lettuce washing Cindy--BLOGOnce you have gotten quite good at producing food for your table, it is natural to think of providing for others. You could casually share with your neighbors and the local food bank, but many want to take it further and exchange their extra veggies for cash. If that is where your thoughts have been leading you, I would like to offer some things for you to carefully consider before becoming a market gardener. There is a big difference between doing what you love when you have the time and turning doing what you love into a business. During my time as a market grower I grew and sold a lot of lettuce. This photo shows me washing it for a restaurant delivery.

On January 29 I gave the presentation Scaling Up from Homestead to Market Garden at the Virginia Biological Farming Conference. It was well received and people who heard me speak approached me that evening and the next day to thank me for the presentation. Those who had already been selling said that my points hit home. I became an organic gardener so that I would have a healthy family. In order to also have a healthy community I became a market gardener in 1992 and sold to area restaurants. The farmers market network was not yet established at that time. In 1997-98 I had a small CSA in addition to the restaurant sales and in 1999 I was a founding farmer at our local farmers market. I left selling produce and eggs for others after the 2001 season to concentrate on teaching and researching so that I could put more knowledgeable consumers and producers at the markets.

Selling to others on a regular basis highlights the need for good record keeping. You need to plan for how much to grow and to plan for how much money it will bring to your business. No matter how good you are at growing some crops, such as broccoli and cabbage, the income from the same amount of other crops, such as specialty lettuce mixes, will exceed it every time. If you have already been a home gardener and have kept some records of your yields you will be able to anticipate how much you can produce from the space you have. Keep in mind, however, that if you have to break new ground for this endeavor, it may not be as productive as the garden you have been building the soil in for years. Some crops might surprise you. Onions turned out to be a good crop, as well as potatoes, winter squash and garlic—all crops that are not as labor intensive as lettuce.

You need to know what your crops will sell for before you even grow them. Notice what they are being sold for in area grocery stores and farmers markets. Start now and make a chart of the stores and markets in your area with a list of vegetables you might want to sell. Record the prices for them each week throughout the year, noting if they are sold by the piece, pound, bunch, etc. If by the piece, how many pieces make a pound? If by the bunch, how many items make a bunch and how heavy is it? Also record the origin of each crop. This list will be invaluable to you as you move forward with your plans.

Cindy's booth at 17th street--BLOG

Potatoes in wooden boxes were sold by the pound. Small potatoes in pasteboard containers were sold by container.

Although prices might fluctuate in the greater marketplace, I decided on a price that was fair for both myself and for my customers for each crop and kept it the same throughout the season. That said, there are a number of things you could do to vary the price. If you have an abundance of something, you could offer a larger quantity of seconds at a cheaper price per pound. I sorted my potatoes and displayed the smaller ones in pint and quart containers at a higher price per pound than the larger potatoes that were sold by the pound. The price displayed for the containers was by the container size, not by the pound. Nevertheless, the prices remained the same for the abundant seconds (cucumbers), the pints and quarts of potatoes, and everything else for the duration of that season.

Know your produce. People often comment on how much more expensive the colored peppers are in the grocery store compared to the green ones. Well, you need to leave the green peppers on the plant for a few additional weeks to ripen to red, yellow, or orange and anything can happen during that time. I priced my colored peppers at twice as much per pound as the green ones and had no complaints. Besides the prices, you need to know the nutritional value of everything you have and what to do with it in the kitchen. The more information you can pass on to the buyers, the more sales you will make.

I sold a limited variety of produce to the restaurants; primarily leaf and romaine lettuce, tomatoes, peppers, and onions and the chefs did not need me to suggest what to do with it. For the farmers market I needed a larger variety of things for my booth and my customers welcomed my suggestions. The greater population has gotten away from cooking from scratch at home and need some instruction as they move back to that. If you package all the ingredients for salsa, for example, plus the recipe, many are more likely to try it. Packaging all the colors of the peppers you have together will entice your customers to buy the package, rather than just the one or two peppers that they had in mind.

Your passion and enthusiasm will go a long way to making sales, but keep in mind that you need to tend to your family first—and to your soil. If you feel you can grow more than you alrFeed the soileady do, maybe it is time to expand what you are growing for your own table, rather than grow for others. How much of your staple crops, such as potatoes, sweet potatoes, onions, garlic, and grains do you grow? Are you growing enough cover crops to feed back the soil and provide all your own compost?

The first DVD I produced was Cover Crops and Compost Crops IN Your Garden and I was excited that I could show people how to manage cover crops in their gardens with hand tools. I knew it would be a tremendous help to small scale market gardeners—those gardeners moving from growing for their family to growing for others. The garden plan DVD followed which shows how to put together a notebook with your complete plan. I wanted gardeners to have a good foundation to help them plan to feed their families and others. Through my teaching I met folks who were ready to jump into growing for the markets with little experience of getting their hands dirty, let alone an understanding of what is going on in the soil when things grow and in our bodies when we eat the food. By the way, you will get dirty, sweaty, and tired. So tired that you will fall into bed at night thoroughly exhausted, only to get back up early in the morning to do it all again. It is not an occupation for the fainthearted.

I want gardeners to understand all of that before they ramp up to feed others. I expanded on what was in the DVDs when I wrote Grow a Sustainable Diet. It includes an additional worksheet (How Much to Grow), and information on nutrition, food processing and storage, garden washing stations, sheds, fences, and more on garden rotations with cover crops. With that book and the DVDs it is like taking a class from me. No matter how many people you are growing for or how much land you are using, my teaching materials apply. I’ve been talking here about determining how much money you could make, but sometimes the profit in this is not so much about the money you make, but the life you make. You become an integral part of the community around you and you can’t put a dollar value on that.homeplace earth

  • sweet potatoes with peanuts, cowpeas, and collards

    sweet potatoes with peanuts, cowpeas, and collards

This is the fourth year, of the past five, that I’ve eaten only what I’ve grown on the Fridays in Lent. I call these days Homegrown Fridays. I find that it deepens my understanding of what it takes to feed ourselves when I limit myself to only what I’ve grown. By this time of year stored food supplies are diminished and the garden is not quite awake. Our garden and food preservation program has evolved to depend on staple crops that can be stored, rather than canned or frozen. Although I did do a little canning this year, most of the things that couldn’t be stored properly to keep were dried in our solar food dryers.

In the photo you will see one of our Homegrown Friday dinners. It consisted of cowpeas, sweet potatoes, peanuts, and collards fresh from the garden. I often try new things on these days and that day I boiled peanuts. We (my husband and I) decided that eating them raw or roasted was our preference. I depended a lot on peanuts at lunchtime this year. Maybe it was because I seemed to be extra busy on these days. I’d grab some peanuts while sweet potatoes were cooking for lunch. My peanut harvest had picked up in 2012 when I planted some after Austrian winter peas in the rotation. The previous year I had peanuts in a bed following onions and garlic. At harvest time there was a definite difference in the yield in the onion half of the bed compared to the garlic half. Winter peas were the winter cover crop preceding the onion sets that had been planted in the spring. I was pretty sure that the increased peanut yield was due to the winter pea cover crop and not the onions. In 2012 I planted one bed of peanuts after winter peas and one in a bed that had had garlic, onions, and kale. The onions were multipliers and had been there with the garlic and kale since the previous fall. The yield following the Austrian winter peas was three times the one following the alliums and kale.

roasted carrots and beets with black walnut oil

I had a great carrot harvest this winter. You can read about it in my post on Winter Carrots. I also had beets in the garden through the winter. The black walnuts yielded in 2012 so I shelled some and made some oil to put on the carrots and beets when I roasted them. Shelling the walnuts and pressing oil took a long time. I wouldn’t want to depend on that for my cooking oil. Frying locally grown bacon and saving the fat for cooking is a lot easier, but that wasn’t an option for these Fridays, since I hadn’t raised the pig. The roasted carrots and beets were delicious.

Soup made from dried ingredients is always on the menu during this time. One soup I made had no dried ingredients. It was made from carrots, butternut squash, and garlic. I cut them up and roasted them—no oil that day. Then I added water and simmered the cut up, roasted vegetables for about 20 minutes. It all went in the blender and resulted in what you see in this third picture. It was good, but a little bit of dairy added—sour cream, yogurt, or milk—would have been nice. Onions would have been a good addition, but I was down to my dried onions and they were in short supply.

butternut squash, carrot, and garlic soup

Dried onions went into bean burgers using the same recipe as I did in 2012. Our staples for these meals from stored crops were sweet potatoes, peanuts, cowpeas, garlic, sorghum (for flour) and corn (for cornmeal). Fresh from the garden came collards, kale, carrots, and beets. I ground Bloody Butcher corn to make cornmeal mush for breakfast. We have chickens, so we have eggs. I use an egg or two occasionally on Homegrown Fridays, but not much because I don’t grow all the feed for the chickens. Since some of their nutrition comes from our property, an occasional egg is included. Dried tomatoes were important for sauce and other dried vegetables and herbs provided variety in our meals. I’ve already written about our new tea ingredient—Red Thai Roselle Hibiscus. With such a great honey harvest last year we could sweeten our cornmeal mush. Unfortunately, our two beehives didn’t make it through the winter, so I’ll be looking for new bees this year. We had mead made from our honey and grapes, and popcorn cooked without oil.

Observing Homegrown Fridays at this time of year makes me more determined to work out my vole problem with the potatoes to make sure I have enough to last through the winter. I’m also acutely aware that I need to up my wheat harvest. I had an interesting conversation with Eli Rogosa of the Heritage Wheat Conservancy in January while I was preparing an article for Mother Earth News that will appear in the June/July 2013 issue. Eli filled me in on heritage wheat and how to grow it. A chart with her recommended varieties for each region of the U.S. will appear in the article. A chart with crops I’ve mentioned here and varieties recommended for each region will also be included in the article. You will be interested in that article if you want to grow staple crops for your meals.

If you have done any of this, even in a small way, I welcome your comments. It is in sharing, both information and food, that we will move forward on this journey.  Homeplace Earth

potatoes and sweet potatoes-BLOGIn my last post I wrote about how many more calories you could get if you grew beans and corn out and harvested the dried seeds. If you really wanted to grow a lot of calories in a small space, however, you would take a look at potatoes. The low Biointensive yield shown in the Master Charts of How To Grow More Vegetables (HTGMV) by John Jeavons is 100 pounds per 100 ft². There is an average of 349 calories per pound in potatoes—a little more in russets and less in white potatoes, with red-skinned spuds in the middle. If you were really hard-core in growing your calories, I suppose you would grow the russets at 358 calories per pound rather than the whites at 318, but I don’t care for the russet varieties as much as the others. A yield of 100 pounds, which is the best yield I’ve had, would give you 34,900 calories per 100 ft² bed. Comparing it to the corn that I talked about in that last post, with flour corn at 18,216, potatoes would give you 1.9 times the calories. Looking at the beans, with dried beans at 6,152 calories per 100 ft², growing potatoes would give you 5.7 times the calories in the same space.

In order to get all your calories from potatoes, however, you would have to eat many more pounds of potatoes than either beans or corn. To reach 2,000 calories per day, you would need to eat 5.7 pounds of potatoes, 1.2 pounds of flour corn, or 1.3 pounds of dried beans. Your calorie requirements might even be more than that, depending upon your age, sex, and lifestyle. The weight of the corn and beans is the dried weight. When considering the eating, multiply by 3 for the cooked weight, unless it is made into bread and tortillas, then multiply by 2. Hopefully your diet will be more diverse that just potatoes, corn, or beans, but this is how they would compare.

A man once told me that in survival training in the military, he was told that you could get everything you need from a diet of potatoes and milk. According to nutrition charts, a diet of too many potatoes could be toxic in potassium. On the other hand, if you need potassium, eat more potatoes. Having fermented foods, such as sauerkraut, in your diet would help rid your body of toxins. I think it was in the book Nutrition and Physical Degeneration by Weston A. Price that I read that the people he met in the mountains of Peru ate mostly potatoes dipped in a “gravy” of kaolin clay. The clay would have helped rid the body of toxins. It depends on the soil, climate conditions, and how it is grown, whether a food has certain nutrients or toxins in it. Studying indigenous diets is important if you want to grow all your own food. Our culture has lost some of the practices that were important in bringing food to the table. Sometimes they are the key we need to be successful in our endeavors.

Sweet potatoes are another good calorie crop. They might yield a little less per bed, but have a little more calories per pound. At the low biointensive yield that would mean 30,750 calories per 100 ft². In HTGMV Jeavons designates crops as area-efficient if they produce significant calories per area and weight-efficient if the amount that needs to be eaten for all one’s calories is 9 pounds/day or less. Of course, potatoes head the list of crops that are both area-efficient and weight-efficient. Other crops on the list besides sweet potatoes are Jerusalem artichokes, garlic, leeks, parsnips, and salsify.  The information about area and weight efficiency for these crops is in HTGMV and is available online at http://www.growbiointensive.org/grow_main.html.

You might not be growing all your food, but putting a hearty meal on the table occasionally that consists of only food you have grown is pretty satisfying. Check out my Homegrown Friday posts to see some of my experiences on that in 2011 and 2012. If you have done something similar, by all means, add a comment and tell us about it.

 It is good to know what to grow and prepare that will fill you up. There are so many factors to consider when planning your diet around what you grow. You want to make sure it is a sustainable diet, so while you are growing crops for high yields in some things, you are also growing crops that will feed back the soil. That’s where the grains come in. They are weight-efficient, but not area-efficient when it comes to calories, but they produce a lot of necessary carbon for your compost making. The beans, also, are weight-efficient and not area-efficient. You could, however, grow pole beans up the corn stalks and that would up your yield of calories per 100 ft². Beans and grains pair well together to provide the necessary amino acids that make up protein. I’ll talk about growing protein in the next post. See you then!

potatoes in basket--BLOGVoles, sometimes called meadow mice, really like potatoes. If you’ve grown potatoes for any amount of time at your place, it’s a good chance the voles have discovered them and moved right on in. Before I grew so many cover crops, I mulched everything with leaves. Voles love the cover of mulch, happily going about their business (of eating potatoes) out of the reach of predators. As much as I loved mulching the potatoes with leaves, or anything else, I had to stop that practice.

It turns out that voles also love living among the grain crops. More than a decade ago I gave up the leaves in favor of cover crops. I’ve been doing some great soil building and the voles appreciate every bit, living among the roots of the grains while they’re growing and when the roots are decomposing in the beds. I’ve changed up the preceding cover crop for potatoes, first with Austrian winter peas and now with oilseed radish. The winter peas were wonderful, leaving the bed friable and able to be worked by April 1, pulling out the green pea plants for the compost pile, but I still had vole problems. I was betting on the oilseed radish. After all, it’s a brassicus and potatoes and the cabbage family are supposed to be friends. Voles also love radish and their holes were evident through the winter where they’d feasted. One advantage of that is that I set traps and caught a few before the potatoes went in. 

I figure maybe I’m supposed to have vole problems, so that I can work on balancing that part of the ecosystem and give you some advice. This year I decided to address the vole problem head on. I scoured the Internet for suggestions and came up with a few to try. Adding greensand to the bed should help, said one source. I’m a little short on potash in my garden anyway and so I added greensand to every potato bed. Bury elderberry stems with the potatoes, said another source. Drop in some crushed oyster shells when you plant, urged my friend. Crushed oyster shells are something you can buy by the bag and are often used as a calcium supplement to feed to chickens. I planted potatoes six different ways to test all the ideas.

potatoes with vole traps-BLOG

mousetraps are under the plastic pots to trap voles

I already knew that varieties make a difference and that the voles love the yellow fleshed ones more than anything, which is why I had long since given up growing Carolas, my favorite variety.  One year when I did grow Carola potatoes, I also had Butte at one end of the bed. I remember that the voles took out the Carolas and slowed down considerably when they came to the Buttes. My choices for 2012 were Kennebec and Butte. As it turns out, they love Butte more than Kennebec. In my trials, the Kennebec yields were 1.6-2.6 times higher than the Butte yields, with the same planting methods.

Adding elderberry to the plantings interested me, and we have elderberries growing at our place, so that was easy. I put elderberry leaves on top of each potato piece and buried green elderberry stems between the rows. That bed gave me the worst yield of all, resulting in 6.4 lbs/100 ft² for the Buttes and 17.2 lbs/100ft² with the Kennebecs. Remember we make no mistakes, only learning experiences. I learned not to try that again.

potatoes with posts--BLOGOne thing I had an interest in trying is to put a post in each potato spot with a plastic bottle on top to bang around and make vibration. I used old metal posts, the kind used for electric fence, for some of the posts and bamboo for the rest. I cut “wings” in the sides of the plastic bottles and cardboard milk cartons that I put on top of the posts, hoping the “wings” would catch in the wind and vibrate the posts, making conditions uncomfortable for the voles. Even rain should have caused some vibration. I learned that was nothing I need to try again, also. Dealing with the posts and bottles were a lot of bother, anyway. In that bed, I had a row of potatoes down the middle of the bed and I hilled around each one. On one side I set out cabbage when the potatoes were planted. The other side had snap beans, planted after some hilling had been done to the potatoes. Another year I had interplanted potatoes and cabbage and the voles took out the potatoes. Interplanting potatoes and brassicus is officially off my to-do list.

Oyster shells seemed like a logical thing to do, reasoning that voles don’t like the rough surface, but I had tried that before. If it had worked as well as I’d hoped, I’d still be doing it. Besides, my soil didn’t need more calcium. However, my friend said he had good luck with that and urged me to try it again. I did, putting a handful of crushed oyster shells in with each potato piece, then soil, then shells, then topping with soil. Only Buttes were planted in that bed with a yield of 24 lbs/100 ft².  Oyster shells are officially off the list of things to do again, also.

I built a new 4’ x 8’ coldframe this spring. I dug everything out to about 15” and put ½’ hardware cloth in the bottom. Then I built the sides with dry-stacked solid cement blocks, topping that with a wood coldframe, right out of Eliot Coleman’s Four Season Harvest. Although I needed it to grow seedlings, I wanted to first try it as a potato planter. I only had Kennebecs in there for a yield of 43 lbs/100 ft².  I still found vole tunnels in this planting. The voles could have crawled in over the top (an edge sticking out from the coldframe all around might have prevented that) or may have gotten through a crack where the cement blocks may have shifted. Still, I had potatoes. Things were looking up.

potatoes in brick planter--BLOGIn one bed, I tried a variety of things. I buried large black plastic pots with the bottoms cut out, each with 2 potatoes;  2’ high circles of ½” hardware cloth dug into the ground about 10”, each with 3 potatoes; and potatoes planted loose in between these barriers. The Butte half of that bed yielded 35 lbs/100 ft² and the Kennebec yield was 71.8 lbs/100 ft².  At the end of that bed I had built a planter, laying hardware cloth on the ground and making a surround 3 bricks high, filling it with soil. Into that I put 4 potatoes. Granted, it was a very small area, but the yield was 98 lbs/100 ft²! After fighting the voles for years, friends of mine had done something similar to grow their sweet potatoes in, with success. I would have thought the voles would just climb over the bricks to get in, but maybe they like to stay close to the ground.  

I usually space my potatoes equidistant, every 12”, but with the vole problems, I thought I might be making it too easy for them to go from one to the other. This year, in one 4’ x 20’ bed I put just two rows of 20 potatoes in each row, hilling each plant separately. The Butte half yielded 18.25 lbs/100 ft² and the Kennebec half gave me 30.25 lbs/100 ft². Comparing the Kennebecs in the hilled rows and the ones in the brick planter, 30 pounds is a lot less than 98 lbs. per 100 ft², but just about the same yield per plant. I could increase the yield in that bed with hilled rows if I interplanted something after the potatoes were hilled for the last time and if I was more aggressive about trapping voles early. The interplanted crop would have to be ready to come out with the potatoes.  

Our daughter, Betsy, Lightfoot Gardening Coach, and I have been exchanging notes on potatoes. This is her second year in a garden that she carved out of a field, double-digging the beds when she started. She had planted oats and oilseed radish in her beds preceding potatoes. Since we had such a mild winter, she had to chop the oats in and let that crop compost in place. She pulled the radishes for the compost pile. In “normal” years, if there is such a thing, those crops would have winter killed. She planted Elba potatoes and in the oats bed, with the potatoes planted intensively with offset spacing, she harvested 107 lbs/100 ft².  In the radish bed she planted two long rows and hilled each row 3 times. Her yield there was 90 lbs/100 ft². Planting it that way, she used only about half the potatoes and came close to the same yield. She also noticed that the hilled Elbas were larger than those planted intensively. She planted Red Norlands in a bed that had oilseed radish over the winter. It was treated the same way as the hilled Elbas. There was lots of vole damage, producing a yield of 50 lbs/100 ft². She had noticed vole damage during the winter in her radish cover crop and had worried about this year’s potato harvest. She did okay, with bushels of potatoes for her larder. 

One good thing about keeping records is that it helps in planning for next year. I will continue working with Kennebec potatoes and will compare them to Betsy’s Elbas. I might grow a radish cover crop and trap the voles through the winter, something I should have worked more on this year. I’m going to be looking at different preceding cover crops and planting in hilled rows with space for possible interplanting on the sides. Although I don’t like to do much cultivation, I think regular cultivation and hilling helps deter the voles. Hoping to develop an ecosystem that makes the voles stay away voluntarily, I’ve been adding daffodils to the perimeters of some beds (have yet to see that as effective) and have added castor plants to the garden. In the end, it will be everything together that determines success—variety, planting and cultivation, soil fertility, weather, etc. Wishing you success in your potato endeavors. Do you have any potato/vole experiences you would like to share?
