garbage bags wouldn't be sturdy enough and why not just dig a hole in the ground and plant it? that'd work better, i dont even know what a trash bag would do differently
If you use a garbage bag the food and water stays within that bag so the plant is the only one getting fed vs the other where you are just feeding everything within reach of the water and the bag would also retain water better than without
You can dig but I would get the biggest bags you can and if you want a 12 foot plant you will need more than 5 gallons to promote growth properly
But thats just me
