Gift Suggestions, from the Other Half

Mrs. Homegrown here: Of course Mr. Homegrown didn’t ask me for input on “our” holiday gift guide. Not that I dispute his choices…but I do have some of my own. These are the 4 most thought provoking books (in this topic area) I’ve read this year: The first two are closely related, as they are about the horticultural practices of Native Americans in California. You might remember me writing about them earlier.  A...

Testing the Lead Testers

d us an email at [email protected] or leave a comment. We’re attempting to reconcile slightly different lead results from three different labs and I’d like to be able to write about soil testing methods. Two of the labs we sent samples off to (UMass and Timberleaf Soil Testing) use inductively coupled plasma mass spectrometry (ICP) to test for lead. Wallace labs uses an extractant, AB-DTPA (ammonium bicarbonate Diethylene Triamine...

CoEvolution Quarterly Online

While hunting down old appropriate technology resources on the Internet, I was delighted to find the winter 1978 issue of CoEvolution Quarterly, put out by the folks behind the Whole Earth Catalog. This issue of CoEvolution profiled Robert Kourik (which CoEvolution spells “Kourick”) who practiced permaculture before Bill Mollison gave it a name: [Kourick] is developing methods of growing edible and ornamental plants together for max...

Low Tech Solar Heating with a Thermosyphon Collector

Yet another great post from the folks at Build It Solar: a simple and low tech solar heating system called a thermosyphon collector mounted in the wall of a garage. It uses the same principle as the solar dehydrator we have on our garage roof–basically it’s just some clear plastic and a heat collector made out of black window screen. If your climate is cold and sunny (think Colorado) this would work nicely. Read the post to see a r...

LA Times Calls Vertical Gardens in a Dry Climate a Bad Idea

Wooly Pockets at Homeboy Industries Writing for the LA Times, Emily Green has penned a skeptical look at wall-based growing, “The Dry Garden: A skeptic’s view of vertical gardens.” I’m in complete agreement with Green and wrote about this silly trend back in July. Says Green of a garden in Culver City that uses the Wooly Pocket vertical system, “The concrete wall behind the bagged-and-hung garden is wet wi...

Avatar: I’m not lovin’ it.

Since it just won the Golden Globe award for best picture and several other garden blogs have commented on it, I think it’s time to take a break from blogging about nettles and weigh in on James Cameron’s Avatar. For the five or so folks who haven’t seen it yet, here’s a plot summary: An evil corporation sets up shop on a far off planet, “Pandora”, to mine a rare mineral necessary for the next generation of...

The Skunk Whisperer

Normally I ignore the business related facebook pleas filling up the Homegrown Evolution in box, but one came today that I had to grant some free publicity. We’ve all heard of horse whisperers and TV’s dog whisperer. You may have even heard of the chicken whisperer. Step aside for the . . . skunk whisperer, a “no-kill, no-trap” pest control company based in Oklahoma which seems to consist of at least two skunk whisperers,...

Gideon Lincecum Virtual Herbarium

–click to biggify– (If you still can’t read it, it says “Erigeron canadensis, the common hogsweed, bruise and press out the juice from the green plant and take it in tablespoonful dose as often as the stomach will bear, for bleeding lungs, bleeding from the stomach, bowels or womb. It is a powerful agent in stopping hemorrhage from any organ.”) Mrs. Homegrown here: Our friend Nancy gave us some salve made up o...

A Redneck Rocket Stove

From Wes Duncan, the “High Tech Redneck,” a rocket stove made out of cinder blocks. I’ve built one of these too and can confirm that they work great. And you can’t beat the price. Time for some redneck cookin’! Update: As several readers have pointed out, this design ain’t safe. Cinder blocks can explode and were not meant to be placed next to a heat source–that’s what fire bricks are for. See ou...
