Outdoor worm composting

If you want to get started with outdoor worm composting, you’ll need the following to get started:

  • Worm bin – You can use shallow stacked bins separated with screens. The worms can move up layer by layer as they have digested the vegetable and other organic scraps. Or, you could use one large worm bin with a lid. This worm bin has drain holes on the bottom and ventilation holes on its sides.
  • Carbon bedding material – Outdoor composting requires a steady balance of carbon and nitrogen. Carbon bedding materials are an important food source for your composting worms. It also controls odor and moderates moisture levels in the compost bin. Dry leaves or shredded paper bags are excellent carbon sources for outdoor worm composting.

It also helps to lay a mulch of organic material on the soil’s surface. Sufficient mulch thickness will prevent you from disturbing earthworm burrows and protect the moisture in the soil, supporting worm activity.

Avoid pesticides such as Sevin, Malathion, and Benomyl in your garden, which can adversely affect worm populations.
