Composting is one of the best ways to recycle organic waste and create nutrient-rich soil for gardening. However, traditional composting can be slow, labor-intensive, and sometimes limited in what materials can be composted. Bokashi composting offers an innovative solution by using anaerobic fermentation to break down food scraps quickly, including items like dairy and meat, which are typically not recommended in traditional composting systems.
Bokashi composting is gaining popularity among eco-conscious gardeners due to its speed, efficiency, and ability to handle a wider range of organic materials. Unlike aerobic composting, which relies on oxygen and decomposition, Bokashi composting involves beneficial microbes that ferment waste, preventing odor and accelerating the composting process. This method results in a pre-compost product that enriches the soil when buried or added to a compost pile.
This article will cover everything you need to know about Bokashi composting, including its benefits, step-by-step process, and tips for success.
What is Bokashi Composting?
Bokashi composting is an anaerobic fermentation process that uses a specialized Bokashi bran, which contains a mixture of beneficial microorganisms such as lactic acid bacteria, yeasts, and phototrophic bacteria. These microbes break down organic waste without producing foul odors, unlike traditional composting, which requires oxygen and can emit strong smells if not properly managed.
The process takes place in a sealed, airtight Bokashi bucket with a drainage spout for collecting liquid byproducts known as Bokashi tea, a powerful natural fertilizer. Within two weeks, the food waste undergoes fermentation, making it easy to integrate into garden soil for further decomposition and nutrient release.
Benefits of Bokashi Composting
1. Faster Than Traditional Composting
Unlike aerobic composting, which can take months, Bokashi composting ferments organic waste in just 14 days, significantly reducing the time needed to process food scraps.
2. Handles More Types of Food Waste
Bokashi composting allows for the inclusion of materials that traditional composting systems avoid, such as:
- Meat and fish scraps
- Dairy products
- Cooked foods
- Small bones
3. Minimal Odor and No Pests
Since the process is anaerobic and occurs in an airtight container, it eliminates odors and prevents pests such as rodents and flies from being attracted to the compost.
4. Produces Bokashi Tea (Liquid Fertilizer)
The fermentation process generates Bokashi tea, a liquid rich in nutrients and beneficial microbes that can be diluted and used as a fertilizer for plants or as a natural drain cleaner.
5. Enhances Soil Health
When the fermented waste is buried, it rapidly enriches the soil, boosting microbial activity and improving soil structure and fertility.
Step-by-Step Guide to Bokashi Composting
Step 1: Gather Your Materials
To start Bokashi composting, you’ll need:
- A Bokashi bin (an airtight bucket with a drainage spout)
- Bokashi bran (a mix of beneficial microbes and bran material)
- Food waste (including fruit, vegetables, meat, dairy, and cooked foods)
Step 2: Add Food Scraps to the Bin
- Chop food scraps into smaller pieces to speed up fermentation.
- Place a layer of food waste inside the Bokashi bin.
Step 3: Sprinkle Bokashi Bran
- Add a handful of Bokashi bran over the food waste.
- Ensure the bran fully covers the scraps to activate fermentation.
Step 4: Press Down and Seal the Lid
- Use a plate or tamper to press down the waste and remove air pockets.
- Seal the bin tightly to maintain anaerobic conditions.
Step 5: Drain Bokashi Tea Regularly
- Every 2–3 days, drain the liquid from the spout at the bottom of the bin.
- Dilute the Bokashi tea (1:100) with water and use it to fertilize plants.
Step 6: Repeat Until the Bin is Full
- Continue layering food waste and Bokashi bran until the bin is full.
- Once full, let it ferment for 14 days, keeping the lid tightly closed.
Step 7: Bury or Compost the Fermented Waste
- After fermentation, the waste will have a pickled smell and soft texture.
- Dig a hole in your garden soil and bury the waste 6–8 inches deep.
- Alternatively, mix it into an active compost pile to speed up decomposition.
How to Use Bokashi Compost in Your Garden
Once the Bokashi waste is buried, it continues breaking down in the soil within 2 to 4 weeks. The microorganisms in the fermented waste enrich the soil, creating a nutrient-dense environment for plants.
Best Uses for Bokashi Compost:
✅ Bury directly in garden beds to improve soil fertility ✅ Add to raised beds for enhanced microbial activity ✅ Mix with traditional compost to accelerate decomposition ✅ Use as a soil amendment for potted plants
Common Mistakes to Avoid
🚫 Not Draining the Bokashi Tea – Excess liquid can cause anaerobic rot instead of fermentation. Drain it every few days.
🚫 Exposing the Fermented Waste to Air – When transferring the waste, bury it immediately to prevent unwanted odors and decomposition issues.
🚫 Forgetting to Seal the Lid Properly – If air gets inside, the fermentation process may be disrupted, leading to spoilage.
🚫 Using Moldy Bokashi Bran – Ensure your Bokashi bran is fresh and free from harmful mold. Proper storage is essential.
FAQs About Bokashi Composting
1. Does Bokashi composting smell bad?
No, Bokashi composting has a mild, pickled smell due to fermentation. It does not produce the strong, rotting odor associated with traditional composting.
2. Can I compost citrus and onions in Bokashi?
Yes! Unlike traditional composting, Bokashi can handle citrus, onions, and other acidic food scraps without problems.
3. How long does it take for Bokashi compost to break down in soil?
After burying, it typically decomposes within 2–4 weeks, depending on soil conditions and microbial activity.
4. Can I use Bokashi in potted plants?
Yes, but allow it to fully break down in the soil before mixing it into potting soil.
Final Thoughts: Why You Should Try Bokashi Composting
Bokashi composting is a fast, efficient, and eco-friendly way to handle kitchen waste while enhancing soil health and plant growth. Whether you have a small urban garden or a large backyard, this method can transform the way you compost.
By reducing waste, preventing odor, and producing rich organic matter for your garden, Bokashi composting is a must-try technique for sustainable gardeners.
