Successful vegetable raingardens need to both retain stormwater and produce vegetables. We did a greenhouse experiment with two different substrates and methods of stormwater application. Overall, potting mix produced bigger plants and greater yield than loamy sand. Bigger plants also had greater transpiration, which meant greater stormwater retention. A raingarden with potting mix and surface watering was optimal for food and stormwater retention.
