Hey...I think it's just wonderful you are trying to grow anything at all on a small space. I think everyone should be trying to grow a little something, no matter how small a space they have...just makes sense to do so. Over in the UK folks have allotments, some very small, some a little larger, but seems like they all are limited on space, water, what they are allowed to grow or have, etc., but many of those people rent those spaces through several generations of their family, just trying to grow something fresh to eat.
We are very fortunate here in the states in the amount of land we have. When I drive by churches in town with sweeping, wonderfully groomed lawns it always makes me wonder why they don't turn that into a garden/food ministry instead of trying to get folks to mow it every week.
