Indoor Composting with Worms

Worm FactoryThe Worm Factory Worms in the house? Yes, as long as they help with the housework.

Our new Worm Factory worm composter houses 8,000 to 12,000 worms who will work tirelessly, night and day, turning kitchen scraps into rich compost for your garden. And worm compost has 10 times the nutrients of regular compost. Once established, the worms will compost 5 to 8 lbs. of kitchen scraps per week.

People have been composting in worm boxes for a long time, but this four-tiered system makes the process efficient and neat. Worms start in the bottom tray and migrate upward as they go, leaving behind tray after tray of rich compost. A reservoir at the bottom captures “worm tea” — an ideal, odor-free liquid fertilizer.

3 Reasons to Try Worm Composting

Composting kitchen scraps in a worm bin is easy and rewarding. Even if you already have an outdoor compost bin, having a worm bin makes good sense. Here’s why:

  • Worms Work FAST: Worms can convert most kitchen scraps to finished compost in less than two weeks.
  • Worms Work ALL WINTER LONG: Keep a worm bin in your basement, garage or pantry (above 55 degrees and below 80 degrees F) and your worms will keep making compost right through the winter months.
  • Worm Castings are RICH: Top dress any of your indoor or outdoor plants with some finished worm compost and watch what happens. You’ll get better results than with any commercial fertilizer.

    The idea seems great… I agree that compost is a really important part of gardening, but maybe I am being silly here… wouldn’t the compost smell? Is it really all that pleasant to have it indoors?

    My first question is same as James F asking wouldn’t there be an odor? Also, in the spring, can you put the worms outside into the outdoor composter?

    Hi James and Patti:

    Yes, when warm weather returns, you can move the bin outdoors in a cool, protected area.

    Does it smell? I just talked with Mike in our Vermont store. He has a lot of experience with worm composters. He says:

    There really isn’t much odor unless you add lots of onion, or too much raw broccoli. Chopping or putting these things through a blender before adding them to the bin will make it easy for the worms to eat them more quickly, and prevent odors.

    I fill my empty top tray with shredded newspaper and keep a 1″ layer on top of the scraps in my working tray. In addition to absorbing any odors, this also helps deter fruit flies.

    I try it and no smell. I made compost when outside was snowing so low temperatures.

    Great idea! Shouldn’t be much of a smell like others have said.
