Worm Composting Bin

Are you looking for a fun way to turn your garbage into gardener’s gold? Do you want a pet that doesn’t bark, scratch or need a sitter while you’re away? Worm composting may be just the thing.  Metro Natural Gardening Expert Carl Grimm showed us how to set up a worm bin and use the compost as an all-organic fertilizer:

It’s as easy as 1-2-3-4!

• Get some worms from a compost pile or nursery.
• Don’t use regular earthworms or nightcrawlers – they won’t like living in a bin.

• Set up your bin – a plastic or wooden box.
• Build or buy a bin that’s rodent resistant, with a lid, floor and no holes bigger than a ¼ inch. Make sure there are some holes for ventilation.
• Put your bin where it won’t freeze or overheat. That means in the garage or the basement for winter.
• Use bedding in the bin: shredded, moistened newspaper with a handful of soil works great. Fall leaves or coconut coir also work well.

• Feed and maintain your bin – it’s not rocket science.
• Fruits, veggies, coffee, tea and eggshells are all good. Meat, dairy, fats, grains and breads may attract flies or rodents.
• Maintain moisture damp as a wrung-out sponge. This keeps things smelling sweet and earthy.

• Harvest and use your worm compost as an organic fertilizer when it looks like dirt.
• Worm compost helps your plants thrive without polluting fertilizers or toxic pesticides.
