Laundry to Landscape 2.0

I just installed a “laundry to landscape” greywater system at the house of Lora “Homegrown Neighbor” Hall using greywater guru Art Ludwig’s free open-source plans. It was a cinch. And, thanks to a revision in the California plumbing code last year, it’s legal with no permit required.

I started in the laundry room by rigging up a three way diverter valve so that Lora can route the greywater back to the sewer if it’s been raining too much or if she’s bleaching her Prada (not likey, by the way). The diverter, somewhat of an exotic plumbing part, was ordered off of Ludwig’s website. At $47 it was the most expensive part of the system, but it’s well built.

Next, I rigged up two check valves, essentially a one-way gate, one to prevent greywater from siphoning back into the washing machine and another to act as a vent. You could also just use a six foot section of pipe as a vent, but Lora’s overhanging roof made that impossible.

The most labor intensive part of the process was digging the trench for the pipe out in the garden. Lora decided how many outlets she wanted in the garden and we consulted the “calculator” on Ludwig’s site (more of a chart than a calculator, actually, since he’s done the math for you). The calculator basically gives a range of outlet sizes and numbers so that you can get an even flow to the outlets but not risk burning out the washing machine’s pump. With nine outlets Ludwig suggests a 3/8-inch hole. We simply drilled 3/8-inch holes in the bottom of the PVC pipe that we ran out into the garden. The outlets flow into mini-mulch basins along the side of some perennial shrubs and a few small fruit trees.

Altogether it took just a few hours. Lora ran a load of clothes immediately and it worked perfectly. It was one of the easiest home improvement projects I’ve done. No cursing whatsoever! Now Lora can’t wait to do the laundry. She, of course, uses only Oasis Biocompatible Laundry Detergent. Note that many “eco” detergents will kill terrestrial plants–I’ll do a blog post on this shortly, as I discovered one major manufacturer claiming that a detergent was safe for greywater only to discover that it contained several different sodium compounds, definitely bad for soil!

Ludwig gives both a version of this project in PVC and another in HDPE plastic. I chose to work with the politically incorrect PVC since I couldn’t find the groovier 1-inch HDPE in less than 300 foot rolls. If any of you know of a source where you can get 1-inch HDPE by the foot, please let me know in the comments.

If you’d like to do this yourself the plans are all on Ludwigs site under Laundry to Landscape. In addition to the plans there is a parts list for both the PVC and HDPE versions and the aforementioned calculator.  If you don’t think you can do it yourself (remember it’s easy!) you could conceivably hand the plans to a handyman. A plumber would be too expensive, in my opinion.

The glass is half full–even if it’s full of greywater


Mrs. Homegrown here:

In this blog and in our books, we’ve talked a lot about the importance of accepting failure as part of the process of living a more homegrown lifestyle. Disasters of different sorts are inevitable. Sometimes they’re part of the learning process. Other times they’re acts of nature that you just have to shrug off. This year we’ve had lots of failures in the agricultural line. It’s been the theme of the year.

For instance, we lost the grape which covers our back porch to Pierce’s disease. No shade for us this summer. Then we had to pull out our citrus trees because there’s a new citrus disease in California, very similar to Pierce’s disease. We blogged about the crookedness and incompetence of the teams sent by the CDFA to intimidate people in our neighborhood into allowing them to spray our yards. Rather than allow them to apply imidacloprid to our vehemently organic garden, we’ve pulled the trees. They were young in any case, barely giving fruit yet. For all the Safety Theater going on, this citrus disease is not going to be stopped by spraying, only by breeding disease resistant varieties. So we figured we may as well pull trees which are doomed to die a few years from now anyway and replace them with non-citrus trees. Nonetheless, that left us with holes in our yard.

Then we had root nematodes in one of our garden beds, and crappy results in another for reasons still unknown. Our first batch of summer seedlings did not thrive, and had to be restarted, which has put us far behind. It’s almost July and our tomatoes haven’t even fruited. We planted our front yard bed with amaranth seeds, and a stray dog dug them all up. We planted a back bed with beans, and the chickens got loose and dug those all up as well.

But the other day I was looking at the photos stored on our camera, and realized that for all this, there were successes this year, and moments of plenty, beauty and grace. It’s far too easy to focus on the failures and forget what goes right. So from now on we’re going to document our yard and other projects more diligently, so that we can look back on both the failures and the successes with a clear eye. It did me good to see these photos, which I’m going to share with you:


The front yard isn’t looking bad. Not organized, but at least not barren.

Lesson the First: make weed-like plants the backbone of your yard, meaning edible plants that grow no matter what–which kind of plants will vary by region. Grow fussy annuals too, if you want, but have these survivors as back up. And learn how to cook them. For instance, we get nopales from that huge cactus that is swamping our hill. The cucumbers may refuse to set fruit, but the cactus pads offer reliable eating for several months, and then the cactus fruit forms, and we have a second harvest. Nopal is the gift that won’t stop giving.

Another fail-proof crop in this region is artichoke. I really don’t know why every house in SoCal doesn’t have one in its yard. Every year we eat artichokes until we’re sick of them, and the only downside is that they spread like mad, as you can see below:


But is that really such a problem? Too many artichokes? Oh noes! Ours grow happily entwined with fennel (which was too small at the time to be seen in the shot above). Fennel is another weedy survivor here. We can harvest the bulbs, or eat the flowers and fronds, or do nothing and just let the pollinators have at it. Today I was sitting by the fennel patch. The flowers are full of pollen, and the air above it looked like LAX: honeybees, wasps, orchard mason bees, tiny little pollinators that I can’t name, butterflies, ladybugs…. I’d need a fancy camera to capture all that action, but here’s a shot from the spring:


And then there’s always the reassurance of a sturdy old fruit or nut tree. Most of our trees are young–planted by us. They have yet to reach their productive days, but we have an old avocado tree. It bears fruit every year, but every 3rd year it gives a bumper crop. And this was one of those years. They’re the best avocados, too–buttery to the extreme. We literally do nothing for this tree, and it gives us this:


We had plentiful greens this year during our winter growing season, mostly turnip and beet greens, bitter Italian greens and Swiss chard. The hoops you see support light row cover material to keep insects away. Our beds look like covered wagons a lot of the time!


We’ve had some nice food this year, too, some of which was documented. Good to look back on.

A salad made with our greens, our pomegranates, and Erik’s notorious pickled crosne:


Or this salad of greens, avocados, nasturtium and arugula flowers, all from the yard:


Ooh..there’s this. Our carrot crop wasn’t big, but it was good. Yellow carrots. They got chopped up and roasted and tasted like candy:

And then there’s the creature comforts. Our chickens are doing well, still laying and haven’t been pecking on each other so much. I took this picture during one of their outings, when they were patrolling the herb bed:

Our dog is very old, so every day with him counts. There’s lots of pics of him on the camera, because he’s such a sexy senior citizen:


And there’s no comfort like a good Neighbor. Particularly one who carries a huge knife and knows how to use it:

And when the going gets tough, we can remember to take pleasure in the ephemeral. Blueberry flowers are worthy of haiku:


It doesn’t rain much in LA, and even when it does, rainbows are a rarity. But we had this one:


Life’s not so bad.

Pakistan Mulberries

Lora “Homegrown Neighbor” Hall was nice enough to drop off some freshly picked Pakistan mulberries (Morus macroura) gleaned from a house sitting gig. It’s one of the tastiest fruits I’ve ever had, very sweet, kinda like nature’s version of a Jolly Rancher. If you’ve never had a Pakistan mulberry it’s not surprising as it’s a fruit that simply doesn’t ship well.

Here’s what the California Rare Fruit Growers say about it,

“Originated in Islamabad, Pakistan. Extremely large ruby-red fruit 2-1/2 to 3-1/2 inches long and 3/8 inch in diameter. Flesh firmer than most other named cultivars. Sweet with a fine balance of flavors. Quality excellent. Tree spreading with large heart-shaped leaves. Recommended for the deep South and mild winter areas such as southern California, but usually performs satisfactorily in cooler areas.”

According to the Plants for a Future database the Pakistan mulberry is hardy down to -5 and -10°c and has both male and female flowers on the same tree. If I had the space, which I don’t, I’d definitely plant one.

That would have been the conclusion of this blog post had I not done an image search that turned up this:

Apparently chicks dig Pakistan mulberries or at least that’s the impression that a nursery down in Georgia (that I’m not gonna name cause the reviews are not so good) would like us to think. And the same nursery that generated the image above also has a page of religious videos, one of which (“The Cursed Fig Tree”) addresses the “God hates figs” controversy we dealt with some time ago. I can’t figure out if the videos are sincere, art, shot by kids, visionary public access or all of the above. We’ll leave it to post-structuralists readers of this blog wasting time at work to figure that out. 
Art theory tangent aside, damn, those Pakistan mulberries are good!
