Three Sisters

 

The Three Sisters of Native American agriculture are corn, beans, and squash, grown together where they can complement each other and, when eaten together such as in succotash, they can complement each other nutritionally. The Three Sisters get on so well together that it’s tempting to ascribe their harmonious relationship to one of the many Native American legends describing it, ignoring the thousands of years of human trial and error, experimentation, and opportunistic capitalization on circumstance that played into the development of the relationship.

 

Corn provides a tall stalk for the bean vines to climb upon, and her deep roots help stabilize the soil and pull up nutrients from deep down. Beans fix nitrogen from the air, providing fertilizer for herself and her two sisters. Squash sprawls on the ground where her large, prickly leaves keep away some pests and provide a living mulch for her sisters, keeping the soil moist and inhibiting weeds.

The nutrients available from all three plants provide most of what a person needs. Add to that the capacity for all three to keep dried in storage through the winter, and it’s easy to understand how Native Americans in North America adopted them as the foundation of their diet. This Thanksgiving, along with hearing or reading some entertaining and philosophically informative legends about the Three Sisters, there can be great enjoyment in tasting one of the many recipes for succotash as part of the holiday dinner.

“Single Girl, Married Girl”, an Americana song from the Carter Family catalog, sung by The Haden Triplets on their eponymous 2014 album, produced by Ry Cooder. The song, the singers, and the producer all share deep roots in American music. For more of The Haden Triplets, view their NPR Music Tiny Desk Concert, where they lead off a four song set with “Single Girl, Married Girl”.

Most succotash (derived from a Native American word, like numerous others) consists of a base of corn and beans, leaving out the squash, but for autumn dining, and especially for Thanksgiving with its reminders of the autumn harvest and the debt of European immigrants to Native Americans, adding squash to a succotash recipe can only improve it for the season. The squash and its seeds will add many of the benefits a person could get from eating turkey, another native of North America, including tryptophan, the chemical many believe is responsible for a satisfied diner’s desire to relax on a couch after Thanksgiving dinner, as well as lazily escaping from kitchen cleanup duty.

Mulch too Much

 

 

As summer fades into fall, gardeners consider tidying their flower beds and around their trees and shrubs. Putting down new mulch can be part of this process, and it raises the question: How much mulch? Mulching two to three inches in total depth is plenty, making sure to keep the mulch from touching plant stems, and not piling up volcanoes of the stuff around trees. Any “professional” landscaping outfit or individual who does otherwise is acting out of either ignorance or the desire to sell more mulch, perhaps both.

Another consideration is whether to put down commercially produced mulch or wood chips. The term “mulch” can apply to organic or inorganic ground covers, such as pine bark, shredded hardwood, or stone. Wood chips are made from every part of a tree, and chips range in size from coarse chunks to finely ground pieces no larger than an inch. Gardeners should be careful to check the source of wood chips because they may have come from trees infested with beetles or borers, and if the chips have not been ground up finely enough or heat treated, then the insects may survive to cause further damage in new surroundings. Commercial wood mulch should not cause similar problems if the manufacturer has effectively screened it for pests, though gardeners should not apply it directly up to the foundation of a house, where it can serve as cover for termites already present in the soil.

 

A good rule of thumb to follow when applying mulch is not to apply it so thickly as to make it a heavy slog for the average happy garden gnome pushing a wheelbarrow.
