Worm Farms

May contain: soil

Worm farming, also known as vermiculture, is a simple way of composting organics in the comfort of your own home. A sturdy bin with a lid, bedding material and worms are all that is needed to start your “farm,” which can be kept indoors or out. Hungry worms make quick work of leftover food scraps, and over weeks and months, transform them into fabulous, nutrient-dense fertilizer (a.k.a. “worm poop”) that can be used for household plants or your outdoor garden. Ready-made farms are available for purchase online, though it is no less effective and much cheaper to create one.

The Worms

Not just any worm will do for a worm farm; red wigglers are best. This type of worm especially thrives when eating decaying organic material. Red wigglers can be purchased local at Black Diamond. In addition, the IWMA school education program sponsors worm beds at local schools. 

For optimal results, worms are fed equal parts “greens” and “browns,” as it is called in the organic gardening world. These designations refer to the carbon to nitrogen ratio of the material, not the actual colors. Feeding guidelines are as follows:

  • Yes:
    Fruit, vegetable, bread, coffee grounds, tea bags, dead plants/leaves, egg shells, uncoated paper, napkins, coffee filters
     
  • No:
    Citrus fruits, onions, garlic, leeks or shallots, meat, fish or poultry, eggs, dairy, greasy food, salty food, prepackaged/processed food, glossy magazine paper or coated paper
    • Any food items that can't go in your home compost system don't need to go to the landfill: you can always put all food waste in your curbside organics bin!
