We have a garden and have, in the past, tried to grow some veggies especially when the kids were younger when that sort of thing was par for the course. Unfortunately, the soil quality is so bad (it's London after all) that anything that did grow was more akin to a Bonsai version of itself. Not only that, but more frequently than not it was diseased.
I do make planters for clients so perhaps, when the apocalypse is over, I should make some for myself for the second apocalypse when it comes.
