I live in a city, so the growing region is by proxy the closest supermarket. My apartment does have an unattended garden but I'm not quite sure what I could do with it. Every spring there's plenty of growth but some dickhead always mows everything down if summer doesn't make everything dry and uhm.. groundy?

I'm assuming they keep coming back because (A) They hate that mowing dickhead (B) They have some pretty darn long roots there. Seeing as plants don't have emotions B is the right option while A is more wishful thinking.

I have a nice pot of peppermint which the ground looks dense like a bus full of people and it still managed to grow some despite how dense the ground looks and summer fighting it with a water drinking competition.

TLDR: What options do you think a city guy has?
