The Three Sisters Garden is an intercropping method that involves planting corn, beans, and squash together. Each crop has a vital role - corn acts as a trellis for the beans, which provide nitrogen to the soil. Squash plants act as a ground cover, conserving soil moisture and suppressing weeds. This sustainable farming technique originated from indigenous Native American tribes and is associated with the Iroquois Confederacy. To start a Three Sisters Garden, prepare the soil, ensure consistent watering, and plant the crops in late spring to early summer. Harvest the corn, beans, and squash when they are ready.
