Tokyo Tomato Planting

The tomatoes are all in at the farm. The first round of them went in about ten days ago - 200 plants of red and yellow cherry tomatoes as well as a red grape sized variety - and the second round went in last weekend. Another 200 plants, the large variety, all snugly settled for the growing season. This time, though, the planting went forward despite heavy winds and a rainy forecast. The first crop to go in one of the three new greenhouses recently built at the farm, these tomatoes are part of a larger experiment happening on this urban farm.

Greenhouses are nothing new to farming, not even this small family farm here on the west side of the city. We have four others - much, much smaller - used for starting seedlings, processing the harvest in cold or inclement weather, or growing a temperature sensitive crop under protection. These three new ones though, mark a new slightly more industrial direction for the farm. About 15 meters tall, these three possess thermostats that automatically open vents and run fans depending on the indoor and outdoor temperatures. A sprinkler system makes watering a piece of cake. Side doors will let pollinators in and netting (yet to be hung) will keep birds out.

Planting indoors, in some ways, proved similar to planting outdoors. We prepared the soil in essentially the same way about a week ahead of planting. We'll still place basil at the base of each plant, and the plants will still be trained, trimmed, and clamped to their climbing poles. The young seedlings, though, were set in the ground with flowers facing to the center of the rows to make for easy blossom trimming and harvesting as the time comes. If no blossom was visible, it became an exercise in pattern recognition. Tomato plants always grow in the same way - one branch facing the planter, two swung out to the side, and one off to the left just below the blossom crux - so it was a simple matter of finding the pattern and setting it in the ground correctly. (I have a strong suspicion that some of my plants will need to be harvested on the opposite side, but we'll cross that bridge when we get to it.)

Growing in such a controlled environment has obvious advantages: fewer worries about sudden changes in temperature that can slow or hasten growth; sudden influxes of water that can cause the tomato skin to split and subsequently make the fruit unsellable; protection from wind damage; and the ability to extend the growing season on either end. (Word has it we're thinking of planting new seedlings in the fall to harvest well into the off season.)

And there are a few disadvantages. It can be difficult to maneuver the rototiller/tractor (a mini-version of the American variety) in there, and it's going to be really freakin' hot in there in the summer. (Since I'm not a tomato, I'm not so excited about that prospect.) The reliance on electricity (especially in light of summer's coming blackouts) feels a bit sketchy, and I do worry about how the pollinators will flit in and out. I also have my concerns about a contained monoculture, just as I did at Ikumi Tomato Farm, but again I'll cross that bridge when I get to it.

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
