It is said that over 50% of the waste we produce in our homes is compostable. Why send it away to landfill when much of it can be turned in to black gold, vermicompost. It’s a win-win situation, you help save the planet and your garden will thrive. In addition, researchers at Cornell University discovered that the nutrient rich vermicompost helps suppress plant disease.

How Do Worm Compost Bins Work?

Worm composting, also known as vermicomposting, is a process of using worms to break down organic material into nutrient-rich compost. Worm compost bins are specially designed containers that house the worms and the organic waste material.

Here’s how the best worm compost bins work:

  1. Setting up the bin: A worm compost bin typically consists of a container made of plastic or wood with holes for ventilation. The bottom of the container is lined with a layer of shredded newspaper or cardboard to absorb excess moisture.
  2. Adding the worms: Next, you’ll need to add composting worms such as red wigglers to the bin. The number of worms you add will depend on the size of your bin and the amount of organic material you plan to compost.
  3. Feeding the worms: Worms are voracious eaters and can consume up to half their body weight in organic material every day. You can feed your worms a variety of organic waste such as fruit and vegetable scraps, coffee grounds, eggshells, and yard waste.
  4. Maintaining the bin: To keep your worm compost bin working efficiently, you’ll need to maintain the right condition. This includes keeping the bin moist but not too wet, adding bedding material regularly, and avoiding adding materials that the worms can’t digest, such as meat or dairy products.
  5. Harvesting the compost: Over time, the worms will break down the organic material into nutrient-rich compost. You can harvest the compost by removing the top layer of bedding material and using a screen to sift out the compost. The compost can then be used to fertilize your plants and gardens.

The best worm compost bins work by creating the optimal conditions for the worms to thrive and break down organic material into nutrient-rich compost. By following the steps above, you can create your own worm compost bin and reduce your carbon footprint while improving your soil’s health.

Use the proper worms in your compost bin

You’ll also need to use the proper worms in your worm bin. Many people attempt to put common earthworms in their worm bin and quickly end up with a rotting mess of food scraps. Red worms, aka red wigglers, are the most common type of compost worm. They readily feed on food scraps, paper, coffee grounds, and more. Red wigglers eat half their body weight per week. More worms, more compost.

Easy to maintain – Worm composting is relatively low-maintenance and requires only basic upkeep such as feeding the worms and keeping the bin moist.

Things To Consider When Choosing The Best Worm Compost Bins

Size/Capacity

The size of your worm compost bin will depend on the amount of organic waste you generate and the space you have available. If you generate a lot of waste, you may need a larger bin to accommodate it. However, larger bins take up more space, so make sure you have enough room before purchasing.

Material

Worm compost bins are available in various materials, most commonly fabric or plastic. The plastic bins are lightweight, affordable, and easy to clean. If you choose a fabric worm composter, be sure it’s made from a durable material. Consider the pros and cons of each material and choose the one that best suits your needs.

Ventilation

Worms require oxygen to survive, and proper ventilation is crucial to prevent the buildup of toxic gases and odors in the bin. Look for bins that have adequate ventilation, such as air holes or mesh screens, to ensure a healthy environment for your worms.

Drainage

Proper drainage is essential to prevent excess moisture from building up in the bin, which can cause the compost to become waterlogged and may harm your worms. Make sure your bin has adequate drainage holes or a spigot at the bottom to remove excess moisture.

Ease of use

Look for a worm compost bin that is easy to set up and maintain. Some features to consider include easy access to the compost, removable trays or bins for easy harvesting, and a lid that is easy to remove for adding food scraps. Single bin types have one compartment that can be opened from the bottom to extract the worm compost.

Durability

Worm composting is a long-term investment, so you want to choose a bin that is durable and can withstand regular use over time. Look for bins made from sturdy materials that are designed to last.

Cost

Worm compost bins can range in price from relatively inexpensive to quite expensive. Consider your budget and what features are most important to you when making your selection. Cheaper bins may lack some features or durability, while more expensive ones may come with additional features and better build quality.

Compatibility with your composting goals

Worm compost bins come in various types, each with unique features and functions. Some bins are designed for indoor use, while others are better suited for outdoor use. Others may be more suitable for certain types of food scraps or garden waste. Consider the type of composting you want to do and select a bin that aligns with your goals.

Final Thoughts

If you’re looking for a single bin system that’s easy to use and has a large capacity, we recommend the Urban Worm Bag. While the Hungry Bin has the largest capacity, the price may put off many gardeners. If stackable worm composters are more your thing, the Worm Factory 360 is the best bang for the buck. For a smaller stylish indoor system, we recommend the Essential Living Composter which comes in several color choices and doesn’t look out of place in the kitchen.

We operate two different worm bins, one indoor and one outdoor. The outdoor system we use and love is the Urban Worm Bag. It has a large capacity and doesn’t involve shuffling a lot of trays to retrieve the vermicompost. Indoors we use the Essential Living Composter. We find that using both systems is ideal and gives us a place to keep our worms until the end of winter while still producing worm castings.
