In the Gutter

Our roofs, of course, are another impermeable surface that prevents rainwater from going where it should go–to our edible landscape. We can minimize the surface area by living in as small a house as possible and trying to maximize open ground. At our own compound we’ve even gone so far as to remove some previous resident’s bad addition and reduce the footprint of our house. So called green roofs, which have soil and plants growing on them...

Self Watering Containers

Today, something for our apartment homesteaders. If you’ve got a patch of sun and want to grow some food crops container gardening is the way to go. But container gardening has several drawbacks. Containers dry out quickly and if you forget to water, especially with vegetables, you can easily kill your plants. In fact inconsistent watering is probably the number one cause of container plant failure. Container gardening also uses a lot of...

Build a Washing Machine Greywater Surge Tank

After the shower, the next best source for greywater is the washing machine. Constructing what is called a surge tank with a fifty gallon plastic drum is the simplest way to reuse your washing machine waste water. Perfectly good water that would ordinarily just go down the sewer will instead water your plants after first spending a short time in the fifty gallon drum. Temporarily draining your washing machine into a fifty gallon drum has two adv...

More Washing Machine Greywater Fun

One of the problems with the washing machine surge tank greywater strategy is that what you are watering has to be downhill of the machine. This is a common problem with greywater systems, and trying to use pumps to get the water uphill is simply not economical, nor is it environmentally hip since those pumps have a lot of plastic and other icky industrial materials in them. Fortunately washing machines have a pump built-in and it’s possib...

3D Greetings

Homegrown Evolution’s holiday gift to our readers is a headache. Well, to be precise, we offer you three dimensional images of two of our favorite garden plants. Above, the prickly pear cactus (Opuntia ficus-indica) and, below, spearmint (Mentha Spicata). To view these two images in three dimensions follow these instructions, specifically the bit about “parallel viewing”. Be persistent, like all good things it might take some p...

Greywater Guerrillas in LA this Weekend

With the prospect of at least ten more years of drought here in California, greywater is a hot topic. This weekend Oak-town’s fabulous Greywater Guerrillas are heading down to Los Angeles for a weekend of talks and workshops. If you’re not in Southern California, make sure to check out their informative website and their new book Dam Nation. We especially enjoy the GG’s project examples. Here’s the 411 on their LA appeara...

Humanure Dry Toilet Made From a Milk Crate

Modern toilets take two valuable resources, water and nitrogen rich human waste, and combine the two to create a problem: sewage. In a dry or “humanure” toilet, you cover your deposits with a layer of non-toxic sawdust. Once the toilet is full you dump the contents into your outdoor humanure pile and compost the waste at high temperatures for at least a year. You can then use that compost as fertilizer for plants. The ubiquitous fi...

Made in the shade- Passive cooling

We just survived another major heat wave here. People and plants were positively melting. The sidewalks were veritable solar cookers. I’m sure I could have fried an egg on the sidewalk outside my house. I prefer not to crank the air conditioning, so I have been thinking a lot lately about simple ways to cool ourselves and the spaces we inhabit. Air conditioning is the main mechanical means by which we cool buildings these days. However, t...

Real Estate Bubble Bananas

There’s a house in our neighborhood that’s been for sale for over a year. Two months ago the for sale signs disappeared, junk mail littered the front porch and the mow and blow guys stopped showing up, leaving the lawn to go wild. A busted sprinkler head creates a nightly fountain as the houses’ infrastructure lapses into a timer operated zombification. We knew the nice young family that used to live here and I hope that they w...
