giveaway: learning to save seed, with seed savers exchange’s tim johnson

copyright seed savers exchange 2DOES YOUR GARDEN PLAN include an end game of seed saving–of letting favorite edibles produce not just a delicious harvest, but also the start of next year’s plantings, and of generations beyond?

“The Seed Garden: The Art and Practice of Seed Saving,” just released by Seed Savers Exchange in collaboration with Organic Seed Alliance, provides a comprehensive overview of seed saving–both art and science. It includes detailed how-to’s on more than 75 crops: how to grow them with a seed crop in mind, right through to harvest, cleaning and successful storage. (Enter to win a copy in the comments box at the very bottom of the page.)

One of the book’s expert contributors, Dr. Timothy Johnson, head of preservation and also the seed bank manager for Seed Savers in Decorah, Iowa, joined me on the May 4, 2015 edition of my public-radio show and podcast to help us start our gardens with seed saving in mind.

Tim has worked for more than a decade in the field of conservation, helping to preserve wild and domesticated plant species. Now, with a fulltime staff of 12, he maintains the Seed Savers’ plant collection—more than 20,000 different varieties in about 100 species, primarily edibles. (Part of SSE’s Heritage Farm is in the photo below.)

Read along as you listen to the May 4, 2015 edition of my public-radio show and podcast using the player below, as we learn what seeds to try to save, and how, as backyard gardeners. You can subscribe to all future editions on iTunes or Stitcher (and browse my archive of podcasts here).

read/listen: seed saving,

a q&a with dr. tim johnson

 

 

TimQ. Despite your expertise in managing the Seed Savers collection, how would you rate yourself at home as a seed saver?

A. As a seed saver, I consider myself to be a novice. And I’m also a pretty lazy seed saver—I’m opportunistic. If I happen to see something that I really like around the farm, I might save a fruit of a tomato. Or if I grow something in my garden and just absolutely loved it, I might save one or two fruits. I don’t have any family heirlooms; I’m pretty low-intensity. If I lose the seed, that’s OK—that’s kind of my style.

Q. Today we’ll help people take it a notch farther than that [laughter]—but without getting too uptight. And I think that’s the key, because the plants want to make seed, given the right conditions…

A. …and with the book, “The Seed Garden,” we really address that whole range of intensity, from people who have never saved seed before and might just be looking to save seed from one tomato fruit, all the way up to people who have things that they are really concerned about saving for the longterm.

The book provides lots of instructions and suggestions based on what people’s goals are—so it can be just as easy as the way that I do it, or it can be much more intensive.

Q. On the back of the book, printed on a dreamy photo of maybe dried garlic chives with the black seeds spilling out of the seedheads, I love this inspiring statement:

“The simple act of saving seeds carries forward centuries of work by humans to cultivate plants that sustain and inspire us.”

That says it all: There is really awe, and history, and this co-evolution—we and the plants have evolved together, them helping sustain us.

A. At the very beginning of modern human history is saving seeds. Those first saved seeds really freed up our ancestors and made their lives a lot more convenient and predictable.

Q. The book is in collaboration with Organic Seed Alliance—good friends—and there is so much wisdom between the two entities, a formidable collaboration.

A. The go-ahead for the book really happened in 2010. “Seed to Seed” was first published in 1991 by Seed Savers—really the first book on seed saving. It was updated in 2002. Our board of directors was rumbling that it was time for an update, and in 2010 they charged us to do it. In 2011 we contracted with OSA to help us, because most of the knowledge and published information is about seed production at more of a commercial scale.

Q. Yes, agricultural or commercial scale—and it’s hard sometimes to get it down to the backyard level, or even small farm or market-grower level.

A. We spent a lot of time working on that, trying to extrapolate backwards, drawing on all of our wisdom and expert friends to try to figure out what really makes sense for gardeners.

Q. We might not have thresher or specialized equipment in our homes.

A. And even things like population sizes, where it might be for a commercial seed producer more about how large of a population you need to get a good harvest, more than how many plants do you need to produce good seed.

Q. I loved the section of the book that talked about if you’re new or newish to seed saving, here are some easy crops that you can save. The first piece of guidance it offers is that one should start with “annuals that self-pollinate,” because those are the easiest candidates.

A. The book is really divided into three sections. The front section is a lot of theory and biology, and general information about seed saving and techniques. Section 2 is more instruction about specific crops and how to grow those for seed production. The third section is the short notes: If you’re already a master seed saver and you’re just curious about isolation distances, you can jump right into Section 3 and look it up.

With any of the crop types—for example peas, which are a great beginner crop—the first thing in the book is a little popout of short notes, suggestions on what you’re going to need for spacing, population size, and a little biology just to help orient people.

sugar magnolia purple snap pea flowerQ. Speaking of peas: As I said, “annuals that self-pollinate” are recommended as easiest, but you think: “What does that mean?” But you can look at some flowers’ structure and how open they are to cross-pollination—what they look like—and maybe get some clues to whether they self-pollinate or not. 

A. That’s right. With peas, for example, one of the petals is modified into what’s called a keel—just like the keel of a boat, and it looks like that. That holds all of the reproductive parts inside the flower—it closes them in.

That means with peas, there is very little chance that an insect is going to get in there and pick up some pollen, and then fly away and pollinate another flower. Most of what happens with peas is that they’re actually pollinated very early, even before the flower is fully open.

Q. So peas are a good one to start saving. And beans, another legume?

A. Beans are also a good beginner crop.

Q. Another great thing about peas and beans: They create little packages of seed for you—the pods.

A. And it’s also such a familiar crop. If we’re talking about dried peas and dried beans, then producing your food crop is producing your seed crop. Just saving back a couple of seeds—not eating everything but showing a little restraint—means that you’re a seed saver, as long as you’ve taken some precautions to isolate one variety from the other varieties with some crops.

lettuce going to seedQ. Lettuce is another recommended beginner seed to save. Often if it gets too hot, or your lettuce is old, whoosh! Up comes the yellowish flowers, and it gets bitter and bolts (above).

A. Lettuce is another crop that is almost entirely selfing…

Q. …Self-pollinating?

A. Yes, and that means that having even just one plant, allowing one plant to bolt, that you can produce lots of seeds, enough for a couple of years worth of lettuce harvest.

And the other nice thing about lettuce—and peas and beans, too—is the [relatively small] distance that’s needed between varieties to prevent them crossing with each other (because the goal with seed saving is to produce seed that’s true to type: that looks like the parents). With lettuce, unless you’re touching flowers together, they will be selfing.

Q. Talking about the lettuce bolting reminds me: Sometimes that happens, and you think, “Oh, I should save that seed,” but you can get a little misled there: You don’t want to save seed from the earliest-bolting lettuce in the garden, because being quick-to-bolt is not a favorable trait, right?

A. That’s exactly right. A couple of other crops will do that, too: spinach, for instance. There is some variability, and you don’t want those early ones, because they’ll pass on that trait. Suddenly your next generation, your next grow-out of that seed, will bolt even earlier in the year for you.

Q. We have to be the seed selectors, to manage with our human hand and our eyes and our observation. Like the book says: It’s the “art and practice” of seed saving, and we have to use our human touch and our inferences, and draw from careful observations.

A. The term we use in the book is rogueing, which is basically looking for plants that do not meet the stereotype, and removing them. They’re not the right color, they’re not the right shape; they’re flowering too early; they’re the wrong taste. Just to make sure that the variety maintains its ideal characteristics.

Q. A friend who is a seed farmer at Turtle Tree, the biodynamic seed company near me, says she starts her seed-selection process from the minute she sows the seed. She even “rogues out” any tiny seeds in the packet that don’t look as robust as the others.

A. When we’re working with our collection, we’re pretty rigorous, too. We’re looking for the color of the seedling; we’re looking for vigor in those seedlings. But at home you can decide how involved you want to be.

DSC_7679_master_webA good example: tomatoes. They are another fairly easy crop, and the majority of the time they are self-pollinating. Occasionally you’ll get a bee in there that will do a little cross-pollination.

If you’re lazy like me, and not too particular and just want tomatoes, maybe that’s OK to have a couple in there that don’t look exactly like the last generation.

Q. And as a home gardener, you’re not going to sell your seed; your reputation isn’t being eroded if you have a few oddballs in the next generation. [Laughter.]

We’ve said that peas and beans, lettuce, tomatoes are easy beginner crops for seed saving. I think cucumbers and melons are easy for beginners, too. 

A. With cucumbers, melons and winter squash, you are relying on the plant to tell you when the seeds are ready. When they’re at the eating stage, the seeds are also fully mature.

It’s not that way with zucchini—with your summer squash. When they are fully mature they’re not that appetizing; they’re gigantic, and hard.

DSC_5504_webQ. Better as doorstops or bludgeons than as dinner. [Laughter.]

A. That’s exactly right.

Q. That’s such a good point: They’re all related, all cucurbits—but the summer squash is different from winter squash or melons, because the seeds aren’t ready at eating time, when their shells are soft.

A. And you wouldn’t eat them when they are seed-mature.  Cucumbers are like that, also. When you’re pickling your cucumbers, they’re not fully mature; they’re fruit-immature. You need to let some go fully ripe, to the point where you are not going to want to eat them, if you want to save those seeds.

But with melon and winter squash, you can actually have those do double-duty, where you harvest for eating, and you’re also harvesting for seed (if you’ve taken some precautions to make sure that the variety has only been pollinated by individuals of that same variety).

Q. I was interested to see that okra—with its beautiful, ornamental flowers and pods—was on the easy list.

A. It’s another crop that will readily self-pollinate. Okra flowers will also out-cross, so you have to take some precautions. But in most regions of the country you don’t have a ton of people growing okra in your neighborhood. So if you’re only growing one okra in your garden, and your neighbors aren’t, you probably don’t have to do anything else but let those pods develop, and dry down, and then harvest the seeds to have seed that’s true to type in the next generation.

Q. If we want to go beyond the beginner crops, to an intermediate-level choice, maybe we try a biennial, like onions.

A. There is a little bit more to know about onions, but it’s still an easy crop. You just have to do a little more planning.

curing onions at seed libraryQ. In my Zone 5B northern garden, a big onion bulb won’t reliably overwinter in the ground—it will rot. So I’d have to lift it, store it very cool, simulating winter, and then replant it and let it go to flower.

A. This is where “The Seed Garden” is really going to help people. How you grow onions really depends where you are in the country, or the world. Onions start to form their bulbs in response to daylength. Whether you’re in the North or South, you might want one that’s longer or shorter in order to get the plant to a suitable size before it starts to bulb. You don’t want it to start bulbing as a seedling. The next step is whether you can overwinter it in the ground or need to get it out of the ground; whether you’re in a region where you get hard enough frost that will kill your bulbs.

And then there are also parts of the country that are so warm that you can’t vernalize onions; you can’t get them ready to flower outside.

Q. Create that simulated winter, you mean? Some places you’re preventing it from freezing, and some places you’re providing the sufficient trigger in terms of cold?

A. Yes, that’s right.

Q. Let’s finish up with some seed-storage basics—because after all, you are in change of the Seed Savers seed bank. [Laughter.]

The ideal conditions are? (And of course you have a state-of-the-art facility there, but I don’t.)

A.  For the home gardener, the general tips are cool and dry. When we store seed cool and dry, we’re actually slowing down the rate of deterioration. Seeds are alive, and they only have so much energy. Cooling them down, drying them out slows down that process.

For people in arid regions, they can probably rely on normal ambient relative humidity to dry the seeds down to a point where they can actually put the seeds in the freezer when they’re dry.

DSC_6535_webQ. But where I am in the Northeast, it’s humid at harvest time—not good.

A. So you’re left with one of two routes: One is that you don’t freeze your seeds; you store them in a refrigerator, or a basement.  Something other than freezing them, because the danger is when they’re too wet, and you freeze them, ice crystals form and it will kill the seed.

The other option is to try and dry the seeds down.  You can do this in a lot of different ways. If you have air conditioning, and the relative humidity in your house is below about 20 percent—you can buy a little relative-humidity gauge at the hardware store; they’re pretty cheap—you might be OK to then put the seeds into the freezer.

You can also try rice; storing the seeds in a breathable bag sealed inside something else with some dried-out rice.  You put the rice in the oven first, on a really low temperature, to dry the rice out. The rice will then actually pull water out of the seeds.

Q. It’s a safer, more organic (so to speak) version of silica gel?

A. Yes, and then you can safely put that seed into the freezer. If you’re not sure, but you want to try it, here’s an easy thing to do:

Put some in your refrigerator, or your basement, because you know that will be fine, and put some in the freezer. Just try it. If it lives in the freezer, you might be OK doing that regularly; if not, you might have to take some more precautions, or rely on above-freezing storage.

  1. JessB says:

    I save zinnia and marigold seed. I’ve saved tomato and lettuce before as well but they take more work than flowers and with kids, time is everything! Love SSE, I’m a proud mbr!

  2. Shelley says:

    This April, i started my tomatoes seeds from my first seed saving attempt last year. (YAY!) All varieties germinated (luckily) but i did nothing special… this book should teach me a thing or two!

    The part of your interview about the zucchini made me laugh. I think of the competition my father and i used to have when we grew zucchinis. We always grew the largest “caveman clubs” you’ve ever seen to compare them and you know what? They sucked. lol You couldn’t eat them, they were awful and seedy (little did i realize i just grew my seeds for the following year). I know now to harvest them a lot earlier to be able to enjoy them but it just proves bigger is NOT always better.

    Great post as always!

  3. Julia Hofley says:

    Hi Margaret!
    I plan on saving and sharing more of the variegated Kiss-Me-Over-the-Garden-Gate as I once was able to buy it at a local garden center, but have heard the seed is not available anymore. It’s a show stopper at the end of the season. All of it from one plant about 6 years old now.

  4. Jeanmarie Morelli says:

    I bought a copy of the long-awaited Seed Garden and gave it as a birthday gift to a friend who has saved seed for 35 years. My seed saving has been simple so far, just flowers, lettuce, and parsley. This year I hope to save seeds of dried beans. Just getting the vegetable garden in the ground now and want to learn more. Thanks.

  5. Anita Leimbach says:

    I have already planted some seeds I saved from last year: cilantro, Tom Thumb lettuce, and He-Shi-Ko onions. I plan on saving squash seeds (Lakota, and Mormon Squash) this year.

  6. lynn novick says:

    I’ve only saved Marigold and Milkweed seeds because I do not have good conditions for starting seeds indoors yet and I live in Zone 4B. I also saved some Cosmos from a friend’s garden. I love saving seeds but have to research how each time I try.
    I love your newsletter! Thank you.

  7. Jean Yowpa says:

    I would like to save seeds from my Heirloom tomatoes for the first time.
    I am growing for the 1st time, Amish Paste, Black Krim, Celebrity, Cherokee and Red Brandywine.
    I grew tomatoes indoors from seed my first time this past winter/spring.
    I am excited to try saving tomato seeds.
    Thank you for the opportunity.

  8. Stephanie says:

    Last year I let some kale go to seed and saved the seed by hanging the dead plants in my shed where I hang my garlic to dry. I’ll plant the seeds this year and see if they’re viable. If so, it’s a very easy way of never having to buy kale seeds again, because each plant produces a lot of seeds.

  9. Schleicher Mary says:

    I’m a long time gardener. Only during the last decade has seed saving become a part of gardening. Now it’s a compulsion just as much as weeding. I saved scarlet runner beans, delicate squash, hubbard squash, snow peas, english peas, potatoes and garlic. And the seed saving brought me to a point where a neighborhood garden was not enough. And after much yearning and moaning I convinced my husband to take a leap with me to acreage.

    We bought a five acre “horse pasture” a three years ago. I loved the area, but felt the land was barren. My husband loved the area, his new, huge shop and didn’t want to spend his days off mowing acres. After the garden area was built I found myself unsatisfied as I looked about at all the fallow land. My vegetable garden wasn’t going to be enough. My husbands face was painted with shock and horror as I announced one day that I was going to return our land to the wild. But, that didn’t last long because in the process of returning tired pasture to life we have found renewed life.

    First planted a few small nut trees. Next a seasonal pond was made larger, deeper and fed by runoff from house, garage and shop. We were thinking it would be nice for a few fish. I assumed that I’d have buy water plants and feed the fish. Before we were finished deciding what to put where things just started showing up. Frogs, more birds, plants, salamanders, dragonflies etc. There is even a brown fish that somehow arrived. The only thing we did was dig and add some goldfish. Nature added layers of diversity and balance automatically. What we got was more than nice. Water started life’s return.

    I am an avid bird feeder, but decided that it would be better to establish food sources and nesting areas as well. We will not always be here to provide. So, eachy year a new type of tree or two is planted. We also now do not mow anything but a little patch around the house. That was difficult for my husband to adapt to, but when more kinds of “neighbors” appeared. It became right for him. Sharing.

    This got me inspired to grow other food and housing sources for more creatures. This year new fruit and flower trees were added as well as berries bushes. I find and transplant native plants and heavily mixed groupings just seem to take form. It’s not being done according to a plan since we’re learning as we go along. Rather, groupings are inspired by what’s not happening in an area.

    The vegetable garden had to be fenced in, but even so it too has become a part of this campaign. A toad pot, bird feeder, bird bath, flowers, farmer bee box and herbs now gather around the usual plants. I’m hoping that this year the “critters” will help out with the pests and if something is nibbled or pecked I don’t care.

    It was strange last year when we visited a next door neighbor for a pit fire. They were plagued by mosquitoes. Walking home we realized that we didn’t have that problem. Then we saw bats and remembered the swallows that had rented out several bird houses for the season. Add in the bull frogs, toads and miriad birds that are everywhere and bugs become balanced too.

    When I started seed saving gardening somehow became more of a natural cycle. Seed saving has been an intigral part of “giving back to receive” style of life that has developed. Those vegetables that grow well here stay here by my helping the plants to survive the winter via seed saving. It also adds greatly to the amount of diversity and quality I can bring to the table and life in the garden. Learning simple seed saving has also enabled me to save untainted hubbard squash and sunflower seeds to add into winter bird and squirrel food as well.

    Seed saving is not just about a way to save for our future or show the next door neighbor the purple broccoli you grew. Seed saving is about being a part of the cycle of life. Seed saving started us on a journey. Feeling a part of that cyle brought us to understand living is about being part of a natural community. The other lives we live with are neighbors. The more variety the more life. Being a part of a chirping, chattering, buzzing, quacking, barking, croaking community is joy and peace. Having amazing gardens filled with diversity makes it eden.

  10. Bev Cato says:

    In my 15′ X 20′ garden plot I grow several varieties of tomato and squash. I do not save their seeds, knowing the next generation fruit would not be true to the parent. I must admit though that when I have a volunteer the following season, I let it mature out of curiosity and a sort of parenting feeling.

  11. Steph says:

    Yes! I have been learning, by trial and error, to save seed for a few years now. Onions, Okra, Orach Spinach, & Beans have been pretty easy so far. My yard is a test-garden; I keep notes as to what works and what doesn’t. This year, I will be attempting to save seed from several types of heirloom tomatoes. Keeping my fingers crossed, as I won’t know if I have been successful until next summer’s planting! :-)

  12. Beth says:

    Last year I designed a small herb garden and harvested and dried the herbs and saved some of the seeds. My fingers are crossed that the saved seeds will produce new plants this year!

  13. Kathy Moody says:

    I have saved seed before from Blue English Larkspur, and had much success. These plants do not like to be transplanted but grow well from seed. They are truly a magnificent blue color, and
    I will save these to share with friends.

  14. Sheila Lohrie says:

    I’ve been wanting to save seeds for a few years now. I tried to remember how my dad did it, however I was young back then and not paying attention. His second generation flowers were beautiful and his huge vegetable garden to die for. I get disappointed when buying seeds at how many don’t look healthy or do not germinate at all. So this year I definitely want to learn the proper way to preserve them. I saved the seeds from my marigolds last year but it did not work so well. I only have one that has germinated in a indoor pot. Boo Hoo.

  15. C Mahoney says:

    I saved runner bean and purple snake bean seed last year and are waiting to see if they sprout. I regularly gather some nasturtium seed so that I can replant those where I like. My arugula is going to seed and while I will let it self sow, I’m thinking to also collect some seed in case I want to move the bed. I’d like to expand my seed saving, especially for things I’ve found work particularly well in my garden. I suppose I could save fava seed…but I can seem to part with a single bean!

  16. Anjana S says:

    I would love to save seeds have not yet started. I would like to save seeds for some heirloom tomatoes and indian holy basil. Thanks for the give away.

  17. ron says:

    I like to save pumpkin seeds, tomato, flax, lettuce and basil every year… all of these have volunteered before, so I thought saving viable seed would be easy.

  18. Leslie Gossage says:

    I have saved only tomato seeds but would like to try to save more kinds. I have had self-sowing of arugula and tomatillos occur, which both were very welcome freebies. It would be great to save seeds of favorite beans, peas, cucurbits, and greens. Thanks for the great information!

  19. Kathy P says:

    The Seed Saver book would be an informative guide. As an amateur flower and veggie gardener, I look for seeds in everything and everywhere! My husband knows the look on my face when I see a flower and want to pull over to pick seeds on side of road. He’s gotten real good at driving our little fishing boat to the lake’s edge so I can snatched seeds from the bank.
    Some grow, some don’t! Tree seeds have worked well here in Oklahoma. I am fascinated with trying to grow anything from seed.

  20. Gwendolyn Rose says:

    I will be saving the seed from a rainbow chard. It lasted through the winter and is now a year old and starting to bolt. A great producer and hardy.

  21. bett macphee says:

    yes, i save seeds & have done so for many many years. best results with peas, beans, peppers. I also shake the chopped off heads of perennials & annuals over the garden in the fall. wonderful to watch what appears next year. i would love to have this wonderful sounding book, The Seed Garden

  22. priscilla says:

    I have been saving seeds for a couple years. I am mainly an opportunistic seed saver. If there is a dried seed head or pod staring me in the face, I grab it. Last summer I saved a lot of flower seeds (zinnias, gallardia, cosmos, hummingbird vine, love in a puff, sunflower, Echinacea, rudebeckia, etc.). Last summer, I saved tomato seed for the first time using instructions from SSE. This book sounds great!!

  23. Ken Zack says:

    Have never saved seed before, but after hearing the podcast, think I’ll try to save some bean or pea seeds. Thanks!

  24. Kerry says:

    I have saved 4 o’clocks before but I’ve never tried saving vegetable seeds. I think I’ll save some lettuce and spinach seeds this year!
