Scarlett Randall and Bill Clark will give demonstrations on worm composting at the Market on Saturday. Scarlett has integrated worms into her elementary school curriculum and Bill is an avid vermaculturist—a person who feeds and cares for worms. At 10:15 am they will demonstrate the changing of the worms in a composting bin and the basics of worm care.

Worm composting is the process of red wiggler worms turning kitchen scraps into a rich, black soil. Red wigglers are smaller than earthworms and do not burrow deep into the soil. If you were to dig into a pile of leaves left over from last year, there would probably be some red wigglers at work. They could also be found in mounds of old straw and manure. Because the worms multiply rapidly and are unstoppable eaters, they have been “domesticated” and placed in containers for home composting.

Scarlett is a Kuna resident who teaches elementary school in Boise. She will be at the Market to show how she has built her fourth and fifth grade class curriculm around the red wigglers and their hearty appetites. The students studied the lifecycle, anatomy and the ravenous eating habits of the red wiggler worms. The kids collected and weighed the school cafeteria waste they fed to the worms. They also experimented with different worm habitats.

Plant cycles were also studied. The kids used worm compost to start plants in the classroom. Worm tea, a by-product of composting, was used to water and nourish the plants.

The class also read stories and myths of worms. They studied “Worms Eat My Garbage,” Mary Applehof’s book about her experiences with composting worms and recycling her kitchen waste. The kids also researched how schools in California are utilizing composting worms in education. They documented their research and lessons in individual booklets.

My husband, Bill Clark, and I have composting worms. The worms in the worm bin have eaten 50 gallons of kitchen scraps each year. They also produce one tray of worm castings and many gallons of worm tea. It is time to move the worms into fresh bedding. Bill and Scarlett will change the worms and demonstrate how to set up a new worm bin.

Fresh produce at the Market this week includes sweet corn, grapes, peaches, apples, green beans, blackberries, melons, tomatoes, pickling cucumbers, peppers and tomatillos.
