Once upon a time in the Americas, long before colonization of Europeans the people of the land were creating "Sisters Gardens"
The Ingredients of a Sisters Garden" are:
NonGMO, NonF1 Hybrid, Maize aka Corn.
NonGMO, NonF1 Hybrid, Squash, this does include pumpkin.
NonGMO, NonF1 Hybrid, Beans
Long ago, they learned that the beans can grow up the maize and give the beans support. The beans fix nitrogen, but also more importantly, they learned that the corn & beans together when ate gave a more complete diet. Corn lacks the amino acid Lysine and tryptophan. , but beans have them thus making a complete diet.
Corn was also used in healing besides food. Corn silk especially known for this amongst many tribes.
Squashes were added as living mulch to deter weeds, and the prickly hairs are hated by a large amount of animals. However, in the American Southwest the Anazazi & Tewa tribes had a 4th, and important sister.
Cleome serrulata, aka Rocky Mountain Bee Plant is used as insect attracting, hummingbird attracting, but also it is a permaculture plant with multiple uses. It also has uses in medicine, dyes, and food. Rocky Mountain Bee plant, has 4x the RDA value of vitamin A in a mere 1/2 cup of greens.
There are no known other ingredients for Sisters Garden be they heard from elders talking story with me, or via research on the internet and books.
For many tribes, the creation of these gardens were done with ceremony, and are always regarded as something sacred. As sacred as all life is held, as sacred as a person in church, temple, or Mosque communing with their deity.
There are numerous planting instructions on the web for this style garden. However basically, they all start with the Corn being grown in center. Beans are planted around the corn, and a week after the corn starts growing is generally when the squash is added to the outer ring.
