Honestly the best part is just starting with one thing you grow too much of, like herbs or tomatoes. You post on the neighborhood app that you have a surplus, and someone with a lemon tree or zucchini plants will show up. It builds a weird little local economy where nobody spends cash, just trades what they have. My neighbor and I do this every summer now, and my grocery store trips for veggies got cut in half. It takes the pressure off trying to grow everything yourself, and nothing goes to waste.
Last summer in my neighborhood, we had a similar swap setup that fell apart after a month because everyone grew tomatoes and no one had lemons. It sounds great in theory, but it assumes a balanced ecosystem of gardeners that just doesn't exist in most suburban areas. I mean, how many people are really growing enough surplus to make this a reliable way to cut grocery trips in half? It feels like another idealized version of community that works for a few but gets messy when you scale it beyond a couple of neighbors. Maybe I'm just cynical from seeing too many well-intentioned projects fizzle out.
Wow, @allen.cora, this reminds me of that Michael Pollan book where he talks about 'gleaning' communities. It really does build resilience (and way better than any app economy, honestly).
Ever seen a produce swap turn into a full-blown barter system? My block started with just trading herbs, but now we've got a rotating schedule where someone always brings citrus or leafy greens. @wyatt135, I get the skepticism, but once you get a few committed people, it smooths out. Last month, I traded my excess basil for enough lemons to last all summer.
