In early spring, save a section of your garden that is at least 4 feet wide for your three sisters garden layout. At this point you can dig up the section and keep it weed-free, or you can pile compost and other soil amendments into a mound that is 12 inches high to prepare the “raised bed” you will plant your seeds in.
In late spring after the last frost has passed, sow eight corn seeds in a circular pattern in the center of your mount. Space your corn seeds about 6 inches from each other in the ring pattern you have started. Pat down the soil around the seeds and give the mound a good drink of water and keep the soil moist until the corn germinates in the mound.
A couple of weeks later your corn should be sprouted and somewhere between 5-10 inches tall if everything has gone well. At this point it is time to plant the beans. Take about four beans and evenly space them around each corn stalk. Use your finger to push the bean seeds about an inch below the soil’s surface. Again, water your mound and keep your bean seeds moist until they germinate.
A week after your beans have sprouted and began to grow up the corn, take 6-8 squash, pumpkin or melon seeds and plant them evenly spaced outside the ring corn and beans. As the squash vine grows, help it along by directing the vines around the mound and up into the center ring created by the corn.
