Appropriate Tech is the New High Tech

On his blog, the Archdruid Report, John Michael Greer has a provocative essay, “Seeking the Gaianomicon” that includes a link to a collection of 1970s/80s era appropriate technology handouts. The 190 page pdf Greer mentions (accessible at http://www.culturalconservers.org/apptech.php) includes information and how-to advice on insulation, storm windows, solar water heaters, super-insulated homes, simple photovoltaic systems and more.Greer is asking that readers spread the word about this resource. He also suggests starting your own library of appropriate technology classics. Both are great ideas.

Our blog, in fact, was largely inspired by just this type of literature in the form of a book by Sim Van der Ryn The Integral Urban House: Self Reliant Living in the City as well as other books such as Lloyd Kahn’s Shelter. Keeping with Greer’s idea of building an appropriate tech library we’ll dig up some more books and links. In the meantime, I can think of one other free downloadable book, David Bainbridge’s The Integral Passive Solar Water Heater Book, that you can access for free via the Build It Solar website at: http://www.builditsolar.com/Projects/WaterHeating/ISPWH/ispwh.htm

If any of you know of more appropriate tech books, blogs or resources worth looking at, please leave a comment.

And thanks to the Homegrown Evolution reader who noticed our oddball interest in both appropriate tech and western esotericism and turned us on to the Archdruid.

Urban Permaculture Survey/Interview

Attention urban/suburban permaculturists. I’m writing an article for Urban Farm Magazine on “urban permaculture” and I need your help. I’ve created a survey/interview for the article: click here to take the Urban Farm permaculture article survey. Please forward this link/survey to all your permaculture friends–send it out far and wide–work that Facebook! If you’re critical of permaculture you are also welcome to take the survey. Thanks for your help!

Staking Tomatoes with Concrete Reinforcing Mesh

For years we’ve been using concrete reinforcing mesh to stake our tomatoes. It’s a 6-inch square grid of wire and is used to reinforce concrete slabs. I buy it in 3 1/2-feet by 7-feet sections at my local home improvement center. To make a tomato cage with it you find a flat stretch of patio or driveway and bend the wire into a tube. I overlap it a bit and tie it together with wire.

This year, thanks to a tip from Craig Ruggless, I decided to double the height of the cages using two per plant to make them 7-feet high. As the plant grows, you simply tuck the vines into the cage, with no pruning necessary. But you do have to stay on top of the tucking, otherwise you risk breaking off stems. Since a 7-foot cage can be very top heavy I staked them deep into the ground with some rebar I had laying around. Long wooden stakes would work just as well. You could also choose to grow shorter tomato varieties. The San Marzano tomatoes in the middle of the picture above are half the height of the other two and way more productive.

Another staking option is to buy Texas Tomato Cages for $99 for six 24-inch by 6-foot cages. The advantage with the Texas cages is that they fold flat when not in use. The disadvantage is the price. If you buy your concrete reinforcing mesh in bulk, on long rolls, the price would be significantly less than the Texas Cages and I think reinforcing wire is just as attractive if rolled carefully.

I would avoid the tiny, flimsy conical cages I’ve seen for sale at most nurseries as almost every tomato plant will easily outgrow them and stems will break as they spill over the top.

For a roundup tomato staking techniques see the Santa Clara County Master Gardeners website.
