There can be some confusing information about seeds when choosing to plant a garden. Who would have ever thought there could be so much strong opinion and controversy surrounding the kind of seeds we plant in our gardens! If you’ve shopped for seeds, you may have noticed several terms related to the type and origin of the seeds. These include “heirloom”, “open-pollinated”, “organic”, “hybrid”, and “bio-dynamic”. You might even find some more terms in your shopping!
So what do each of these mean and how do they affect you and your gardening? Let us explain…
Hybrid seeds are those that are derived in the labs of universities or large multi-national corporations. In nature, seed varieties emerge as plants naturally pollinate and the DNA of separate species combine to produce a new species that combine the two. Hybrid seeds are those where that process is purposefully performed in a lab, skipping all the happenstance of nature and replacing it with careful, calculated measures intended to produce a desired result. Furthermore, Hybrid seeds are often created by combining genetic material from species that would not typically combine in nature. This is done to create plants with more favorable characteristics such as color, growing season length, taste, disease resistance, pest resistance, etc. Because this process occurs in a lab, the typical hybrid result – once grown, is unable to reproduce in kind. Therefore, if one were to keep the seeds of a hybrid variety and plant that seed, the result would not be the same as the parent, but of one of the original contributors of the genetic material of the hybrid seed. This is if the seed grows at all. Oftentimes, these are sterile, or have been “programmed” by the producers to not be able to reproduce.
GMO or Genetically Modified Organism
GMO seeds are those that have been engineered in a lab in such a way that genetic material is modified to produce a certain result. It would be fair to say that all GMO seeds are hybrid seeds, but not all hybrid seeds are GMO. In some cases, the genetic modifications simply mimic nature’s process but in a matter of weeks rather than millennia. Other GMO seeds are far more concerning and at times combine even non-plant genetic material with plant material to produce “super plants” that are resistant to pests and diseases and in some cases even produce their own pesticide! GMO seeds are hybrid and therefore cannot reproduce in kind. It is this family’s opinion that many GMO seeds should be avoided because of the “frankenseed” nature of them. These seeds may contain genetic material that would not normally be found in foods consumed by humans.
Heirloom seeds are simply seeds that are not mass-produced or engineered by large multi-national corporations, but rather come from the slower, manual process of individuals and families preserving the seeds of their best crops over time. . These seeds have been chosen from seasonal crops over many years or decades because of their unique and positive attributes. Technically, these seeds are not necessarily “open-pollinated” because a farmer of gardener could have manually pollinated their plants in a greenhouse or field for the desired result. Nevertheless, heirloom seeds were produced under circumstances that are harmonious with the natural order of the plant world.
Open-pollinated means that the plant has naturally pollinated in nature without human interruption in a lab. These are varieties that emerged by chance “as the wind blew” genetic material from one variety to another.
Organic seeds are those that were grown under organic growing conditions and have met the requirements for considering seeds to be certifiably organic. This usually means that the seeds were produced in an environment free of harmful pesticides or chemicals. Some would debate the impact this has on seeds themselves since the resulting plant would not necessarily be effected by the environment in which it’s parent was created. However, others would argue that the DNA of such plants could be damaged or unfavorable altered by being produced under such conditions. In general organic seeds are non-GMO and usually non-hybrid but open-pollinated varieties as well. If you plant these seeds, keep the resulting plant’s seed and re-plant it, you’ll get the same variety of plant. It doesn’t make your plant or garden “organic” all by itself . You’d still have to maintain organic conditions and processes to do so. That’s the topic for another blog – not this one 🙂
According the wikipedia.. Biodynamic agriculture…
“is a method of organic farming that treats farms as unified and individual organisms, emphasizing balancing the holistic development and interrelationship of the soil, plants and animals as a self-nourishing system without external inputs insofar as this is possible given the loss of nutrients due to the export of food. As in other forms of organic agriculture, artificial fertilizers and toxic pesticides and herbicides are strictly avoided.“
Biodynamic seeds are those that were created under such conditions and/or are intended for those wishing to plant the seeds under such conditions. Usually, this means that the seeds have been certified to be Biodynamic by organizations that define and maintain the standards for such. Most gardeners will not need to concern themselves with using certified biodynamic seeds unless they’re looking to start or maintain a certified biodynamic garden. This is not the interest of the average gardener, but usually a commercial pursuit.
Which is best to use?
We’ve been asked this question plenty of times. There’s no single answer to this question. As a family, we endeavor to use organic, heirloom, open-pollinated seeds. We do so because we want seeds that were not created in a lab by those driven by profits. We also want to be able to save seeds from year to year in order to maintain a sustainable food production system. However, doing this carries some risk. In general, hybrid seeds are often going to produce higher yields and more resistance to pests and disease than most open-pollinated varieties.
Growing food can be similar to investing in the stock market, some (like us) want a balanced “portfolio” of produce that maximizes reward and minimizes risk. Therefore, because we try to grow large volumes of our own food, a portion of our planting is often hybrid seed. We still try to avoid most GMO seeds. We choose this mix (at the moment) in order to get more return on our labors and less risk of loss. Were we to plant all open-pollinated varieties, or even single varieties of hybrid seeds, we’d be vulnerable to loss if a pest or weather pattern wreaked havoc on our crop. However, our “emergency” seed supplies are entirely open-pollinated should we ever need to use them. No matter what you plant, consider planting a variety of the same fruit or vegetable. This minimizes risk and can also provide more enjoyable result.
People garden for a number or reasons. The choice of what seed to grow should be based on the reasons one gardens, the desired outcome, and the convictions of the gardener. We garden to grow our own sustainable food. We also don’t care for the immoral and deceitful business practices of some of the companies who produce hybrid and GMO seeds. We choose what we choose for our environment. At the end of the day, you must make your choices based on your needs. Take the time to learn more about the seeds you buy no matter what kind you decide to use. By doing so, you’ll become a healthier, wiser, and better gardener.
