Vegetable Garden Update: Too Much Salad

It’s amazing what you can grow in just a 4 foot by 8 foot area. From top to bottom in the picture above:

Escarole mix: Misticanza Di Indivie E Scarole
Lettuce: Lattuga Quattro Stagioni
Chicory: Cicoria Variegata Di Castelfranco
Dandelion Greens
Swiss Chard: Verde Da Taglio

Approximately half the bed is devoted to salad makings. Combined with another 2 foot by 4 foot area of arugula elsewhere in our yard, we’ve had a whole lot of salads this winter. Mrs. Homegrown would probably say too many salads. She’s also tired of me pointing out, each time I prepare a salad, that it’s made with fancy-pants Italian varieties.

But these greens are tasty and eye catching. Not even “Whole Paycheck” carries this stuff–you gotta grow it yourself. I got these seeds from the good folks at Winnetka Farms who run an heirloom seed store. I, pretty much, just call up Craig at Winnetka Farms and ask him what I should plant.

I grow salad greens by sowing the seeds densely in blocks and thinning as we eat. The dandelion greens and chard are started in flats and transplanted as John Jeavons recommends in his book How to Grow More Vegetables. I grow most of these cool season vegetables under a thin row cover material called Agribon-15 to keep out cabbage worms that go after the chard.

Stay tuned for more vegetable gardening updates including a few disasters.

Our Winter Vegetable Garden

Favas n’ peas

It’s a blessing and a curse to live in a year round growing climate. Winter here in Southern California is the most productive time for most vegetables. It also means that there’s no time off for the gardener or the soil. In the interest of better note keeping, what follows is a list of what we’re growing this winter in the vegetable garden. We’ll do an update in the spring to let you know how things grew. For those of you in colder climates these would be “cool season” vegetables and it’s never to early to start planning.

For just about the tenth season in a row we’ve sourced all of our seeds from two venerable Italian companies, Franchi and Larosa. Why? You get a ton of seeds in a package and they’ve always, without exception, germinated well and yielded beautiful vegetables most of which can’t be found in even the fanciest restaurant in the US. Frankly, every time I try another seed source I’m disappointed. I also like Italian cooking with its emphasis on flavorful ingredients prepared simply–no fussy sauces or complicated recipes.

Salad Makings

First off an endive and escarole mix from Franchi Seeds recommended and sold to us by our friends at Winnetka Farms. Looking forward to this one.

“Cicoria Variegata di Castelfranco”
A  bitter and beautiful chicory, also recommended by our Winnetka pals along with:

“Lattuga Quattro Stagioni”
A butterhead type lettuce.

Arugula “Rucola da Orto” from Larosa seeds.
You can never plant enough arugula, in my opinion.

Greens

Rapini “Cima di Rapa Novantina”
I grow this every year. It’s basically my favorite vegetable–much more flavorful and easier to grow than broccoli.

Spigariello broccoli.
A large plant resembling kale. You eat the leaves and flowers. Used in “Minestra Nera” or “Black Soup,” which consists of this vegetable and cannelini beans. More info here.

Fava and bush peas
I’ve rotated in legumes in the bed we grew tomatoes in during the summer. The fava came from seeds saved by the Winnetka farm folks and from our own garden. The bush peas are “Progress #9″ from Botanical Interests.

Chard “Bieta Verde da Taglio”
A tasty, thick leaved chard from Franchi seeds.

Dandelion greens, “Cicoria Selvatica da Campo”
A truly idiot proof vegetable. Bitter and easy to grow.

Parsnips “Prezzelmolo Berliner”
The first time I’ve ever tried to grow parsnips.

Radishes “Rapid Red 2 Sel. Sanova”
Mrs. Homegrown complains that I never plant radishes. This year I addressed that grievance.

Beets “Bietolo da Orto Egitto Migliorata”
A repeat from last year, these are tasty red beets.

Buck’s horn plantain also known as “Erba Stella”
An edible weed.

Stinging nettles
One of my favorite plants. It’s begun to reseed itself in the yard. Useful as a tea and a green.

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 with runoff from an automated drip system. The sacks are calcified with irrigation scale. Even in an open-air setting, get close and there is a whiff of mold. It’s hard to imagine a less savory or more whimsically destructive system for a region in a water crisis.”

Amen. We need more critical thinking like this, especially when it comes to schemes with “eco” or “sustainable” pretensions.

Plantago coronopus, a.k.a. Buckhorn Plantain, a.k.a. Erba Stella

Cruise down the produce isle of a supermarket in the United States and you’ll only find highly domesticated foods. Thumb through the pages of the Silver Spoon (the Joy of Cooking of Italian Cuisine) and you’ll discover entire chapters devoted to the use of wild or semi-wild plants.

This summer I grew one of these semi-cultivated Italian vegetables, Buckhorn plantain (Plantago coronopus) also known as Erba Stella and Barba di frate (friar’s beard). It’s a mild, ever so slightly bitter green I found delicious boiled and sauteed with garlic and olive oil. The Silver Spoon suggests cooking it with either pancetta or anchovies.

As for growing Plantago coronopus, let me put it this way, if you can’t grow it consider giving up gardening. I left some in my seedling flat and, with just three inches of soil, it produced a viable crop. It’s a weed. While I’ve seen it described as a cool weather green, it grew fine this summer (admittedly a very mild summer here in Los Angeles). Do an English language search for this plant on the interwebs and you’ll get tips on the right herbicide to use to rid your lawn of it.

Another winner from Franchi seed company!

Staking Tomatoes with Concrete Reinforcing Mesh

For years we’ve been using concrete reinforcing mesh to stake our tomatoes. It’s a 6-inch square grid of wire and is used to reinforce concrete slabs. I buy it in 3 1/2-feet by 7-feet sections at my local home improvement center. To make a tomato cage with it you find a flat stretch of patio or driveway and bend the wire into a tube. I overlap it a bit and tie it together with wire.

This year, thanks to a tip from Craig Ruggless, I decided to double the height of the cages using two per plant to make them 7-feet high. As the plant grows, you simply tuck the vines into the cage, with no pruning necessary. But you do have to stay on top of the tucking, otherwise you risk breaking off stems. Since a 7-foot cage can be very top heavy I staked them deep into the ground with some rebar I had laying around. Long wooden stakes would work just as well. You could also choose to grow shorter tomato varieties. The San Marzano tomatoes in the middle of the picture above are half the height of the other two and way more productive.

Another staking option is to buy Texas Tomato Cages for $99 for six 24-inch by 6-foot cages. The advantage with the Texas cages is that they fold flat when not in use. The disadvantage is the price. If you buy your concrete reinforcing mesh in bulk, on long rolls, the price would be significantly less than the Texas Cages and I think reinforcing wire is just as attractive if rolled carefully.

I would avoid the tiny, flimsy conical cages I’ve seen for sale at most nurseries as almost every tomato plant will easily outgrow them and stems will break as they spill over the top.

For a roundup tomato staking techniques see the Santa Clara County Master Gardeners website.

Foreclosure Garden Foreclosed

Neighbor, artist and master gardener Anne Hars took over the front yard of a foreclosed triplex earlier this year and planted a vegetable garden. The triplex had fallen in to disrepair and had become notorious for housing a bunch of gang members.  The police evicted the gangsters and the building fell into disrepair.

The garden Anne planted in the spring had just begun to bring forth its bounty.

Then, this past week, an unpleasant man showed up claiming to work for Bank of America.

That was the end of the garden.

As Anne put it, “this is how the banks take care of their property…”

Read the whole saga on Anne’s blog, theforeclosuregarden.blogspot.com.

Magenta Spreen Lambsquarter

Magenta Spreen Lambsquarter (Chenopodium giganteum a.k.a. “tree spinach”) has reemerged in our garden via the compost pile. It’s a striking edible weed, part of the family that encompasses spinach, quinoa and epazote. Seeds of Change sells this beautiful variety, oddly named “Magenta Spreen.” Like other members of the Chenopodium family it has a fair amount of oxalic acid which could be a problem if it’s all you ate. Even though I’m prone to kidney stones I’m not concerned about oxalic acid in moderation. Cooking reduces oxalic acid as well as saponins that the leaves also contain.

The Plants for a Future database entry on Chenopodium giganteum has a few cultivation details,

“An easily grown plant, succeeding in most soils but disliking shade. It prefers a moderately fertile soil. This species is closely related to C. album, and was probably derived from it through cultivation. The tree spinach is sometimes cultivated for its edible leaves, there are some named varieties. ‘Magentaspreen’ is a vigorous plant growing 1.5 metres tall. It has large leaves, the new growth is a brilliant magenta colour. Tastiest when young, the leaves are eaten raw or cooked like spinach. A warm climate is required in order to ripen the seed.”

Chenopodium giganteum has a tendency to become invasive, but I prefer to think of it as what Craig Ruggless of Garden Edibles calls a “happy wanderer.”

Vertical Vegetables

Frederick Law Olmstead’s office has a 19th century “vertical garden.” Vines!

I was somewhat dismayed to see a local newspaper article touting a company that sells a $1,000 vertical vegetable garden system to schools. The company has a plan to sell this system nationwide. The problem is that I have serious doubts about the long term viability of vertical garden walls for a number of reasons: irrigation, maintenance and start up costs just to name a few. And I’m not alone. The New York Times did some critical reporting on the subject of vertical garden systems in a recent article, “Gardens That Grow on Walls.”

For certain plants vertical growing might work. I haven’t tried it, but this DIY vertical succulent garden in Sunset Magazine certainly is striking. But vegetables? Their roots need space and you’d need to do a lot of watering to keep a vertical vegetable wall happy.

All New Square Foot Gardening: Grow More in Less Space!But growing vertically does not have to mean attaching roots to a wall. I can think of two simple vertical vegetable garden strategies where that $1,000 would go a lot further. How about simply favoring fruits and vegetables that either grow vertically naturally, say pole beans, grapes, peas or kiwi or that can be convinced with a bit of pruning to go vertical, such as tomatoes, melons and winter squash? Mel Bartholomew has some nice vertical gardening tips in his classic book Square Foot Gardening: Grow More in Less Space!. Build some raised beds next to a wall or saw cut out the concrete, plant in the ground and you’re in business.With some slings for the fruit, you can even grow watermelons vertically.

EARTHBOX GARDEN KIT GREENAlternately, buy or make some self irrigating planters (SIPs) and put them next to a wall. See the Green Roof Growers for what can be grown vertically with SIPs made from scavenged five gallon buckets. Or you can buy a commercially made SIP kit from the Earthbox company for around $50. The nice thing about SIPs is that they are fairly idiot proof and easy to maintain. A SIP is as close to “plant and forget about it” as you can get with vegetables. In short, perfect for schools where maintenance is always an issue.

As one of the vertical wall landscape designers admitted in that New York Times article, “in nature, you don’t have vertical dirt.” Why fight nature?

Growing and Preparing Cardoons (Cynara cardunculus)

It’s the ultimate pain in the ass vegetable to prepare and I’ll probably get in big trouble in native plant circles for even mentioning it, but just last night I fried up my first successful plate of homegrown cardoons (Cynara cardunculus).

Not the most attractive blanching job, admittedly.

All ready to prepare

The cardoon is a close relative of artichoke, identical in appearance, except that the flowers are much smaller and the plant tends to get a lot bigger. Instead of eating the flowers, as with artichoke, you eat the stems. But first you’ve got to take some extra steps. When it gets around 3 feet tall you tie all the stems together and cover it in cloth, burlap or newspaper to blanch it for two to three weeks, leaving the top few inches of leaves to poke out of the covering. I once tried to eat an unblanched stem and it was bitter and tough so, in my experience, the blanching is a necessary step.

Pullin’ off the stringy bits

To prepare it you take the blanched, tender inner stems and pull off the stringy bits on the back, being careful to avoid the sharp edges (did I mention that this is a pain in the ass food?). Chop the stems into two inch strips and drop them into acidified water to prevent discoloration. Next boil the crap out of them. You might also be able to bake the crap out of them, but I have not tried this. I boiled them for 25 minutes. After boiling I fried them in a pan with garlic and olive oil and topped them with salt and Parmesan cheese. They are somewhat bland with a faint taste reminiscent of artichokes. They’d probably taste better paired with a heavy meat dish or as part of a stew. I’ve also seen recipes where they are drenched in cream and cheese.

In our Mediterranean climate cardoons are a perennial, though if you harvest them they’ll effectively be an annual. Here in Los Angeles you plant them in the winter/fall for a spring/summer harvest. The cardoon I harvested was “dry farmed” with no supplementary irrigation and planted itself. Elsewhere you would plant them a couple of weeks after the last frost and blanch them before they get too big.

When I mentioned to a native plant expert I greatly respect that I had them in my garden she read me the riot act. Cardoons are remarkably resilient and invasive. Hailing from the Mediterranean, they’ve taken over large parts of the New World. The brilliant purple flowers release thousands of tiny seeds, each with their own fibrous parachute that caries them hundreds of feet in the slightest of breezes. Charles Darwin mentions cardoon in The Voyage of the Beagle,

“In the latter country alone [Uruguay], very many (probably several hundred) square miles are covered by one mass of these prickly plants and are impenetrable by man or beast. Over the undulating plains, where these great beds occur, nothing else can now live.”

My own thoughts about “invasives” are closer to David Theodoropoulos than the nativists–best to work with invasives rather than fret about them. Homo Sapiens are the ultimate invasive species, after all, and I’ll take the cardoons over the oil spills, any day.

Seedling Disaster!

“No one talks of failure as anything but shameful; this is wrongheaded and foolish . . . Mistakes are synonymous with learning. Failing is unavoidable. Making is a process, not an end. It is true that deep experience helps avoid problems, but mainly it gives you mental tools with which to solve inevitable problems when they come up.”

-Tom Jennings, as quoted in Mark Frauenfelder’s excellent new book, Made by Hand: Searching for Meaning in a Throwaway World 

Oh, but those mistakes sure can be frustrating especially when they happen in the garden!  I’ve had nothing but bad luck germinating seeds this spring for our summer garden and, as a result, our vegetable beds are as bare as the Serengeti. What happened? Here’s a list of possibilities:

  • watering too much
  • watering too little
  • damping off 
  • unseasonably cold weather (we germinate outside here)
  • the occasional hot day on top of cold evenings
  • the mindset of the gardener: being in a hurried, stressed mood as we finished our next book

Nature being a complex system, you can often get stacking problems that make figuring out what went wrong difficult. I’m leaning towards the cold weather as I’ve noticed some of the seeds I planted starting to come up as it has warmed up. Lesson: you’ve gotta watch the weather reports even in a mild climate such as ours or invest in heating mats or a cold frame. 

Despite my pledge to grow vegetables only from seeds, panic over a summer without homegrown tomatoes prompted me to call Garden Edibles owner Craig Ruggless to see if he had any seedlings. Thankfully he had some heirloom tomato seedlings that he gave to me in return for helping him try to capture a swarm of bees that had shown up in his olive tree (unsuccessfully, it turned out–more on that misadventure in another post). At least I’m not alone. My friends in Chicago, the Green Roof Growers, had their own tomato seedling apocalypse.

I once saw Julia Child on Martha Stewart’s show demonstrating how to make an elaborate dessert called a Croqembouche, a pyramidal tower of cream filled pastry balls. Stewart and Child built separate Croqembouche towers. At the end of the demo Stewart’s was perfect and Child’s was, well, a big mess. Yet Julia soldiered on, laughing at her mistakes. My pledge with the garden is to try to do the same and have fewer of my notorious garden meltdowns when the inevitable crisis happens. So what if it ain’t perfect around here? Now Mrs. Homegrown and Homegrown neighbor should make note of that pledge . . .

Readers, please feel free to share some recent disasters.
