Real Estate Bubble Bananas

There’s a house in our neighborhood that’s been for sale for over a year. Two months ago the for sale signs disappeared, junk mail littered the front porch and the mow and blow guys stopped showing up, leaving the lawn to go wild. A busted sprinkler head creates a nightly fountain as the houses’ infrastructure lapses into a timer operated zombification. We knew the nice young family that used to live here and I hope that they were able to sell somehow, but it doesn’t look good.

I started picking up the junk mail to make the place looked lived in. I also remembered that the backyard had both figs and bananas, and ventured beyond the gate to see how the fruit was developing (fyi, picking up fallen fruit is important to keep down the rat population). The figs aren’t quite ready but the bananas, the ones the squirrels didn’t get, were the tastiest damn bananas I’ve ever eaten. It turns out that our national real estate bubble has a fruit filled silver lining. I imagine that all across America there are abandoned fruit trees yielding their bounty for a new generation of gleaners. Thank you Angelo Mozilo for creating a literal banana republic!

Bananas are not my favorite plant for Southern California as they take a lot of water and get somewhat rangy looking when the wind rips up their leaves. But they are one of the most greywater tolerant plants and a good choice for paring with the outflow of a shower or laundry machine.

Fruit score: 10 to the squirrels 2 to the people

I’m sorry to say that I don’t know what variety this banana tree is, but June is a good month to plant bananas here in Southern California. Figuring out when to harvest bananas is tricky. Some yellow and mature on the plant (like my subprime banana) and others stay green and only mature after you pick them. Gardening expert Pat Welsh in her book Southern California Organic Gardening recommends picking one banana to see if it’s ready. For the pick-while-green, varieties (the majority of bananas) Welsh says,

“Pick their fruit when they’ve lost their sharp edges and indented sides; wait until they lose their angularity. When the fruit is still green but has become rounded, filled out, and fat looking, it’s ready to pick.”

Cut off the whole stalk of bananas and let them turn yellow in a cool shady place.

The past few days the Financial Times has started showing up on the driveway of this house so perhaps our neighbors were able to sell the place and the banana republic days are over. Looks like we’ll have to camp out with the in-laws in Phoenix for the subprime citrus harvest this winter . . .

Fish Don’t Fart

Portable Farms founder Colle Davis

Earlier this week we posted about home-scaled fish farming coming to a Home Depot near you. Yesterday we came across mention of another aquaponics supplier, Portable Farms (www.portablefarms.com) that produces larger greenhouse-based cultivation/aquaponics setups ranging in size from 6′ x 8′ to 90′ x 120′. The greenhouse seems like a good idea since, even in our warm Southern California climate, common aquaponics fish such as tilapia need heated water. Portable Farms owner Colle Davis runs a two acre farm in Escondido California and has been working on his aquaponics system for over 37 years. The tag line “Fish Don’t Fart” refers to the benefits of fish over methane generating cattle.

We skipped over aquaponics in our book since we considered it too expensive and complicated for most people. But perhaps we should give it closer consideration. Aquaponics is profiled in the pioneering urban homesteading book, The Integral Urban House: Self Reliant Living in the Cityand Scott Kellogg and Stacy Pettigrew’s book Toolbox for Sustainable City Living: A do-it-Ourselves Guidewhich comes out of their work at Austin’s Rhizome Collective. What all of these efforts have in common is a permacultural design principle of turning a waste product into a resource and closing a loop. Fish make fertilizer and plants clean water, so why not combine the two?

I’d like to hear stories from ordinary folks who have tried aquaponics on a small scale. If that’s you, leave a comment!

Chickens and Compost; A Match Made in Heaven

Before I got the chickens last year, I was already quite passionate about, or perhaps obsessed with, composting and fruit trees.

My composting area was way at the back of the yard ( I also keep three worm bins by the house for easy kitchen access). When we were deciding to put in the chicken coop we put it adjacent to the composting area. The composting area later became a part of the chicken run. There is a tangerine tree that is next to the compost that provides shade and protection to the hens. I never could have dreamed how well the chickens would fit in with composting and fruit trees!

They love eating fruit – pomegranates, figs, peaches, even oranges. The chickens make contributions to the compost with their poop, of course, but the real fun is when you turn it. Chickens are very curious- I’d say they are much more curious than my cats, who have disappointingly little interest in compost. I have to be careful where I plunge the pitchfork into the compost pile because the bird brained Peckerella (pictured) likes to be right in the middle of things. The chickens eat the bugs, grubs, worms and assorted creepy crawlies with glee. They scratch and peck and slurp up worms like noodles. It is a delight to behold. My father, who was very skeptical about the chickens at first, now loves to come over and watch them eat bugs from the compost. It is the best television show I know of, made right here in my own back yard. With the chickens, everything really comes together into a working system. They are also a lot of work and I worry that I’m overly emotionally attached to them. But over all, I am delighted with my backyard agroecosytem.

Vertical Micro-Farming

I was at Cal Poly Pomona the other day and saw this interesting display. The school has several small farm plots that demonstrate innovative or new practices, from hydroponic lettuce to intensive mini-orchards and now this strange setup. 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 peppers and there were others I can’t recall right now. I’m inspired to try to build one at home, since I’m always running out of space for my plants.

Farm in a Box

Farm in a Box ‘Little Tokyo

I never thought I’d see “permaculture” and “Home Depot” in the same sentence, but an article in yesterday’s Wall Street Journal (For a Green Thumb, Just Add Water) connects the dots between the two with a new product line called Farm in a Box Aquaponics from Earth Solutions.

Farm in the Box is a combined fish tank/planter box. Waste from the fish circulates into the planter box via a pump to provide fertilizer for the plants as well as removing nitrogen and ammonia from the water. From the Earth Solutions website:

“By integrating fish with vegetables, naturally balanced aquatic ecosystems are established making it unnecessary to add fertilizer, chemicals or remove nitrogen rich water.

As in nature, plants, fish and oxygen loving bacteria create a symbiotic relationship; Fish waste is converted by bacteria to a plant loving nutrient which helps maintain safe levels of ammonia without discarding waste and water.

Aqupaonics is an efficient, intensive gardening method with average of 3-6 fold greater yield per square foot. And even though water is everywhere in an aquaponic system, there is as much as 90% less water used than in-ground methods. Other advantages to aquaponics, is that it is fun, easy, most can be done anywhere, by anyone who shares a passion for locally grown food and herbs, without the challenges of in ground farming. Experiment with growing aquaponically raised fish and vegetables in your house on the patio in a greenhouse or community garden, and enjoy!”

Having never tried aquaculture I can’t say if Farm in a Box is a good idea or not, but it sure is interesting to see an advanced permacultural concept ending up in the isles of a big box store. If Home Depot wants to distribute a product like this or Nike wants to use fixed gear bike “culture” to sell shoes, I’m all for it. Let’s get the ideas out there. It’s up to us to take the next step and actually eat the fish.
