Tatami Mat Mulch

While some weeds are my favorite garden volunteers, there are times when I don't appreciate them. Last summer, for example, when we returned from Hokkaido I was greeted by a garden nearly hidden in tall weeds. Somehow despite the heat and drought they managed to thrive. Sheltered in part by my rambling squash vines, I'm sure, they resulted in more than a few hours in the hot sun removing them. And more than a little embarrassment, as the farmers keep an incredibly tidy farm and my garden is definitely...different.

An alternative solution to more black plastic mulch, hand-weeding, and periodic chemical spraying presented itself one day when I chose an alternate route for running errands. A number of farms dot our area of Tokyo, and those lying to our east are still relatively unknown to me. Exploring almost always results in finding a new vegetable stand or a lovely farm tucked just behind the main roads or adjacent to an apartment building. It was while toodling along on the north side of the tracks that I spotted a small field using old tatami mats as mulch. "Brilliant!" I thought, and promptly parked my bike to snap photos.

Tatami mats are a traditional floor covering in Japanese homes, although these days usually only in one room. (Here's a great article on attempts to revive the industry in Japan.) Woven from straw and edged with strips of decorative cloth, the mats are pleasant for sitting, standing. or sleeping. And as they fade from their initial green to gold, they infuse a room with warmth and light. Changed out yearly, old tatami mats pile up, and what better way to recycle them than as a water permeable mulch that can be composted?

Yesterday my gardening friend and I picked up the mats from our local tatami master. He knew immediately what we were after and why, and took us back to his workshop. There alongside the long table where he weaves the mats were two bundles ready to go. Made up of about six individual mats each they were surprisingly light. My friend carried one and I balanced the other on my bicycle and we were off.

My garden measures roughly 18 meters long by eight meters wide, so I need a fair number of tatami. By Tokyo standards it's a massive space, and so the tatami master didn't really believe me when I told him how much I wanted. As it is, the two rolls of mats laid end to end (no overlap) cover two of the four paths running the length of the garden. Some trimming will have to occur as the paths are a bit narrower than the tatami, but I'm excited to see how this latest experiment works out.

Got a favorite garden recycling story? I'm all ears!

I loved the tatami mats in our little apartment in Urayasu- they did bring warmth to the room- a certain 'cosy' feeling.

Will look forward to seeing how your recycling of the mats goes...keep us updated. My only example of recycling in my garden is coffee grinds from the nearby starbucks- I think I'm the only one who goes there and picks up their massive packs of coffee grinds which is offered "for your gardening needs"- FREE (oh I like that word) :)...it has done well for my little flower bed.
Coffee grinds are great, Anjuli. They're a fantastic source of nitrogen, and mixed with any eggshells you use in your home (buried a wee bit)you'll be giving your plants a nice little long-term snack.

We love our tatami room, too. By day it's our office/den/yoga space, and at night it's our bedroom. The tatami form the cushy floor we sleep on.

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

Kamakura Farmers Market: Giant Buddhas and Good Vegetables

Kamakura Farmers Market entrance A little more than an hour train ride south of Tokyo sits Kamakura. Like Kyoto and Nara, Kamakura is a former capital full to the brim with temples, shrines, and a bounty of historical sites lining its winding streets. Nestled in a cozy bay with beaches and a giant Buddha tucked amongst the rest, it's a city that invites multiple visits if not at least one. And those seeking a farmers market well-stocked with traditional vegetables, skilled growers ready to share recipes and chat about their wares, along with some nifty prepared foods to rejuvenate themselves after so many temples surely won't be disappointed, either. Kamakura Farmers Market - right side full of signs Started nearly twenty years ago, the Kamakura Farmers Market or Kamakurasui Nyogyou Rensokubaijo, runs seven days a week nearly year-round. A ten-minute walk from the station, the market is located in what at first glance looks like nothing so much as a run-down w

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
