What Is A Worm Composter?

If you are new in the field of composting, you probably know nothing about the worm composting.

Worm composting is a savior of the traditional method where you had to keep the compost outside of your garden and wait to use the hot temperature. Since this takes such a long time, the worm composting method is the best option.

It breaks down the compost in a fast and efficient fashion.


It works when you let the worms feed on the waste and then poop to form the worm casting. This worm casting is valuable to your plants. So those who have a worm farm benefit a lot from this.

You should wait for it to form a colony, then feed them off your kitchen food wastes together with the papers and cardboard. After they process or digest it, excretion is a must. The casting is what you will use as fertilizer on your gardens.

This is a vital cycle where humans provide the home for the worms and feed them with the waste. You then wait for processing. When the worms poop, that is the fertilizers for your garden.

Why You Should Use the Worm Composter

The best natural fertilizer

If you have ever used this method, you know what we are talking of. Some industries focus on this process. The essence is to produce the worm casting, which is powerful and globally acceptable fertilizer.

So, if you have your worm farm, you will produce the fertilizer for free. Remember, buying the worm casting every time will cost you more.


Today we are looking for any method that will reduce the waste and therefore come up with a perfect by-product. Thus, with this method, you won’t need to send the waste to the landfill anymore. This is one easy way of recycling waste.

Its hard to make fertilizer traditionally

Typically, people would collect the waste and keep them in a compost garden waiting for it to cure. With worm composting, it consumes lesser time to breakdown the waste.

You will also grow fond of your worm colony. Maybe not the same way as your dogs and cats, but you will love the worms.

They work on compost through the year

If you place the composter in the right temperature and place, the worms will work continuously through the year. Avoid the disturbance as well. You will continually receive the casting for your garden. Find a place where it will work undisturbed for effectivity.

The Buying Guide

Of course, when you are convinced to buy the worm composter, there will be a few things to consider.

Where will you put it?

There are two parts of your home that you can put the worm composter indoors and outdoors. You must know where you wish to put it so that you buy the right material.

If you are interested in placing it within the house, know where you will place it in the house. Do you want it to be in a hidden part of your indoors or as part of the décor? If you make it visible, you should make sure you buy a sturdy and colorful bin.

Also, you must consider the odor from the composter and how you intend to handle it. Remember, the worms are handling mostly food waste, and that means they will somehow stink.

Do you want it outdoors? Choose the one that will fit easily in your garden. You can make it invisible by growing shrubs around it.

Consider the material

In both cases, the material used matters because you want the composter to stand the test of time. Even if you have it indoors, it should look sturdy and stand mis-handlers. If you will keep it outside though this is a major factor of concern.

The material should be one that can stand the different weather patterns. This is because we experience different weather patterns throughout the year.

Easy maintenance

We all agree that most of the composters are easy to set in the household. It’s as simple as creating a bed, getting the worms in the bed, and giving them the waste food to start processing. You should know how long it will take looking after the worms.

Also, know the cost of checking the composter and repairing it. I like those that you buy once and forget about maintenance because they are high-quality kinds. Remember some times you will need to recycle the bedding in a cycle.

Easy to harvest

Notice that you don’t always have to buy the composter, you can use the bucket and drilled holes to make the drainage. The problem with this is that you will have to do everything manually. You will separate the worms and the casting formed.

Also, you need to separate the remaining waste. If you, however, buy the commercial alternatives, then you don’t need to disturb the colonies. This way, they will reproduce faster and make even more castings fast. Therefore, the commercial one is ideal.

The drainage

This is vital in the composter. It’s especially true when using wet fruits and veggies. The process often produces the worm tea, which is also called leachate. The worms don’t work in a moist environment, and that’s what the leachate creates.

Therefore, you need a method to get rid of the leachate. A spigot is one such method that caters for the liquid. It collects it, and you can then mix it with water on a 50/50 then sprinkle it on the garden.

Is it expandable?

We all start with small families, but sometimes human families multiply. When this happens, you will have even more waste. Therefore, you need a larger composter to break down the compost.

If you are willing to buy a durable composter, you should buy one that you can expand at a later date when the need arises. Notice that, there are composters that are single size. So, if you are hoping to expand, then consider the expandable option.

The capacity

You must consider the capacity of the composter with the expandability. The composter will let you know how many worms they will house. With that, you can calculate to see if it suits your need. A pound of worms will break a half-pound of waste in a day.

The pound worms should guide you into knowing the number of worms that can work on your waste. All these is based on the amount of waste your household produces. With this, you can choose the right composter.

How to Start A Worm Composter

When you decide to make a composter, you will need a few things to get started.

The container

You need the container where the worm composting process will take place. You can even decide to buy a simple plastic container or get a commercial-style warm composter that we have discussed.

Make the bedding for the composting

For the worms to work, you need to provide the proper environment. Worms need a moist and drained bed to work. If the bedding you make can sustain the fresh air and the necessary level of moisture, you will be okay.

Most people use the shredded wet newspaper and leaves. In other instances, you can use egg carton, dried leaves, chopped up straw, aged manure, and seaweed, among others.

Choose the right worms

This is the most vital component when you want to start a worm compost. So, you can buy the following kinds of worms.

  • Red worms
  • Red wigglers
  • Tiger worms
  • Manure worms
  • Red hybrid
  • Brandlings

They are the best when it comes to the choice for composting. All this is because they are best known to work on organic material. Also, make sure you provide the right temperature, which is 21˚C. That will give high product of casting.

Most people prefer red worms because they multiply quickly.

So, what will you feed them with?

While they will help to form compost, not all the food waste can work for them. Notice that worms are more vegetarians. They won’t eat meat products.

You can use vegetable scraps, fruit peels, crushed eggshells, teabags, coffee grounds. But don’t bother adding meat, butter, fish, chicken, cheese, animal waste, and oil because they won’t eat it.

You should add the food waste over the bedding to form a thin layer then let the worms come to the surface and eat the food waste layer.

The compost harvesting

You should expect the compost to be harvested in three to four months. Within the time the worms will have digested all the waste you put in there. But you should keep checking the bin. When there is a rich black soil-like addition to the beddings, the compost is ready for harvesting.

The casting has more humic acid with more potassium, phosphorus, and nitrogen than the one in your garden soil. This has a great impact to the soil.

Wrapping Up

With that said, notice that whether you wish to set the composter indoors or outdoors, you will find the right bin. However, be ready to fight the soldier flies if you set the bin outdoors over time. They can overpower the worms and even stop the worm multiplication.
