Pee on your Compost

Judging from comments and our web statistics you people out there love discussing poo. So it’s about time that we move on to pee. Why waste your perfectly good urine? Indeed, both Ghandi and Jim Morrison drank their own urine for it’s reputed health benefits. But we ain’t gonna go there. Our suggestion for the day is to save that piss for your plants. Urine is a fantastic source of nitrogen and it’s estimated that we all...

Showers to Flowers

...valve like the one pictured above, so that water can be shifted back to the sewer, if needed, such as during a long rainy period. Keeping the minimum fall rate in mind, run the pipe out to where you want to water. 3. Choose plants whose watering requirements match the amount of water coming out of your shower. To do this you’ll need to estimate how many showers and how much water you use per shower. Odds are it will be water hungry plants...

Water Conservation

.... The vegetables that we grow are irrigated with a water-saving drip irrigation system that we’ll describe in detail in a later post. We have no lawn, and other than the vegetable garden, all the other plants are either natives or from the Mediterranean, many of which are also edible. Reusing greywater from your shower and washing machine can also reduce the amount of outdoor water usage. Above all remember that lawns are the wasteful and e...

Vertical Micro-Farming

.... They sell the produce at the adjacent farm store. From looking at it I can tell that this setup is meant to utilize vertical space and grow vegetables in a small footprint. Water drips down from the top, irrigating multiple plants on its way down. The plants are not only stacked vertically, but radiate around the central axis, maximizing horizontal space as well. In this photo they are growing hot chili peppers. I also saw basil and sweet peppe...

Leaf Litter

...growth, inhibit soil erosion and may even stop acid rain from penetrating soil. For these reasons SurviveLA says banish your leaf blower! In fact, when planning a garden around permaculture principles you may want to consider plants that produce mulch, and placing them where the mulch will benefit your landscaping. Remember though that some trees such as black walnut and eucalyptus produce so called alleopathic chemicals that kill neighboring pla...

How To Stop Powdery Mildew

My winter squash has what Mud Baron once described as “jock itch for plants:” powdery mildew. I’ve tried all kinds of notions and potions in the past, but this year I decided to see what the science says about powdery mildew. Our climate where I live in Los Angeles is, unfortunately, ideal for producing this vexing fungus. IPM Let’s begin with some condensed advice from UC Davis’ Integrated Pest Management page: P...

A Prickly Situation

Today’s post is for clueless white folks as our hermanos y hermanas already know this shit. As we’ve suggested before the rule with landscaping at the Homegrown Evolution compound is, if you gotta water it you gotta be able to eat it. But there are a few miracle plants, well adapted to Southern California’s climate, that are both edible and don’t need watering. One of the most versatile is the prickly pear cactus, of whi...

Phytoremediation of Heavy Metals

...asoline and zinc from brake linings. These heavy metals don’t magically go away. They are elements, and short of an alchemical transformation you have to physically remove them, cover them up, or apply phosphate so that plants don’t take them up as readily. One promising strategy is phytoremediation, the use of plants to uptake heavy metals. youarethecity, in New York, is experimenting with Indian mustard, mugwort, basket willow and...

Getting Hardscaping Right

A water feature at Keeyla Meadows’ garden in Berkeley. One of the many lessons I learned on the tour I took of Bay Area gardens as part of the Garden Blogger’s Fling is that you’ve got to get the hardscaping right before even thinking about plants. When I asked garden designer Keeyla Meadows about the large stones in her garden she told me that they were craned in above the house. It was clear that at some point in the evolutio...

The tale of the worm bin celery

This is related to my recent post about our flowering radish. It’s a tale of botanic dumpster diving and another reason why you should let your food plants go to flower when you can. Last year I threw the crown (which is to say, the bottom) of a celery plant in my worm bin. I probably should have chopped it up for the worms’ sake, but I didn’t. Later, sometime in the fall,  I rediscovered the celery crown. Instead of rotting...
