Where is Bokashi hot?

Google has a trend meter where you can type in a word and see where the hotspots are in the world.

So of course I typed in “bokashi” to see what would turn up. Bokashi is a Japanese word but it’s used widely around the globe as the name for, well, Bokashi. As in household fermenting of kitchen waste.

It turns out that NZ and Australia are the hot spots. Which doesn’t surprise me having grown up in NZ and lived in Australia for many years. Not that people are any greener there than anywhere else, it’s just that there have been a few people who’ve been passionate about getting Bokashi started. In NZ it all began some 10 years ago and is now a part of daily life for many people I know. In Australia it started to gain momentum a few years later, but is again rolling out into the mainstream.

I know for a fact there are millions of users of Bokashi in cities and villages in Asia, but they are not necessarily showing up on Google’s trend-o-meter. Indonesia tops the chart by a huge margin, so I wonder if Bokashi doesn’t have an extra meaning in Bahasa Indonesian or one of their many other languages.

So: — top of the Bokashi pops are (cities):

1. Auckland, New Zealand
2. Jakarta, Indonesia
3. North Shore, New Zealand
4. Adelaide, Australia
5. Melbourne, Australia
6. Perth, Australia
7. Sydney, Australia
8. Brisbane, Australia
9. London, United Kingdom
10. Manchester, United Kingdom

The countries topping the list for news references to Bokashi were the following:

Indonesia, New Zealand, Australia, Malaysia, United Kingdom, Columbia, Switzerland, Austria, Brazil, Netherlands.

We haven’t got Sweden onto the map yet but we will!!

Bokashi 1-2-3

Jenny Harlen

The thing with Bokashi is that it’s dead easy. The whole concept seems really strange and different at first but when you start doing it you can’t help thinking what’s the big deal. Because there is none, big deal that is. Basically you just toss your kitchen waste in a different bin to what you used to and at the end of the day take care of it yourself instead of waiting for someone else to do it for you.

So: the Bokashi 1-2-3.

1. Put all your food scraps from the day in your Bokashi bin — meat, fish, pasta, coffee, veggies.

2. Sprinkle over a handful of Bokashi bran — the “good” microbes start working on your food waste.

3. Keep on filling your bucket until it’s full then leave it to ferment for a couple of weeks while you fill the other bucket.

4. Drain off the Bokashi liquid regularly — it’s a fantastic organic fertilser for your plants.

5. Use your Bokashi compost in the garden! Dig it down into your veggie patch or garden beds, add it into to your traditional compost, or mix with soil in outdoor flower planters or tomato pots.

6. Enjoy your healthy plants and the knowledge you’re doing a great thing for the environment!

What’s your Bokashi bin called?

I was explaining Bokashi to a woman I met the other day with my usual enthusiasm. (Being a bit of a compost nerd at heart and all that.)

She was really interested, got it immediately and you could see the light bulb go on as she went through the mental steps of how this would work at home. Then came the giggle.

“Well I think I’ll have to call mine Allan. Reminds me of my Dad.”

So it turns out Dad always ate up everyone’s leftovers. Quite proud he was of it too. Pity help the kids if they ate up everything themselves…

Back in the old days everyone had a household pig. I’ve often thought of that as I pull off the lid of my bin and shovel in the day’s scraps. A pig would have been nice but a Bokashi bin is better, I would never have been able to serve the guy up for Christmas dinner. Better we feed the garden instead.

No, our Bokashi bin at home is called Junior. Named by our daughter, who I must say is very glad to have him around. Junior loves leftover spaghetti and meatballs, and is particularly fond of vegetables and other icky-sticky suspicious items that she would really rather not face just this day.

“I know, I’ll give it to Junior!” I fall for it every time…

So what’s the Bokashi bin in your family called?

Mid-winter Bokashi storage


We live in Sweden, if you draw a line between Oslo and Stockholm we’re half-way along that. Which is not quite the Arctic Circle (fortunately), but right at the moment as I look out the window at a frozen landscape with foraging deer the temperature is somewhere around -10 degrees Celsius.

Perfect skating weather, but a lousy time for gardening.

So what do we do with all our fermented Bokashi at this time of year? The ground is pretty much frozen solid from November through March, so digging it down is out of the question. We do have an insulated compost so a few Bokashi buckets go into that in the course of a winter, it helps keep some semblance of activity going in there and Bokashi is a good addition to any compost — more on that later.

But most of our fermented Bokashi we save over the winter. Come spring we need tons of the stuff and we just can’t produce it fast enough when the time finally comes.

A newly-filled Bokashi bin needs to ferment indoors for a couple of weeks or so before it’s ready to dig down or put into winter storage. When we need the bucket again I simply tip the contents into a big barrel in the wood shed. First I make sure it’s really well drained, then I add a few newspapers into the barrel to soak up any excess liquid. It’s the liquid will get you every time — if it builds up your Bokashi compost will rot. Same with the air — your barrel has to be airtight or things will start to go wrong.

So add a couple of thick newspapers top and bottom and make sure the lid’s on tight.

Temperature on the other hand is not so critical. Bokashi has to be kept warm during the fermenting process, but it can then be stored in whatever storage facility works best for you. In our case the wood shed, for others it may be a laundry or a garage. The microbes go into hibernation at temperatures below +6 degrees C or so and even if they have been frozen for a while they will go back into action again when they warm up again. While they can cope with the cold if they have to, what they don’t like so much is a lot of temperature variation, so try to pick a protected place with a temperature that’s as stable as possible. Not outdoors in the sun and wind in other words.


Come spring it’s a party. We use 35 liter bins with tight lids (each takes the contents of a couple of kitchen Bokashi buckets), bigger barrels also work but take far too long to thaw out in the spring.

Some of our Bokashi gold heads straight for the glasshouse, I mix it with cheap soil directly in the big pots we grow tomatoes in. After a few weeks the soil is fantastic, the tomatoes love it and its better than anything you can get in the shop.

Another few bins head for the veggie patch, I dig them straight down into the soil there. Then sit back and wait for the worms to come! It gives the seedlings a great start and helps replace some of the soil that went into last years harvest. The plants always seem to be stronger and healthier, and you can tell just by feeling a fistful of soil that they’re going to thrive in it.

Then — and this is a strictly rationed process!  — another bin or two goes into the outdoor flower pots. Out with all the old soil and in with a layer of shop-soil, a layer of Bokashi kompost, and another layer of soil. The more the Bokashi is mixed in with the soil the faster it will turn into soil so it’s good to stir it up a bit. The important thing is that the roots of your plants don’t grow into the Bokashi until it has turned to soil, it’s too acidic at the start. But often the plants are tiny and won’t reach so far down into the pot for some weeks anyhow so it all sorts itself out.

And finally, IF there’s any left over, I give the compost bin a dose. Helps it get going again after the winter, and the whole composting process is much faster and healthier for the environment if it includes Bokashi than if it doesn’t.

So in these dark days of mid-winter you can see it’s a pleasure to stack up as many Bokashi barrels as possible in wait for the spring. The more Bokashi I have the sooner spring will arrive. Or is that just wishful thinking?

Bokashi tips: Daily life on the kitchen bench


Modern still life: bananas and tomato with fresh herbs. Oh, and the Bokashi bench-top thingy.

What you’re really doing when you bring a Bokashi bucket into your kitchen is swapping one rubbish bin with another. ALL your food waste will go into the Bokashi bin and by the time you recycle everything else (you know, glass, plastic, metal, paper, all those damn batteries and light bulbs…) there’s more or less nothing else. So you can pop in a micro bin, a couple of litres or so, under your bench alongside the Bokashi bin and toss the old rubbish bin. Well hang on, we don’t just toss things any more, right? So recycle it into some sort of container for uh, recycling paper or something.

Anyhow, unlike your old toss-it-all-in rubbish bin that was always ready to receive, your shiny new Bokashi bin doesn’t like to be opened more than once or twice a day (microbes really HATE air). So the trick is to collect your scraps somewhere handy until it’s the daily Bokashi Hour. (Well, I’m joking, it doesn’t need to be the same hour every day.)

We use a flowerpot for this, the kind that doesn’t have a hole. It’s the white shiny thing in the picture. And we’ve plopped a standard terracotta pot saucer on top which keeps it vaguely airtight and keeps any visiting fruit flies out. This works perfectly, and actually I wish I’d done this years ago, even with the old rubbish bin system.

It’s much easier to throw an apple core or tea bag into the benchtop caddy than to open the cupboard door under the bench while trying not to get the cupboard door knob too icky and sticky while you’re at it.  A lot of bending and scraping during the course of an average day that, when you stop and think about it, really isn’t necessary. If this was the industry world we could do a productivity study on it and probably find out there’s time and money to save on having a mini-bin at hand for all the small stuff. Especially handy when you’re doing the vegies for dinner to be able to just scrape everything direct into the little Bokashi bin.

And let’s face it, what we throw more than anything during the course of an average day is bits of food — apple cores, potato peelings, a bit of smelly sausage from the fridge, leftover lunch sandwiches… You’d be surprised how it mounts up during the day and we always have one or two full pots that are transferred to the Bokashi bin during the day.

Which is a quick and easy job in itself — just lift off the lid of the Bokashi bin and toss in the contents of your benchtop caddy. You can give it all a bit of a push down with the pot while you’re at it, it’s not necessary to fuss and bother too much over chopping up your food scraps but it is worth compacting the contents of the bin a bit while you’re there anyway. Sprinkle over a handful of Bokashi bran (we store ours in a standard kitchen sprinkler to make it easy) and put on the lid tightly. That’s it.

Mission accomplished. Bokashi hour is fixed and it took all of, what, 60 seconds?

Getting going with Bokashi


So put up your hand if you’re an expert at resisting changes. (Hand going quietly up here…)

I like to think of myself as being open, curious, willing to try new things. In actual fact I’m probably quite cynical, jaded and treat a lot of new things with a healthy measure of suspicion. Until proved otherwise.

Bokashi is one of those things that rung a few hocus-pocus warning bells for me when I first came across it. Forget it. There’s nothing new age or even vaguely hocus pocus about Bokashi. In actual fact it’s as old as the earth and belongs under one category only: good old-fashioned, down-to-earth common sense. The sort of thing farmers have known for hundreds of years but we, in our modern wisdom, have lost sight of.

Bokashi is fermented organic material, a lovely Japanese word that works in all languages and will one day be an unquestioned addition to ours. These days the fermentation is done using Effective Microorganisms (EM), a mix of very natural, age-old “good” bacteria that do the work for us in this process. No hocus pocus there, but a lot more to say in future blogs.

There are two things “Bokashi” and that’s a bit confusing. First, you have Bokashi bran. That’s normal bran — organic of course — that is inoculated with Effective Microorganisms. Fermented quite simply, just like a lot of stuff you’d find in your kitchen, pickles, yoghurt, wine and the like. Then second, you have Bokashi compost, and that’s what you get when you add Bokashi bran to your food waste and leave it to ferment in an airtight bucket.

There’s nothing magic about the bucket, apart from the fact that using a proper Bokashi bucket takes some of the trial and error out of the process. Two things Bokashi microbes hate are being wet and having too much air around them. Which is why the bucket is air-tight and must be drained regularly.

What happens in the bucket then? A lot actually, far more than you’d ever think when you take a look inside and see that, well, nothing much seems to have changed. Every handful of Bokashi bran you throw in has billions of microbes living in it. They go to work on your food waste and eat, breed and generally live a good life. The breeding is no small business, microbes reproduce every 20 minutes and sooneä than you know there’s a hell of a colony in your bucket.

So what are they doing there other than having a good time? The process is symbiotic, that means it’s a give and take thing where all parts win. (Pathogenic bacteria on the other hand, the ones we definitely don’t want in our lives, are just take-takers.)

While they’re eating and breeding, the microbes are breaking down the food waste into another structure. And this is what makes them so valuable. They take the food and sort of split it up into its component parts — proteins, which in turn consist of amino acids and other stuff. Why is this such a big deal? Plants can’t eat our food. But they can eat the amino acids and stuff. So what the microbes are doing is the equivalent of preparing a buffet of goodies for the  plants and soil.

When you dig the content of your Bokashi bucket into  the soil it quickly “disappears”. Obviously it doesn’t disappear at all, it is converted to soil. Rich, nutrient-loaded soil that is like a 5-star buffet for your plants.

It does other great things when you add it to your compost, but that’s a story for another day. As is the story about why Bokashi works as a miniature carbon-sink in your yard, something great you can do for the environment without (hardly) lifting a finger.

Bokashi in a brave new world

First time I heard about Bokashi I wondered what the hell it was. And it made me very curious! Soon I was searching websites up and down for information and my curiousity only increased. This was definitely something we had to test. And assuming it worked (which of course it did, brilliantly), something that had to spread far and wide.

We’ve been composting as long as I can remember. Not especially well, just average drag-and-drop composting where everything ends up in a big heap and some years later you muck around in it and see what you’ve got. I always saw it as more of a storage place for stuff that should go back to nature somehow than for what it really is: a small scale soil factory that gives you everything you need to get your garden growing well.

Bokashi is far more than just a new-fangled form of composting however. And that’s what we’d like to take up here in this blog. Not only what is is, but how it works, why it works, what happens in your soil when Bokashi gets involved, and how to make all things Bokashi run as smoothly as possible.

We have lots of ideas and good information to share! And look forward to sharing it all.

This blog is something we do just to help spread the Bokashi word as far and wide as possible. In Sweden, where we live (even though I’m from New Zealand orginally), we run the EM Bokashi webshop. You can visit it on www.bokashi.se, soon there’ll be an English version but just now it’s only in Swedish.

Please feel free to get in touch if there’s anything you’d like us to take up or would like to know more about. Look forward to hearing from you!
