Edible Rooftop Gardens

December 30, 2009

Homegrown Neighbor here:

As long as we are asking our readers for ideas, I have a few projects I could use your help on as well. I am looking for an edible rooftop garden to visit. Ideally it would be in Southern California, but I may also visit Austin, Texas. So either L.A. or Austin gardens would work. I’d love to hear from anyone who knows of a great rooftop edible garden, but I’d really like to find ones that I can visit.

The picture here is of an urban farm in Chicago that I visited this summer. It isn’t on a roof, but it is smack dab in the middle of the city and was pretty impressive.

And since I may be visiting Austin, I’d like to know of any cool projects or people I should visit there. Anyone who brews beer, builds bikes, does some serious composting, is an urban farmer or raises chickens would be great. And I’d love to see some community gardens. So Texas, I want to hear from you.

Leave a comment or email me at [email protected].

Thanks,

A tasty Italian chard: Bieta Verde da Taglio

A few folks have written to ask what we’re growing in our winter vegetable garden and we’ve been late to reply. Since we’re in USDA zone 10 and seldom get freezing weather here in Los Angeles, we can grow year round. One of my favorites this winter has been a Swiss chard variety from Italy called Bieta Verde da Taglio or “Green cutting chard”.

Verde da Taglio has thin stems and thick leaves. It ain’t as pretty as the rainbow colored chards we are also growing, but it tastes better, in my opinion. Steam it, fry it up with some garlic and olive oil and you’re set.

Verde da Taglio is sold by the Franchi company, which I have a brand allegiance to as fanatical as the worst Apple computer partisan. Is Franchi the new Apple? I predict we’ll see folks tossing their iPhones for packs of rapini way before that Mayan calendar thingy comes to pass.

We got our Bieta Verde da Taglio seeds from growitalian.com a couple of years ago and they are still viable. But, thanks to Craig Ruggless, our local Franchi seed representative, you can now find these seeds in some nurseries and stores here in California. You can also order from Ruggless via the catalog on his Franchi Seeds USA Facebook page.

I have a very exciting announcement to make. As you may recall, I volunteer at a school garden at North Hollywood High. Well, it is more than a garden. There is an orchard, a flower and herb garden, a pig and a goat. We are almost done with our chicken coop and hope to get some hens in there in the new year.

I have been trying to think of ways to raise money to support our school garden project. So we have partnered with one of my favorite seed companies, Botanical Interests, to fundraise for the school garden. If you click on the url above, or on the image in the sidebar and purchase seeds, a portion of the proceeds will go to support the garden project.

Botanical Interests is a family owned company. Their seeds are untreated and non-GMO. I have grown a lot of vegetables from their seed and I have always had great germination rates and healthy plants. They have a great selection of vegetables, herbs and flowers to choose from. My very favorite plant from their collection is the Italian Nero Kale. I eat huge, heaping kale salads from my garden on a regular basis. I didn’t used to like kale, now I love it.

And of course seeds make great gifts. Seed packets make great stocking stuffers, or cute adornments on packages. Botanical Interests also offers great collections of seeds such as a children’s garden collection and an heirloom tomato seed collection. What a perfect gift for any gardener or nature lover. So please, click through our website, tell your friends and buy some seeds!

Francine, our mascot pot-bellied pig, thanks you.

Without Merit: poison in your compost

An image from Washington State University’s aminopyralid bioassay instructions.

Another thing to worry about! In the past two years farmers and gardeners in the UK and US have experienced the unintended effects of a powerful herbicide called aminopyralid, sold by Dow Chemical under the brand names Merit and Forefront. This herbicide is used to control weeds such as thistle, knapweed and yellow starthistle.

The problem is that aminopyralid survives the digestive systems of animals pastured on land sprayed with it, as well as compost piles made from their manure. Most other herbicides break down eventually, but this stuff sticks around. An organic farmer using compost contaminated by aminopyralid could lose crops and organic certification for years. If that isn’t enough to worry about, two other nasty herbicides, picloram and clopyralid have also contaminated compost piles around the world.

But what about us backyard gardeners? How can aminopyralid effect us? I’m fond of using a bit of horse manure in my compost pile. It’s free for the taking and helps heat up the pile. But if the horses were fed hay grown on land sprayed with aminopyralid I could lose my veggies, particularly tomatoes, lettuce and legumes which are highly susceptible to this chemical.

So what can we do? First the practical: test your compost. Washington State University has instructions for performing a simple test here (pdf). Basically, you plant three pea seeds in a 50/50 blend of compost and potting mix and compare their growth against a control group of three pea seeds grown in just potting mix. If you use manure in your compost pile and you don’t own the animal it came from, this test should be routine.

Secondly, a political solution: the Rachel Carson Council suggests writing two EPA officials to suggest banning a trio of deadly herbicides that includes aminopyralid: Kathryn Montague at [email protected], and Dan Kenny at [email protected].

For more information on aminopyralid, picloram and clopyralid see the Rachel Carson Council’s Killer Compost Q&A.

Read the articles in Mother Earth News by Barbara Pleasant that tipped me off to this problem, “Milestone Herbicide Creates Killer Compost” and “Contaminated Compost: Coming Soon to a Store Near You.”

Here’s a technical discussion of aminopyralid for those familiar with biochemistry.

From Ohio State University, a fact sheet on the equally bad clopyralid and some charts showing the persistence of other herbicides.

Lastly, beware of the recommendations of agencies tasked with the eradication of invasive weeds. The California Invasive Plant Council, in a 2006 publication on Yellow Starthistle management (availiable here as a pdf), recommends using both aminopyralid and clopyralid and fails to warn of their persistence. The USDA, Department of Defence and the Army Corp of Engineers assisted with that publication. Looks like these agencies need a little reflection on the laws of unintended consequences.

Row Covers in a Warm Climate

The aftermath of a skunk rampage.

Here’s an unintended organic gardening chain of events:

1. Scoop up multiple trash bags full of fruit scraps from Fallen Fruit’s jam making event at Machine Project.

2. Add this large bounty of organic material to the compost pile.

3. Watch as a bunch of beetle larvae hatch and devour the fruit and other goodies in the compost pile.

4. Sift compost and feed most of the larvae to a happy flock of hens.

5. Add compost to the vegetable garden.

6. Plant seedlings.

7. Wake up the next morning to find out that skunks have spent the night rampaging through the vegetable beds in search of the remaining grubs. Yell in frustration at the sight of all the uprooted seedlings that took a month to grow in flats.

Now I knew that skunks were a problem at our place, and I had covered the beds each night with some spare shade cloth to keep them out. But on this particular evening I had forgotten to cover the beds. Pepé le Peu had destroyed a month’s worth of work.

Setting about to find a solution, I considered everything from high powered weapons to peeing off the front porch to spreading batches of compost for the hens to pick through. Not wanting a visit from the LAPD, I settled on floating row covers, a light fabric that is used to exclude pests and protect plants from frost. Row covers would also take care of another persistent problem, cabbage worms. But here in USDA zone 10, where we have only occasional frosts, row covers have the potential to make growing conditions too warm. Thankfully I was able to get a roll of an extremely light row cover material called Agribon 15. Agribon makes a range of row covers in varying thicknesses. Agribon 15 is the lightest and is used mainly to exclude pesky insects. It has also worked with the skunks, who seem unwilling to poke through the flimsy fabric. Those of you in colder places should use a heavier cover to retain more heat.

I drilled holes in the corners of the beds and bent some scrap PVC pipe to create hoops to hold the row cloth above the plants. Agribon is so light that you can just put it on top of many plants without hoops.
