Our three sisters planting of squash, corn, and beans are growing like crazy. All but the beans which seem to have been set back by something munching on them. The water is applied with drip irrigation under this crop. Jose gives them a deep watering every week which encourages the roots to go down deep. Frequent water keeps the roots near the surface so the roots do not explore the soil profile thoroughly. I believe the more soil the plant roots explore contributes to an enhanced flavor.
