Benefits Of Worm Composting

Why Use a Worm Composter? Here are a Few Reasons!

Worm composting is faster and more efficient than turning your waste into compost. In the simplest sense, it means that the worms eat your kitchen scraps and turn them into nutritious compost for your garden.

It’s glorified worm poop!

Once the worm colony gets all settled in, you can feed them your household kitchen waste, and they’ll give you fertilizer for your garden in return. You can feed them fruits, bread, coffee grounds, pasta, eggshells, tea bags, cardboard, and even paper.

Now, isn’t this a great way to get rid of your kitchen scraps?

So, What Are the Advantages of Worm Composting?

One of the best things about Vermicomposters is that they come relatively cheap and easy to maintain.

  • Waste Reduction: You’ll be able to significantly reduce your carbon footprint by having a worm composter since you’ll be turning your kitchen scraps into fertile compost!
  • Saying Goodbye to the Stench: Don’t you hate the smell of trash? You can kiss the stench goodbye by putting compostable waste into the compost–you won’t have to worry about missing another garbage day!
  • No pests in the house: When you get rid of your kitchen trash every day, you don’t have to worry about cockroaches or mice getting into your house. No kitchen scraps equal no pests.

Composting and Your Garden

Do you wish to cut down on fertilizer costs?

Everyone wants a beautiful and blooming garden. But fertilizer doesn’t come cheap! You can reduce your costs significantly by installing a worm composter in your garden.

Now, let’s look at some important things you need to know…

Here are Some Must-Haves in a Worm Composter

In this section of the article, we will go over some of the things you need to consider when getting a worm composter.

Take a look.  

Good Drainage

Fruits and vegetables produce a liquid that most people refer to as “worm tea,” also known as leachate. Your worms may not be able to withstand the extra moisture and might even drown due to excess moisture.

So, it becomes important to have drainage material in place, such as a spigot, to make sure everything works smoothly.

Space inside the composter

Composting space is another thing you need to consider when looking for the best worm composter. When you first get your composter, you might not be producing a lot of waste. However, as your family grows in size, so will the organic waste that you produce.

This means that you might need to invest in another composter down the line. An intelligent choice would be to go for a high-quality composter which you can later expand as your needs do.

Air Circulation

It’s important to make sure that your worms have enough room to breathe, which is why it is necessary to choose a well-ventilated composter. A lack of ventilation can lead to excess moisture in the compost bin, increasing the death rate of worms.    

Shade

Worms stay underground and prefer staying away from sunlight. For best results, you should try to emulate their natural environment as closely as possible.    

It’s a good idea to go for an opaque worm composter to block excessive sunlight. Your worms will thrive in this environment and will go on eating!

Ease Way to Harvest Compost

Why not go for a commercial worm composter if it reduces the amount of work you have to put in to harvest the compost?

It wouldn’t be fun to manually remove your worms from the compost every time you harvest the compost. Not only is it time-consuming, but it is also unenjoyable.

So, it is a good idea to go for a system that keeps your needs in mind and makes it easier for you to have access to your compost.

You won’t have to manually remove the worms, bedding, and food. Think of the amount of time you’ll save over the years!

Weather Protection

By investing in a worm composter, you can ensure that your compost will be protected from outside elements.

If you wish to have an outdoor composter, you’ll need to get one with a sturdy lid to keep the rain out. You’ll also have to consider putting the compost bin in a shady spot to not overheat and cause further complications.

On the other hand, if you plan to have the compost indoors, you’ll have to consider factors like sunlight, water, etc.

Here’s a rule of thumb to go by.

If it is too cold, the worms get sluggish and won’t eat as much–they become lazy, just like us in the winter! However, the worms will try to escape if the temperature is on the warmer end of the spectrum.

So, it becomes important to maintain optimal conditions to get the most out of your compost.

Here are 5 Worm Composter Mistakes You MUST Avoid!

This section of the article will go over the top five beginner mistakes you must avoid when it comes to worm composters.

Take a look.

Not Maintaining the Right Temperature

It’s important to make sure that you regulate the temperature of the compost bin–especially if you live in a climate that receives extreme temperatures. Worms can die when the temperature is too hot or cold.

It’s important to choose the right bin location to cool the worms in the summers and warm during the winters.

Forgetting About the Harvest

Some hobbyists forget about harvesting the black gold while the composting bin keeps filling up with worm castings. So, people usually start by adding more trays to put it off.

However, it is important to take out the time to separate the worms from the worm casting–an activity that should only take between 30 to 60 minutes. You can harvest compost:

  • As needed
  • When the bin starts to get full
  • At the beginning of the growing season

Don’t forget about the black gold you’ve created!

Offering the Wrong Foods

Worms cannot process everything that you put in the composting bin. They’re excellent at processing non-acidic vegetable and fruit scraps, such as:

  • Bread
  • Coffee grounds
  • Grains
  • Pasta
  • Teabags

Processed foods, meat, salty snacks, etc., aren’t the best for your worms.

Overfeeding the Worms

Sometimes, people toss everything they can into the compost bin out of enthusiasm. After all, the idea of worms eating your trash and turning into black gold is an exciting one.

However, in such cases, the worms cannot keep up with this never-ending supply of food.

The result?

The trash starts to decompose, and the bin–along with its surroundings starts to smell terrible!

So, it is best to curb the enthusiasm and only feed the worms what they can process.

The Compost Bedding is Too Dry or Too Wet

Finally, you need to maintain the moisture inside the bin. Filling up the bin with water can drown your worms and kill them. The bin can also start to stink when there’s excessive moisture.

On the other hand, letting the compost bin dry out can dehydrate the worms, and the worms won’t tunnel efficiently.

So, it is crucial to maintain the right amount of moisture for the worms to thrive.

Worm Composting 101: Here are Some Frequently Asked Questions

While researching for this article, we came across several frequently asked questions that we’d like to address in this section of the article.

Let’s take a quick look, shall we?

The worm composter has started to stink! It’s getting really bad! Where did I go wrong?

If your worm composter smells bad, it means that there’s something off that you need to address. In most cases, there may be either too much food in the bin or excessive moisture. If those seem to be in order, you should try chopping up the kitchen waste into smaller pieces to make it easier for the worms to eat.

My worms are trying to escape. What should I do?

There are several reasons why your worms may be trying to escape the compost bin. These include:

The bedding is too acidic: You can crush some eggshells and add them to help balance out the pH.
High temperatures: Worms tend to escape when the temperature gets too high. You should relocate the bin to a cooler area to stop the worms from getting away.
Excessive moisture: Try to drain the excessive moisture to help make the compost bin more habitable for the worms.

Fruit Flies seem to be attracted to the bin. What’s the solution?

Insects and fruit flies get tempted by the food in your compost bin and make their way over to get a taste for themselves. This usually happens when the food is close to the surface. Adding dampened cardboard or newspaper on the top can help keep these insects at bay.
