My plastic barrel container garden

[Kali]

4. I have seen metal drums cut longwise for animal feeders but for some reason

never thought of cutting plastic ones that way.

great idea. we probably don't get enough rain to make the shallower depth work (would need to water twice per day in June). I have cut those the other way to use for water troughs and they invariably start to taco in and need a brace across the top to kep the opening round, but dirt holds them OK. have used for planters too.

sometimes you can find those things pretty cheap or even free if you feel like cleaning them.
