I did some gardening in every cheap apartment I lived in as a broke grad student in the East Bay. Yeah, landlords aren’t going to do it for you, but that doesn’t have to stop you. Planting a small garden can be pretty cheap and is a huge improvement to the experience of living in most rentals, even if you’re only there for a year or two. Even got a couple of my landlords to let me deduct material costs from rent.
