>>2473870I have a large bush of peppermint on my balcony.
Started with a large plastic flower pot. Every time i had some cuttings or dead potted plant, i put it into the pot. Eventually it was full.
I bought a pot of peppermint in a super market, which is a thing here, you can buy thyme, basil, all kinds of fresh herbs in a pot in most supermarkets here.
Eventually i picked it clean and threw the pot, minus the plastic of course, into my "waste" pot and went away for two weeks for work.
Came back and the peppermint survived and took over the pot.
