Best Worm Composter Reviews in 2018

Composting is an excellent way to grow plants in the most natural way. The most common materials used for garden composting are wood chips, kitchen scraps and animal manure. But have you heard of worms being composting source? This process is referred to as “vermicomposting”. In this best worm composter reviews in 2018 guide we will take a closer look at this method.

What is Vermicomposting?

This garden composting method uses the usual organic materials but with the addition of earthworms that eat the leftovers and help break down the materials into nutrient rich soil fertilizer.

Vermicomposting is a win-win situation—your kitchen scraps, grass clippings, and leaves are recycled while providing a home for the worms. You don’t have to buy expensive plant fertilizers to feed your plants, so you save money as well.

To be successful in vermicomposting, you need composting bins or worm composters. These come in many shapes, colors, sizes and forms. Because of the numerous options, choosing the best one may seem like a daunting task. To help you choose faster and better, let’s discuss the important factors to consider before buying a worm composter.

What to Look for when Buying the Best Worm Composter

Here are the factors you may need to look out for when choosing a vermicomposer:

  • Drainage—choose one that has a decent drainage which features a spigot so that it is easier to take the earthworm tea out. If there is too much liquid from your kitchen scraps, the worms can drown.
  • Composter size—your household organic waste depends on how big your family is and how much food you consume on a daily basis. You may need a bigger bin if yours is a big family, so that there is enough space for both the worms and the scraps.
  • Harvesting—retrieving the compost means that you would also need to remove the worms and the food, which can be rather messy. If the composter has a nice harvesting feature, you can easily retrieve the compost without disturbing your worm colony.
  • Materials—it is important to find bins that will survive extreme weather conditions because you wouldn’t want to lug the entire compost bin indoors during the winter months. Choose a sturdy bin made from resin or plastic that is designed to withstand heat and freezing to ensure that your composter can stay outside throughout the year.
  • Ventilation—worms work best when their environment is airy and well ventilated. Choose composter bins that have holes through it and also ones that have domed lids to make sure that your worm colony gets enough air.
  • Shade—try to avoid bins that allow light inside because worms do not like sunlight, so an opaque compost bin that blocks light may be your best choice.
  • Added features—there are composters that feature trays which separate the compost materials from the worm castings so that harvesting is made easier. There are even composters that collect “worm tea” in small trays. It may cost more but these extra features will greatly help in minimizing maintenance.

With these factors in mind, you can have a more well-informed decision when you buy a worm composter bin. To help you further, we have listed and reviewed the top worm composters for 2018 below.
