This is an update of an obviously productive sub-irrigated rain gutter garden installed on a boat dock.
Later this week there will be a small rain gutter garden at PS 133 here in Brooklyn. It will be part of a school garden that will include 69 tote box sub-irrigated planters (SIPs) and the beta test of 3 vertical gardens modeled after African sack gardens, but made from trash containers.
No paved surfaces will be broken to create this garden. It will grow on concrete and replace some existing top-watered raised beds that did not work very well.
Highly productive gardens like this could be in the yards of hundreds and hundreds of schools and row houses all across New York City and beyond. There is no need for digging into often-contaminated city soils.
All it takes to create gardens like this is the knowledge of how to do it and a modest amount of funding. In the case of schools, it could be crowd sourced funding
