Flowers from Vegetables

Whenever possible I let vegetables go to flower, sometimes to save the seed, but more often to share the bounty with insects and birds. The usefulness comes in two waves: the first being the pollinators attracted to the flowers, and once the flowers go to seed the birds will move in. Of course this means that I’m “wasting space” and making my garden “unproductive” but the rewards outweigh any inconvenience.

New gardeners are often surprised to see what amazing flowers different vegetables make. People with no connection to food plants whatsoever may not even know that vegetables make flowers, so it’s fun to show them a carrot flower, a squash blossom, a bean flower.

My new favorite garden flower comes off an old Italian chicory plant left to go riot. I’m not sure which chicory it is, but it’s one of those  long-leaved, bitter greens beloved in Italy and sold by Franchi seeds. It’s easy to grow, pest proof, and we like the strong, bitter flavor. The flowers, though, are amazing. The greens send up narrow stalks 8′ tall or more (approx. 2.5 meters) and the stalks are covered from top to bottom with beautiful periwinkle blue flowers which are about 2″ (5cm) across– classic chicory flowers.

The bees adore these flowers. What’s more, this plant has been blossoming continuously for months now–at least 3 months. Unfortunately I didn’t mark down when it started, but it’s been at least 3 months by now, maybe 4. It’s given me lots of joy.

In our yard the flower stalks have interwoven with grape and bean vines, adding a lot of color to a corner of our patio. The situation is impossible to to photograph, because the flowers are both high and low and tangled up with everything, but trust me, in person it’s charming in its wild way.

In the fifth episode of the Root Simple Podcast we talk to Amy and Vince Stross of Tenth Acre Farm in Cincinnati, Ohio.

We begin with the story of why Amy quit her job and how she began to radically transform their yard. Some of the first work they did involved constructing berms and swales in the front yard, the only part of their property that gets enough sun to grow edibles. Amy and Vince describe the trial and error process they went through to perfect this water harvesting system.

We also discuss the beautiful result you see above–a front yard that combines edibles as well as flowers that both please the neighbors and provide habitat for beneficial insects. The magic extends out into the parkway which is planted with a cherry tree guild.

Amy and Vince go on to discuss how belonging to a CSA inspired them to cook from scratch and learn how to preserve food. This knowledge came in handy once their garden got really productive. Amy shares why buying a pressure canner is a good investment.

We talked to Vince about his post on making a non-electric mason jar vacuum sealer with an automotive brake bleeder. This is a cool and low cost alternative to the electric Food Saver vacuum sealer.

And Amy discussed her provocative post on why they don’t keep chickens.

According to Amy, homesteading is “more of a marathon than a sprint.” They are in it for the long hall.

We conclude by having Vince and Amy answer a Listener question about living a sustainable life in a cold climate (something we know nothing about!). Amy mentions growing fruit trees and freezing fruit in one pound packages. Canning projects then take place in the winter when heating up the kitchen also heats the house. Vince talks about growing greens year round and references the books of Elliot Coleman.

You can visit their blog at tenthacrefarm.com. Amy also does a newsletter (see the sidebar on their website). When you sign up for you’ll get a free ebook describing a little more about all the amazing things they are up to. We could have chatted for hours.

Biochar Results: Mixed

Biochar

Results from the first ever scientific study of biochar by researchers at the University of Southampton have been released. Plant growth was stimulated (up to 100%!) but,

the positive impacts of biochar were coupled with negative findings for a suite of genes that are known to determine the ability of a plant to withstand attack from pests and pathogens. These defence genes were consistently reduced following biochar application to the soil, for example jasmonic and salcyclic acid and ethylene, suggesting that crops grown on biochar may be more susceptible to attack by pests and pathogens. This was a surprising finding and suggests that if reproduced in the field at larger scales, could have wide implications for the use of biochar on commercial crops.

The researchers concluded:

Our findings provide the very first insight into how biochar stimulates plant growth — we now know that cell expansion is stimulated in roots and leaves alike and this appears to be the consequence of a complex signalling network that is focused around two plant growth hormones. However, the finding for plant defense genes was entirely unpredicted and could have serious consequences for the commercial development and deployment of biochar in future. Any risk to agriculture is likely to prevent wide scale use of biochar and we now need to see which pest and pathogens are sensitive to the gene expression changes.

Hügelkultur in dry climates?

Hügelkultur, popularized by permaculturalist Sepp Holzer, is the practice of burying logs in a mound to create a raised bed that composts in place. As the logs break down they add organic matter and create, in theory, a rich soil full of air gaps, fungal and microbial life.

But the thought of mounding anything in our dry climate doesn’t make sense to me. As I said in my post about the pros and cons of raised beds, if I didn’t have contaminated soil I’d grow my veggies in the ground. A Root Simple reader from Cyprus, which has a very similar climate as ours, said that Hügelkultur experiments there had not worked out. I’ve also heard that Geoff Lawton is skeptical of the practice in dry climates. And I’ve found no peer reviewed research on the practice.

But I also want to keep an open mind. I get asked about this practice a lot and have to confess ignorance. If you know of a Hügelkultur experiment in a dry climate please leave a link. Perhaps there’s a dry climate variation?  Has anyone seen any research? Have you tried it yourself?

Village Homes: A Model for Sustainable Suburbs

I’ve recently discovered a truly inspiring housing development in Davis, California. This is not new news–it was built in the 1980′s, but it’s new to me and worth sharing.

Village Homes is the brainchild of architect/developer Michael Corbett. It encompasses 70 acres and 200-some homes. It has all the space and privacy that brings people to the suburbs, but it’s designed with considerable intelligence. For instance, the homes are all designed according to passive solar principles, so their heating and cooling bills are considerably reduced. Some have even have green roofs. But more interesting is the landscaping, the massive network of bike/walking paths and the creative use of public space.

The entire development is essentially a big food forest. All of the rainfall is captured and instead of being directed to the sewer system, it runs to swales between the houses, to nourish fruit trees. The resulting space is a lush park full of edibles, from exotic jujubee trees to grapes to almonds. Residents can stroll around in the abundant shade and pick fruit at will. Only the almond crop is off limits–the almond crop is harvested every year and sold to support the the gardening services for the entire development. There are also community garden space available for those who wish to raise more food crops than their own yard space allows.  The lush growth coupled with the reduced asphalt surfaces makes the whole development 10 degrees Farhenhiet cooler in the summer than the surrounding suburbs.

I could go on and on, but perhaps the best way to get a feel for it is to watch the 10 minute video above. It’s hosted by Permaculture guru Bill Mollison, who’s a big fan of the development.  It’s well worth the time to watch it all the way through.

Also, here’s a short paper on the development, which gives all the pertinent facts, friendly for quick skimming: Village Homes: A model solar community proves its worth.

And finally, here is a video someone took during a site tour given by Michael Corbett, the developer. It doesn’t have as many visuals as Mollison’s video, but has some good insider tidbits in it, as well as discussion of some of the other features of the development, like office rental space and day care.

Asking the Right Questions

Golden Tree and The Achievement of the Grail

Sir Galahad Discovering the Grail by Edwin Austin Abbe (1895)

The legend of Percival’s search for the holy grail is an odd one. Spoiler alert! Percival finds the holy grail not through solving a riddle or answering a question. Rather, he asks the right question. In his first trip to the grail castle and the wounded Fisher King who oversees it, Percival doesn’t know what to do or say. It takes him years to find the grail castle again. On his second encounter (depending on the version) he either asks simply, “What ails thee?” or “Whom does the grail serve?” In this way, he finds the grail.

I was thinking about this myth this weekend in Larry Santoyo’s Permaculture Design Course when Larry stressed the importance of asking the right questions. It got me thinking about the kind of questions we need to ask about the many subjects covered on this blog.

Take for instance bees. Mainstream beekeepers ask, “How can I get more honey?” when they should be asking the same question Parsifal asks, “What ails thee?” That is, “What is in the long term interest of the bee’s health?” This is the question Michael Thiele and Kirk Anderson both ask. It’s a wise one to ask, since our health is inextricably entwined with that of the bees.

Or think about aisles of poisons and traps at all those big box stores. What if instead of asking, “How do I kill this pest?”, we asked, “How do I create conditions inhospitable rats/possums/raccoons/coyotes?” Maybe instead of buying poison (or worse, setting snares) we’d, for instance, stop leaving pet food out at night.

What questions do we ask in our neighborhoods? We often, myself included, ask questions such as, “What number do I call to anonymously report my neighbor for having a car up on blocks in the front yard?” A better question might be, “How do we foster the sort of community where neighbors aren’t strangers?” Communities where, if I have a problem with a neighbor I can simply have a civil chat because I know them and we’re friends. A short answer to this question, by the way: throw a party and invite the neighbors.

Like most legends there are many layers to the Percival story. Carl Jung considered it to be central to understanding ‘what ails’ Western civilization. Percival, according to Jung, embodies the reconciliation of the masculine and feminine, the logical and intuitive. But Percival’s quest begins and ends, not through some grand gesture, but through humility, through asking a simple question.

Before and After Permaculture

suzzanebackyard

An aspirational alternative to the future of jetpacks and space colonies I blogged about yesterday, came to me via the folks at Petaluma Urban Homestead. Noting that I said I was going to sit in on Larry Santoyo’s Permaculture Design Course (PDC), Suzanne of Petaluma Urban Homestead sent me before and after photos of her backyard saying, “This is what happened after I took my PDC!”

Radish Surprise

radish close

A volunteer radish–I think it is a daikon–sprouted up in a little clear pocket of our yard. We let it go, ignored it. It grew bigger, and bigger, and bigger. Usually a radish is harvested early, so we never see how big they can get.

This one got huge, then burst out into hundreds of tiny purple flowers. Hummingbirds, honey bees and all sorts of flying insects visit it all day, every day. It has become one of the queens of the garden.

The picture below is horrible. The radish plant really is quite pretty,  the equal of any ornamental flowering shrub–but as bad is the picture is, it gives you some scale. See the bales of our straw bale garden behind it?  I think it must be pulling water from there, which accounts for its size and longevity. It’s gone a little past its prime now– a couple of weeks ago the blooms were thicker.

By the way, radish blossoms are tasty food for people, too.
