants at one time, be portable on wheels, have a worm tower down the center so it creates it’s own fertilizer while getting rid of kitchen scraps.
You can make this vertical garden container yourself fairly inexpensively….. the biggest cost is buying the actual 55 gallon plastic barrel.
If you are asking, yes these are the same 55 gallon plastic barrels that people use to store water in case of an emergency or natural disaster.
Please make sure that no chemicals were previously stored inside of the plastic barrel.
