Question 1

Will Bokashi attract vermin to my garden?

Accepted Answer

No, Bokashi is one of the most vermin-proof composting methods as it is completely contained. Once brewed and added to your compost or soil because the waste is acidic during the fermentation process it helps make it unappealing to rats, mice, and other pests. Obviously vermin will eat everything so the main point is to deal with the pests you have but if there is a problem the best option is to use a soil factory. If you’re worried about animals digging in your garden, this method is a game-changer.

Question 2

Can I put anything in my Bokashi bin?

Accepted Answer

Not quite anything, but almost! You can add:

Cooked and uncooked food waste: Vegetables, meat, dairy, bread, rice, pasta, and even eggshells.

Leftovers: Including those greasy scraps that wouldn’t normally go in a traditional compost heap.

Avoid:

Liquids: Oil, milk, or excessive sauces can interfere with fermentation.

Large bones: These take ages to break down.

Non-food items: Stick to kitchen scraps—no paper, plastic, or garden waste.

Wiggly tip: Chop larger items into smaller pieces to help the microbes do their work more efficiently.

Question 3

Does Bokashi smell?

Accepted Answer

No. Bokashi waste smells pleasantly tangy—like pickled vegetables or cider vinegar. This is a sign that fermentation is working. If it does smell rotten or putrid, it’s usually because too much liquid has built up, or the lid hasn’t been sealed tightly enough. Drain the liquid regularly and ensure the bin is airtight for the best results.

Question 4

How long does it take for Bokashi waste to break down?

Accepted Answer

In the bin: It ferments in about 10–14 days, depending on the temperature.

In the soil factory: Once added to soil, it takes 4–6 weeks to transform into rich, crumbly compost, ready to use in your garden.

Burying directly: If you bury it in your garden, it breaks down within about 2-4 weeks, although this can vary based on soil temperature and activity.

Bokashi is faster than traditional composting because the fermentation kickstarts the breakdown process.

Question 5

How does Bokashi-fermented waste improve soil health compared to just burying waste?

Accepted Answer

When you bury raw food waste, it decomposes slowly and unevenly, often creating pockets of anaerobic (oxygen-starved) decay that can attract pests and produce harmful gases like methane.

Decomposes faster: Microbes in the waste immediately go to work, enriching the soil.

Feeds soil life: Beneficial bacteria and fungi thrive on the organic acids and nutrients, improving soil structure and fertility.

Enhances nutrient cycling: Bokashi breaks down nutrients into plant-available forms, so your garden gets an instant boost.

The result? A healthier, more resilient soil ecosystem.

Question 6

What are the benefits of using Bokashi composting over a traditional compost heap?

Accepted Answer

Handles all food waste: Including meat, dairy, and cooked foods—things that traditional heaps can’t manage.

Compact and efficient: Perfect for small spaces or urban gardens.

Vermin-proof: No attraction for rats or pests when used properly.

Quick results: Fermentation speeds up the composting process dramatically.

Nutrient-packed: The finished compost is loaded with beneficial microbes and nutrients for your soil.

Less waste: Bokashi composting drastically reduces what goes into your bin or landfill.

Question 7

Can I skip the soil factory and bury Bokashi waste straight into my garden?

Accepted Answer

Yes, absolutely! Dig a trench at least 6–8 inches deep, add your fermented Bokashi waste, and cover it with soil. The microbes in the Bokashi waste will continue breaking it down underground, enriching the surrounding soil. However, there are a few things to keep in mind:

Timing: Avoid planting directly on top of the buried waste for a few weeks to allow it to decompose fully.

Seasonal challenges: A soil factory can be easier during colder months or when your garden beds are in full use.

Question 8

Can I use the liquid drained from my Bokashi bin?

Accepted Answer

Yes, and it’s really versatile!

As plant food: Dilute it 1:100 with water (that’s one tablespoon per litre) and use it as a fertiliser for houseplants or garden beds. It’s packed with nutrients that plants love.

For drains: Use it neat to clear and deodorise your drains. The beneficial microbes will tackle blockages and smells naturally.

As a pest deterrent: A stronger solution can even help deter pests from your garden.

Remember to drain the liquid every few days to keep the bin working efficiently.

Question 9

What’s the science behind Bokashi composting?

Accepted Answer

Bokashi relies on effective microorganisms (EMs), primarily lactic acid bacteria, yeast, and phototrophic bacteria. These microbes work together to ferment organic matter in an oxygen-free environment, breaking it down into simpler compounds. Fermentation preserves nutrients, reduces pathogens, and produces beneficial by-products like organic acids. Unlike traditional composting, where heat is generated and nutrients can be lost, Bokashi locks in the goodness, creating a nutrient-rich product for your soil.

Question 10

Do I need a lot of space for a soil factory?

Accepted Answer

Not at all! A soil factory can be as compact as you like. A large plastic storage tub with a tight-fitting lid works brilliantly and can be kept in a corner of your garden, greenhouse, or even on a balcony. If you’ve got space for a couple of bins, you can set up a rotation system to keep things running smoothly. It’s perfect for those with limited outdoor space or urban gardeners.
