Unlocking the Benefits of Bokashi for Your Worm Bin

Bokashi Vermiculture is a process that combines Bokashi fermentation and Worm composting. We use Bokashi fermentation to process the fruit and vegetable kitchen waste from two households. The worms rapidly process the Bokashi fermentation product into vermicompost. This process can be done in a short period of time!


You may have heard of Bokashi composting and wondered what the fuss is all about. In this article, we'll explore the benefits of Bokashi for your worm bin/vermicomposting setup, and teach you ways to incorporate the principles into your existing composting routine.

Bokashi is a Japanese term that means "fermentation." In the context of composting, it refers to a process by which organic waste is broken down into a nutrient-rich soil amendment. Bokashi composting is a great way to add nutrients to your garden, and it's especially beneficial for worm bins.

Adding bokashi to your worm bin is easy! Just follow the steps below and you'll be on your way to healthy soil amendments for your garden.

What Is Bokashi and Why Should You Use It?

Bokashi is a Japanese term that translates to "fermented organic matter." It's a type of compost that's made from fermenting organic matter in the presence of anaerobic bacteria. Bokashi is a great way to add nutrients to your worm bin because the anaerobic bacteria breaks down the complex carbohydrates, proteins and lipids in the organic matter to create a nutrient-rich compost.

You can add "bokashi" to your worm bin in two ways: by burying it in the soil or by adding it to the top layer of the bin. If you bury it in the soil, make sure to cover it with a thin layer of earth to keep out the oxygen. If you add it to the top layer of the bin, make sure to mix it in well so that the worms have access to it.

Pros and Cons of Using Bokashi in a Worm Bin

Bokashi has some definite pros and cons when used in a worm bin.

On the plus side, Bokashi helps to speed up the composting process and can help with getting rid of odors. It also introduces beneficial microbes into the compost that help to break down the organic matter. This makes Bokashi a good choice for starting or bulking up a worm bin.

However, there are some potential downsides to using Bokashi in a worm bin. For one thing, the high acidity of the Bokashi can kill worms if too much is used. It's also important to note that Bokashi is not a complete food source for worms—you'll still need to provide them with some other organic matter to eat.

Preparing Your Worm Bin for Bokashi Composting

Now that you have your worms and your worm bin, it's time to start adding Bokashi to the mix. In order for Bokashi to work its magic, you'll need to add it in a specific way.

Bokashi is a Japanese word that means "fermented organic matter." It's a type of compost that can be used to improve the soil in your garden. Bokashi is made by fermenting fruits, vegetables and grains in an airtight container.

To add Bokashi to your worm bin, first bury a handful of Bokashi in a corner of the bin. Then, add a layer of bedding and worms on top of the Bokashi. Repeat this process until the bin is full. Make sure to bury the Bokashi well, so the worms can't get to it.

Step-by-Step Guide for Adding Bokashi to Your Worm Bin

Adding bokashi to your wormery is a great way to improve the health of your worms, and there are a few steps you need to take. First, you'll need to obtain some Bokashi Bran—you can purchase it online or from your local gardening store. Once you have your Bran, it's time to get started!

To begin, sprinkle generous amounts of the Bran on top of the bedding in your worm bin—it should be half an inch or so deep, depending on how large the bin is. Next, add some food scraps—a mix of fruit and vegetable scraps works great—and then cover them with another layer of Bokashi Bran. Cover the top of the bin with a cloth cover or lid, and wait for two days before adding more food.

On the third day, fill up any sections that don't have enough food in them. Take care not to overload one section too much as this can cause problems later on. Add an extra 1/4 inch layer of Bokashi Bran each day until all sections are filled up. Make sure to occasionally give your bin a stir to aerate it and check for dampness; if necessary add more bedding as needed.

With this step-by-step guide you'll soon be able to get bokashi into your soon-to-be vermicompost factory and start reaping all its benefits!

Best Practices for Managing a Worm Bin With Bokashi

Now that you understand the basics of bokashi for your worm bin, let's talk about proper practices for managing your bin with bokashi.

To begin, it's important to remember that worms prefer a pH level between 6 and 8. This means you'll want to measure pH levels regularly, as adding too much bokashi bran can mean an overly acidic environment. Plus, you'll want to make sure there is enough moisture in the bin—worms need at least 75-90% humidity for their composting to work well.

You should also keep an eye on the right mix of carbon and nitrogen—worms will feed on both; however, they are mainly attracted to nitrogen because it is a key component of their food. Too much nitrogen can cause worms to quickly consume the food and leave behind excess nitrogen in the soil, which can have adverse effects on vegetable growth.

Finally, if the material smells bad or is too wet or dry, rest assured; removing some material (we recommend no more than 1-2 inches) or adjusting moisture levels usually solves this issue quickly. Just don't forget to add Bokashi Bran if taking out more material!

Troubleshooting Tips When Using Bokashi in a Worm Bin

No matter how much you prepare, it’s possible that your worms won’t take to the bokashi right away, or at all. That being said, here are a few troubleshooting tips should you find yourself in this situation.

Firstly, if your worms are not interested in the bokashi, consider adding some organic material to the mix. This will help make it more palatable for them. However, it is important to make sure that what you’re adding is pre-composted or else it could have an adverse effect on your bin.

You also need to be mindful of how much bokashi you’re adding: it should always be no more than 25% of the entire compost mix in order for your worms to properly digest it and prevent any sort of over fermentation. If there is an odor coming from your bin, then this could be a sign that you’re adding too much bokashi too quickly.

Finally, keep in mind that while bokashi can be incredibly beneficial to your compost pile and worms, it needs time to properly integrate into the ecosystem of your bin and needs active management before and after its introduction.


Bokashi is a great way to give your worms the nutrients they need to thrive, and it's easy to do! Just add a layer of bokashi to your worm bin, and your worms will do the rest.

Not only will your worms be happier and healthier, but you'll also be able to compost more of your kitchen scraps. Bokashi is a great way to reduce your food waste, and it's good for the environment.
