Desert Victory Gardens

Inspired by empty grocery shelves and too much free time from sheltering in place, people rushed off to Home Depot to empty the shelves of gardening supplies. Many started their own "victory gardens." 

For you young'uns out there…Victory Gardens were made popular during WWII when people planted vegetable gardens to supplement their meager rations. The government promoted victory gardens as a way to support the war effort. They even offered a booklet to help first time gardeners. 

A peek at that booklet might be helpful.

1. Don’t start what you can’t finish. Before you start a garden, count the work involved even before seedtime and through to harvest. Abandoned gardens are a waste of seed, fertilizer, tools, insecticides and labor. 

Great advice. Wait! No mention of water? The writers obviously weren’t living in the desert during a 20 year drought and record heat wave!

When I think of Victory Gardens I think of my nana’s garden with perfect rows of vegetables. But nana lived on a farm in the Midwest where there was plenty of water. The gardeners of that age weren’t concerned about pollinators going extinct due to insecticides. They were blissfully unaware of the impact of climate change or fertilizer made out of fossil fuels. 

Check out number 7. Don’t let the pole beans block out the beets. In fact, don’t let any of the tall crops shade short ones whatever they are. Growing things must get sun. 

What!? They obviously haven’t watched their veggies wither and die in the scorching June sun. But I’m afraid many first time desert gardeners might.

There are lessons to be learned in the desert all around us.

Baby saguaros survive the harsh summer by sheltering in the shade of native trees like a mesquite or palo verde. They don’t call these trees “nurse plants” for nothin’. Our garden is shaded by two palo verde trees. Veggies grown under mesquite and palo verde trees also benefit from the nitrogen those trees fix in the soil. As far as those pole beans go, the Tohono O'odham demonstrate how the three sisters (beans, squash and corn) benefit from being grown together. The beans climb the corn and fix nitrogen in the ground, and squash leaves cover the ground to protect the soil and keep down weeds. After soaking beans for dinner, I'll plant a few under my young fruit trees for a nitrogen boost.   

Unfortunately, the giant eucalyptus tree that used to shade our entire backyard died this year. Now our baby fig trees suffer from direct sunlight. Taking advice from experienced Tucson gardeners, I've concocted shade contraptions out of tomato cages and some recycled shade mesh. No need to shade or water our native trees. Our desert hackberry, acacia, mesquite, and palo verde are thriving this summer with no additional city water. Yeah! The lesson from this is to plant native trees or heritage fruit trees that can take the summer heat!

One of our most helpful low-water gardening methods was inspired by early inhabitants in tune with their desert surroundings.

Back when the Santa Cruz River flowed year around, the Tohono O’odham practiced ak chin irrigation. When the monsoon rains came, the river would overflow washing nourishing silt over the flood plain. The silt would retain the moisture and replenish the soil. It would nourish the durable native seed crops they would plant in the floodplain. In a similar fashion we keep fallen leaves and apply organic wood chip mulch to nourish the soil and retain moisture in our garden and desert landscape. This traditional T.O. method also inspired the rainwater harvesting earthworks method of slow, spread and sink.

During the hottest month of June, before the monsoon season starts, I take my old fashion watering can out early every morning before it gets too hot and saturate the mulch around my young fig trees. If water rolls off the top of the mulch, I mix the water into the mulch with my hand and then pour more water into it. Using the watering can helps me keep track of how much water I use. 

NOTE: It’s even better to water them after it cools off in the evening so the water won't evaporate in the heat of the day. 

Pioneers survived droughts by treating each drop of water as precious. You may have seen westerns where the whole family used the same bath water. Gross! But we can use the same water twice. Dan and I carry our kitchen rinse water out to our hummingbird trumpets. A friend has an outdoor shower that waters his landscape. We use the greywater from our washing machine to irrigate our heritage fruit trees. 

We gleaned a great water conservation method from the Mexicans who built Tucson. They buried round ollas (unglazed terra cotta clay pots) in the ground and planted veggies around them. Water is poured into the opening on the top. That water slowly seeps through the pot into the soil. The roots of the plants wrap around the olla taking just the amount of water they needed. This saves a lot of water!

Nourishing the soil with compost, covering it with a thin layer of mulch and watering it with rainwater are desert gardening basics. To save water and have a healthy plant or tree, it's important to know how much water they require. Likewise, it's important to sow the right plant in the right season. Another tried and true technique is to plant short-season crops after the monsoons and use added rainwater to grow fast-growing favorites.

Sadly, it’s been a while since it’s rained in our yard. And the rainwater we collected in our water barrels is long gone. So I’ve had to resort to using more city water than I want to this summer. To offset that extra water use, I look for other ways to conserve water. Instead of a full shower, I often take what nana called a “spit bath” or sponge bath and then pour that water onto plants!

Nana would be proud.

Starting Where We Live

We plan to take out the rocks and use greywater to water our backyard. 

Glancing at the sweet Tree of Life Valentine card Dan gave me, brings to mind how we have grown together in the past two years. The Tree of Life represents our connection to each other, our community, and the planet.

After giving up on internet dating, I found Dan on Facebook. There were pictures of him mentoring teens in robotics, gazing fondly at his 3D printer, and painting the walls at CoLab workspace. I was impressed by how he was trying to do good in the world, so I asked him for a tour of CoLab. He rushed by me sweating profusely from riding his bike. After showing off CoLab, he offered to give me a tour of “his downtown” – Maker House and Xerocraft. We settled in the courthouse courtyard and talked for 6 hours. I told him about my creative boys, my screenwriting, supporting local filmmakers by organizing film events, and writing reviews of meaningful films. He told me in no uncertain terms that he wasn’t interested in dating. He came to Tucson so he could live inexpensively while working on his many humanitarian projects. The one that was dearest to his heart was “The Pineapple Project” a computer program that would allow subsistence farmers worldwide to use their cell phones to find out what was best to plant on their land.  

That's Gary Nabhan there. We're big fans. 

When we got together a few days later (yeah!), we struggled with finding time for us and all his projects. We are still working on finding the right balance. Dan soon discovered that he needed to apply his program closer to home, so “Sonoran Gardener” was born. Combining my interest in film and his in sustainability, we have gone to just about every sustainability or environmental movie event in Tucson! I even found ways to discuss environmental issues in my movie reviews at Reel Inspiration. 

The Poo looking guilty. 

While I have always recycled and have never driven, I am grateful to Dan for introducing me to sustainable living. It has added so much to the quality of our life together. In addition to not owning a car, Dan makes his own bread (lucky for me and the boys) and we are experimenting with planting heritage foods and edible weeds. (That’s right! Weeds!) The heritage Sonoran winter wheat is growing nicely, but the only one who has eaten any of it is “The Poo,” Dan’s dog. We did enjoy some purslane that was growing behind the neighbor’s fence. (I found a yummy Mexican recipe for a green sauce made of tomatillos, garlic, onions and serrano chiles!) We even tried planting purslane and some wild amaranth in our garden.  We may be the only ones who purposefully plant weeds in our garden!

Purslane (Portulaca oleracea).

Sometimes our environmental efforts conflict with each other. We would like to shop local, but not having a car makes it very time consuming to get to the farmers markets on the far end of town. We do cook some heritage foods that we purchased at Native Seeds:  like Tohono O’odham tepary beans. (Those stubborn little beans took over 24 hours to cook after soaking overnight!), and mesquite flour pancakes with prickly pear syrup. (Yum!) Dan would like to harvest his own mesquite beans, but they always fall to the ground before he gets to it. It’s hard being a programmer/gatherer!

Dan and I are great partners in living sustainably. Though we still struggle with developing daily habits. I squawk at Dan for leaving the water on while he reaches for a fork, “We live in the desert!”  I have learned to turn the water off while brushing my teeth! But I still kick myself for forgetting to bring the reusable grocery bag to the store.

Watershed management workshop.

We have found new ways to water our Tree of Life. Dan introduced me to the Watershed Management Group. We started with a lovely neighborhood tour. And we recently attended the Rainwater and Greywater harvesting classes. We are excited to redesign our yard so we can use washing machine water on our landscape. It’s sure to be hard work, but fun too!
