Composting Options Part Three: Indoors & Low Maintenance

In the 3rd part of our DIY composting series, we'll go over an easy indoor option that may be a perfect fit for those just looking to provide compost to a handful of potted plants or a small garden. Vermicomposting (composting with worms) can result in extremely rich compost. The worms are easy to obtain, easy to care for, and require less direct involvement than many other composting methods, making them a great option for anyone without a lot of time to commit to composting. This article won't go into depth on the intricate details of vermicomposting, but we'll give you enough info to get you pointed in the right direction. There are additional resources listed at the end of this article.

  • Inexpensive

  • Easily assembled, whether from a kit or with existing materials

  • Lightweight and easily moved when empty

  • Can be easily maintained indoors

  • One of the least time-intensive composting methods

  • Worms create extremely rich, high quality compost


  • Limited capacity / limited output

  • Poorly maintained worm bins can result in strong odors

  • Poor maintenance can kill the worms

Perfect for:

  • Small households

  • Anyone with minimal compost needs, such as those maintaining potted house plants and small gardens

  • Anyone looking for composting options that don't require strenuous activity

  • Anyone seeking extremely rich compost with minimal effort

Not ideal for:

  • Anyone spending long stretches of time away from the house. Though low maintenance, worms do require feeding and watering or they will die.

  • Anyone whose household creates high output quantities of compostable items. Worm bins will fill up quickly, which may require additional bins or a different composting method.

  • Anyone without a garage, shed, or other temperature-controlled space AWAY from the main living area of the house. Worm bins may be build for indoor storage but they do carry some odors that are best left away from your living space.

Why we love Vermicomposting:

It's hard to compete with the natural composting abilities of worms. A well maintained worm bin can create compost with unmatched nutrient density and richness. Large scale vermicomposting operations exist around the world, creating much of the "chocolate cake" like compost that's widely available in nurseries. Vermicompost is generally extremely high in moisture content as the worms act as food processors, turning all of the inputs into a well blended and processed output that is hard to match without extensive equipment and labor. Vermicompost is also great for producing compost tea, as it's often finer than the results of other composting methods, leading to quicker dissolution when added to water.


The work required to operate a successful worm bin takes place in the beginning and the end. Setup is often the most time consuming part, as many people choose to build their worm bins from existing plastic tubs or similar household items. This can be avoided if you're willing to purchase a worm bin, but it'll cost you. There are several commercially available worm bins that can be installed in just a few minutes, but many people find the homemade options so simple that they choose that route. The best method is the one you'll actually use, so pick whichever method you prefer.

Once built, add in a mixture of soil and shredded paper a few inches deep. Add water to create a moist substrate, but not enough to result in puddling. Add your worms but wait a day or so before adding any food scraps. Once you're ready to add in food scraps, do so only once per week. Collect scraps in a container and put them into your worm bin all at once, so as to minimize the stress on your worms. They enjoy their privacy.

Occasionally, you'll notice foods that your worms don't like. Remove those scraps and avoid feeding those items to your worms in the future, as their tastes aren't likely to change all that much. Eventually, you'll have enough compost to harvest. In the weeks approaching harvesting day, begin feeding on one side of the bin. This will drive worms in that direction, allowing you to harvest easily from the other end of the bin. This process can be time consuming, as it is important to avoid damaging your worms and to minimize the number of worms removed from the bins. If you ever find that your bin is overpopulated with worms, ask around for neighbors that may be in need of worms for their bins.
