Since it became a pet cause for the Obamas, we have heard much over the last year or so about the wonders of gardening. But we haven’t heard quite as much about what to do if, say, you want to do some gardening but have no land or roof where you can do it. Enter a new service called WePatch.org, which matches people who want to garden with people who have land to do it on. It’s a pretty brand-new thing, so there’s no listings for Philly yet… but there should be tons. We like this so much. It is already making us feel good.
