Reprise: Getting Started with Vermicomposting

This article first appeared over at, a lovely little website where I wrote a regular column for a handful of years. It is the second part in a series on vermicomposting (composting with worms) covering how to get started and using the lovely materials provided.  - JB

Budding vermicomposters can make their own bins or order a kit from a variety of sources. Kits usually include a container, worms, and plenty of instruction and support needed to get comfortable with your new little helpers.

Bins can be made from plastic storage containers where holes have been drilled in the bottom or constructed from scrap wood for a custom-made fit and look. The possibilities are only limited by your imagination, the materials at hand, and the space available. 

Do your research.
James Kemp, importer of Australia's Can-O-Worms composter, says a little reading goes a long way when it comes to vermicomposting. They are, he says, living creatures.

“It's important to read the manual, and there is plenty of advice and info on the internet,” he said. “The failure rate is for beginners is fairly high, though” said Kemp. “People don't follow the instructions or they feed them the wrong food."

Worms Eat My Garbage by Mary Appelhof (Flower Press, 2003) is a charming guide to vermicomposting offering tips on building your own to long-term management and problem-solving. 

Websites like Kemp’s (Japanese only) and Can-O-Worms offer plenty of useful advice and contact information if a vermicomposter runs into trouble. Other sites such as UNL and OneMore can fill readers in on the joys of vermicomposting.

A Few Things to Keep in Mind
Vermicomposting is relatively easy, but there are a few things to avoid and some best practices, too, to keep worms healthy, happy, and composting.

  • Choose the bins location carefully. Worms don’t like extremeness in temperature, so find a slightly sheltered place on the balcony or in a garage for the bin. “You need to be aware of your environment. Worms don't like to get too hot, so if your worm farm is in direct sunlight all day during summer, then they will almost certainly die” warned Kemp.

  • Don't use insecticides or sprays around your worm bin. Worms are quite sensitive to chemicals, even those commonly used for cockroaches or dani. If you must use these items, then remove the worms and wait until returning them to the environment.

  • Don't use garden soil as bedding for the worms. It may seem logical, but garden soil is an unpredictable medium for the worms. 

  • Don't be afraid of visitors. After you've had your worm bin established, you may notice other creatures besides the redworms, especially if you keep your bin outdoors. Most of these are beneficial because they help breakdown the materials. These helpful creatures include springtails, sowbugs, pill bugs, and millipedes. 

Remember, vermicomposting is a great way to reduce household waste and turn it into something your plants will love. Have fun!

Finding Heirloom Seeds in Japan

Drying pods of heirloom Hutterite Soup Beans. Since moving to Japan eight years ago, one of my greatest challenges as a farmer-gardener has been to find heirloom or open-pollinated seeds. The majority of seeds available are not GMO (genetically modified organisms) as Japan, at this point, doesn't accept this material. Most seeds, though, are nearly all F1 varieties. Heirloom and F1 Varieties In plant breeding, F1 is the name given to the first generation of a cross between two true breeding parents. For example, if I decide to cross an Amish Paste Tomato with another heirloom variety tomato such as Emmy, in hopes of getting a gold paste tomato, the resulting generation of fruit is F1. In order to get that tomato of my culinary dreams, I'll need to choose members of that first generation that are headed in a direction I like - early ripening, medium-sized fruit, good taste - and save their seeds. I'll plant them and repeat the process again and again over time unti

Satoimo: One of Japan's Favorite Slimy Things

Satoimo in all their hairy glory. This post first appeared in slightly different form on Garden to Table as part of the 2012  Blogathon . The website has since moved on to the ether, but the post is still a good one. After all, people here are still eating satoimo on a daily basis, and many others are just seeing these little potato-like objects for the first time. Enjoy! Satoimo is one of Japan's odder vegetables. Under it's rough, slightly furry skin is white flesh that is a little bit slimy even raw, and with a gentle nutty flavor.* Baked, grilled, steamed with dashi, or deep-fried satoimo stands well on its own or paired up with other vegetables and meats in a wide variety of soups and stews . (The leaves are also edible.) Satoimo stores well, and like any root crop worth the effort, stocks are just running low on this household favorite as the farmers in my area of Tokyo get ready to put a new crop in the ground in May. I cannot say I was a fan of this l

Goma Ai Shingiku - Sesame and Chrysanthemum Greens

Last week I had the pleasure of helping some friends work in their parents garden not too far away. Tucked behind the house, the garden sits on a former house lot. When it came up for sale about five years ago, my friend's father jumped at the chance. Open land in Tokyo can be hard to find and expensive, but for a retired professional looking for a little spot to till in the city it was an opportunity to good to pass up. Now, it is a garden to envy. As we came through the gate rose, lily, and peony blooms greeted us with great shouts of color while rows of vegetables stood tidily at attention on the sunny center stage. Small fruit trees along with one of the biggest sansho trees I've seen yet stood quietly here and there. Near waist-high sweet corn, bushy young potato plants, cherry tomatoes, eggplants, and beans were preparing their summer fruits, while a handful of still quite luscious looking winter vegetables like komatsuna, mizuna, and kabu held one last ro
