I have a small raised bed dedicated to my first Three Sisters growing right now. Just planted beans a few days ago now that corn has had a head start. Rookie gardener, but hoping for at least some visual interest if not production. The beans are supposed to fix nitrogen which helps the other plants, but does anyone know if this requires a year to pass where the old bean plant decomposes into the soil? Or is merely bean plant presence enough to share nitrogen?
