"Golden Sweet"

We are now well into the growing/fighting season. I had fully intended to make frequent updates on the garden, but with the store move my time and energy was required elsewhere. It is now late June and we have enjoyed a handful of “Golden Sweet” cherry tomatoes, one “Black Krim” heirloom tomato, and a few baby yellow crook-neck squash.

This is our first garden in Tulsa and after having much success with our garden in Norman I was excited to begin gardening again. This time around has taught me a lot more, but has not been so easy.

We prepared the beds with mushroom compost, bat guano, bone meal, peat moss and worm castings to provide fertile soil that held moisture and would feed the plants. For the tomatoes I also used about 1 1/2 aspirins in the surrounding soil to increase disease resistance. The plants came from the Oklahoma Food Coop, the Living Kitchen, and Southwood. While all of the plants have been really healthy, next year I would like to get most from the Living Kitchen as my tomato plants from them started of as the smallest and have wound up as the biggest with the highest yield.

dsc03644-640x480All was well, the plants were strong and healthy and growing rapidly. The battle began the end of May/beginning of June with an aphid outbreak on the tomatoes. To begin with I just squished them with my fingers, then I used a neem and fish oil, then I purchased some lady bugs from Garden’s Alive. The lady bugs did a great job of devouring what was on the plants before flying off to their new homes. However, a week later I had another outbreak. At that point I concluded that the best and most cost-effective method of aphid control was the “squish with fingers” method. For about a week I spent 45 minutes in the morning and evening squishing the little buggers. Then the heat set in and I have not seen anymore since. If we had too many more plants the “squish” method would not be a very viable option, but with 6 plants it is doable. Then I noticed some mites on the new blossoms. Mites are so tiny it is near impossible to squish them all so I got out the neem oil and fish emulsion sprayed each blossom which seems to have handled the mite problem.

Along with visits from aphids was the appearance of flea beetles on the eggplant leaves. Research revealed manual control to be best for these pesky little jumpers. So out came my “bug vacuum” the only battery operated, plastic toy that I truly love. I have used this little guy for everything from crickets to rolly pollies inside the house to flea beetles, squash vine borer moths, and spotted cucumber beetles in the garden. It is a great tool that every organic gardener should own (in my opinion). After the main flea beetle population was under control I have tossed the vacuum to the side and simply squish on the spot.

At this point I noticed some wilt happening with the squash. After further examination I noticed various places with a saw dust-like frass and the fight against the squash vine borer was on. In hindsight I realized that I had actually seen the moths and even captured one, but had come to the conclusion that it must have been a wasp of some type that would be good for pollination and let it go… oops! Squash vine borer is the most pesky of pests as the adult lays 200 tiny reddish brown eggs one-by-one ,the eggs hatch in 5 to 7 days and out comes a minuscule little worm that will burrow into the the stem and proceed to turn everything in its path to mush. Some of the eggs will be deposited on the tops of leaves, others on the underside, others on the leaf stem, some on the squash blooms, and some on the main stem. I ended up with nothing short of an infestation.

Once I realized that the evil squash vine borer was attacking my plants, I saw the tiny reddish brown eggs everywhere and began to pick them off one-by-one. At this point I noticed the frass and read that once inside your plant the only controls (organic or conventional) were to destroy the worm via removal or to inject beneficial nematodes or neem oil into the stem. Both methods were reported to be tedious so I got out the scalpel and commenced the operation. After hours of making vertical slits in the plant and removing at least 20 worms (some as long as and inch and a centimeter thick) it seemed as if the operation was a success. But wait, the eggs are still appearing and daily I find another grub-like worm to remove. With the heat, worms, and stress from multiple operations I have almost completely lost the acorn squash and yellow crook neck.

dsc03640-320x200My zucchini seems to still be hanging in there as squash vine borer is not as attracted to zucchini as acorn and yellow. However, it is not pest-free as the spotted cucumber beetle has been hanging around the various squashes eating a few here and there.

And now it is the time for the tomato worms to show up and I have already picked 3 off. I caught the three fairly early after spotting some droppings and searching diligently on leaves, stems, blossoms, and fruit. I could use some BT for worm control, but first I want to see how far manual control will get me.

I have no idea where all these pests are coming from, it is strange to me that my new little garden has attracted every type of pest imaginable.  The lessons I have learned for next year are many but can be summed up by this:  I live in a neighborhood infested with garden pests and need to be more aggressively proactive. So what will I do next year? Well, I really want to install a bat house or two and cultivate a ladybug, bee, and butterfly garden. Additionally I will be prepared for spotted cucumber beetles and squash vine borers with yellow sticky traps (possibly with pheromones). Since our peach tree may produce next year, I will also be prepared with peach tree borer traps. I have not yet decided if i want to use row covers or not. Floating row covers are a great way to keep pests off, but do not allow the pollinators access to the plants. Without pollinators, crops are still possible but you must hand pollinate. From my current stand point hand pollinating sounds much better and more efficient than what I have just been through.

As for watering… this year we had planned to integrate deep-pipe irrigation to the garden. Moving the store and getting the plants in the ground all hit at the same time and we were not able to install our bamboo irrigation system. We do have the supplies and will be going forward with the experiment in water conservation next spring.

While I have encountered several problems, the garden still serves as a major de-stresser. I love getting my hands in the dirt and helping my plants to produce beautiful organic produce. Gardening organically also gives me a deep sense of peace knowing the I am not breathing in or absorbing any toxic chemicals nor am I contributing to the chemical pollution that is ever so prevalent in our world today.  I am open to learn all the lessons that a garden has to offer and enjoy cultivating a deeper connection with the natural world.

HAPPY ORGANIC GARDENING!

New Website: Food, Pesticides & Toxicology

Today I ran across the new website from the Pesticide Action Network, What’s On My Food? This website uses a formula similar to that on the Skin Deep Database only in relation to chemicals on food and the documented research on those chemicals rather than chemicals in skin care items. It is a great resource to click on and see the various chemicals that the USDA’s Pesticide Data Program has found in various foods cross referenced with data from the EPA and authoritative research.

Pesticide regulations in the U.S. are well behind much of the rest of the industrialized world. This is mostly because agrichemical corporations like Monsanto have too much influence in Washington, but also because pesticide regulation in the U.S. does not adequately account for things like additive and synergistic effects.

Since the Environmental Protection Agency (E.P.A.) regulates most chemicals on a chemical-by-chemical basis, the combined and cumulative effects of a mixture of pesticides are nearly impossible for them to address – and so they usually don’t. 1

In addition to this handy tool, they have  a lot of really great information and links to research. They have links and document the growing body of research on the effects of pesticides on human and environmental health from the various exposures: working or living near crops where pesticides are used, prenatal exposure, exposure through food, and exposure through runoff into streams, rivers, aquifers, lakes, and oceans.

Given the complexities of chemical causality and disease-formation, the smart solution would be to follow the European Union’s lead and adopt the “precautionary principle”2 as the basis for regulatory decision-making. Put simply, this approach prioritizes protecting human health when there is significant doubt about the safety of a product. By contrast, pesticides and industrial chemicals in the U.S. are innocent until proven guilty. It often takes decades to prove a chemical guilty.

Meanwhile, we are exposed to dozens of pesticides in the food we eat, water we drink and air we breathe. People working on farms or living in rural areas near non-organic agricultural fields face even higher exposure levels.

My transformation from someone who lived very chemically intensively to someone who works diligently to reduce the amount of chemicals in my life and the lives of others began in 2005 when I began to work with children with autism. When sifting through the research on autism it is impossible to ignore the various research linking chemicals to the condition. Then your mind stats to wonder about the rise in other health-related issues: Parkinson’s, cancer, asthma, depression, ADHD, pre-term births, endometriosis, infant mortality (to name a few). As you dig deeper and deeper the research presents a not so great picture. Instead of pull myself into isolation in some remote village less damaged from chemical pollution, I decide to do what I can and help others to realize the need to reduce the amount of chemicals we currently support through our consumption patterns.

To begin with I eliminated all chemicals from my house: the pesticides I used in the garden, the cleaners under the sink, skin care products, perfume… Then I saw the need to eat as organically as possible for me, my unborn children, and millions of farm workers around the world. And then I took a good hard look at my clothing and the textile industry and realized that if I were to buy new supporting organic cottons and sustainable fibers was the only way to go. Conventional cotton uses 25% of the world pesticides and if I truly want to live my life in a way the respects the quality of life and health for all there is no way to justify not supporting the more sustainable options. Once you see the world as a contained system in which we are all connected and realize the ill effect that can be cause by a single shirt the organic and sustainable textile industry becomes a pivotal part in the quest for a better future.

The following is an excerpt from the What’s On My Food Website:

How are we exposed?

» In our bodies
» On the farm
» In the environment
» On our plates

In our bodies

Most of us are born with persistent pesticides and other chemicals already in our bodies, passed from mother to child during fetal development. The human health impacts linked to pesticide exposure range from birth defects and childhood brain cancer in the very young, to Parkinsons’ Disease in the elderly. In between are a variety of other cancers, developmental and neurological disorders, reproductive and hormonal system disruptions, and more.

On the farm

Most of us are born with persistent pesticides and other chemicals already in our bodies. Farmers and farmworkers are some of the hardest working people on the planet. Yet they and their families bear the highest health costs and face the greatest risks of pesticide exposure. Farmworkers in particular remain the least protected class of workers in the U.S. – last year another slavery case was brought in Florida on behalf of farmworkers there. Poisoning incidents among farmworkers are vastly underreported – yet in California alone, hundreds of cases of pesticide poisoning are documented every year.

Occupational exposure to pesticides in acute cases range from dizziness and nausea to death; chronic exposures are linked to the same array of diseases listed above plus a few more listed below.

In the environment

Pesticides don’t stay where they’re applied. They drift from their target and are carried in our air, oceans, rivers, groundwater and soil. They contaminate ecosystems and can poison fish, birds and wildlife. Water supplies around the world contain measurable amounts of pesticides, including atrazine. Atrazine, a suspected endocrine disruptor recently banned in Europe3, is the most commonly used herbicide in the U.S.

Besides heavy use in industrial farming, pesticides are used in or near playing fields, parks, schools, public gardens, golf courses, grocery stores, offices, apartment buildings, hotels and resorts, airplanes, cruise ships — the list goes on. Rural communities are routinely contaminated by pesticide drift, while city dwellers may trace pesticide residues on their shoes to public parks and even their apartment’s common areas.

And Now for a Little Organic Gardening

For those of you who do not know, Jeremy and I moved from Norman to Tulsa in the fall of 2007 with plans of starting a family. We left behind a wonderful organic garden, norman-squash-and-zuchinnifrom which came the most beautiful and delicious squash and zucchini, and some lovely flower beds. Our intention was to move into the house, green it up, put in a garden, add some color to the flower beds, and start a family. But fate had other plans for us. The house green-up was a little more intensive and time consuming than we had imagined and then came Lundeby’s Eco Baby and two puppies. All bets were off, it was a challenge just trying to take care of the store, the laundry, and the animals. The house was rarely clean and home cooked meals were becoming a distant memory. With the passing of time, the clean house and home cooked meals started to return as our new life began to take hold. So now it is time to start some new projects! Enter the beginning of our small urban farm. compost

We loosely constructed a compost bin out of some wire fencing and an old piece of wood; not the most beautiful, but it does the job by providing containment and adequate ventilation. In our compost are some fall leaves from the trees in our front yard, vegetable and fruit scraps, eggshells, and rabbit droppings. The rabbit poop comes from Fatso, our house rabbit who is our oldest family pet.  fatso-tulsaBehind the compost bin is one of the two 4′ by 8′ plots that we will start this spring. In Norman we constructed a no dig garden, but here we decided to clear the sod and loosen the soil a bit before building the raised bed. The next step was the construction of the raised beds. For which we decided to use cedar wood due to its bug repellent properties and nice warm color.  Next we filled the beds with a mixture of topsoil, peat moss, and mushroom compost. Our compost is not quite ready to use yet, but I did throw in a couple of hand fulls for good luck. The cedar post running across the yard will serve as a fence to keep the dogs and their droppings away from the garden and just on the other side is a newly planted peach tree for future shade and fruit.

garden-beds-ready

Now for the fun stuff, planning the garden. Organic gardening is much easier if you plan ahead and utilize optimal soil with a high organic matter content, water conservation, and companion planting. For our Norman garden we used drip irrigation, but seeking to find a watering source with less pollutants than the recycled tire hoses we found an even more efficient source for watering, Deep Pipe Irrigation using bamboo . Our bamboo is here and ready to be prepared for the garden (an experience I will definitely blog about). Companion planting is the practice of placing plants that attract beneficial insects, repelling pests, and or improve quality and flavor of another plant and equally important distancing plants that do not have a beneficial effect on one another. There are many resources for companion planting online here are a couple with a good basic overview Home and Garden Site and Golden Harvest Organics andTinker’s Gardens has a nice easy to follow chart. So far I am planning for beans with rosemary and possibly a petunia; zucchini and squash with marigolds, nasturtiums, and borage; eggplant with some contained catnip (potted and planted), and a few strawberries with some nasturtiums. Currently the plan is to plant the companions near the edge of the raised bed. The plan for bed #2 is tomatoes with collard greens, parsley, thyme, sweet peppers, hot peppers, asparagus and some scattered marigolds. Stay tuned for updates from our little urban organic farm and please shareany of your organic gardening tips and or experiences.

Coming Soon: Tulsa Organic Gardening Workshop!
