ICE COLD!




Its like an old sepia toned tin-type photo....
Welcome back to a snow dappled edition of Lost in the Farmer’s Market, this is our first episode of February. Now as you know, these episodes used to be posted on Saturdays hence the actual post date for this would have been February first. Because we’ve got a booth at the Fayetteville farmer’s Market the episodes are released early, so you can see what we’ll have in advance. With that said today’s topic is the first of a two part series defining the terms Genetically Modified Organism and Hybrid. Next week we will cover the terms Heritage, Heirloom and Open Pollenated.

So let’s get started with the term GMO, this is a abbreviation for Genetically Modified Organism. There is a lot of hype about this one and in truth a lot of it is justified. The corporations most mentioned for being involved with these creations act as though they are accountable to no one. Monsanto in particular is willing to do anything to loosen the restraints on its activities to make a buck. But what is a GMO? Well by definition I believe there are five types of GMO, each with a level of risk.

GMO Type I
Type 1 GMOs are genetically altered specifically using their own existing genetics. No foreign genetics are introduced and the goal is to get say a redder tomato or a carrot that has more beta carotene. This would be a much more expensive equal to say open pollination and selection of plants for traits.

Characteristics:
-The individual specimen’s own genes are used.
-Genetic clones are common.
-Pollen cross contamination is noticeable but not a significant risk.
-Low risk.


GMO Type II
Type II GMOs are a lot like Type I in that the selected organism’s own genetics are used. Genes from closely related members of the same family are also used.

Characteristics:
-Genetics from plants in same family, and are generally directly related.
-Original genetics are still being used.
-Pollen cross contamination is a possible problem.
-Intermediate risk.


GMO Type III
Type III GMOs are where the weird science comes in. Type three’s will often have something extra added in. Perhaps making a redder tomato was not enough, now the labs want to make a redder tomato that is perfectly shaped…so they unlock a gene for redness, borrow a gene from another tomato to make the tomato’s skin more lustrous and then they borrow a gene from say an eggplant to make the flesh firmer. Ok so all plants in the example were from the night shade family. The problem is Eggplant and Tomato are highly unlikely to cross in nature so that eggplant gene, would never have crossed so then have a unnatural plant that may manifest unexpected results later on.

Characteristics:
-May use genes from plants in the same family.
-Gene sources may bear unforeseen effects.
-Pollen contamination is likely especially if source genetics are not carefully selected.
-Moderate Risk.


GMO Type IV
Type IV GMOs are where the real problems begin because now the labs want to cross families entirely. They want to sell you a blue rose, so they use a petunia gene to make the rose produce shades of blue otherwise impossible. They want your corn to be pest resistant, so they use a natural pesticide gene from a potato so the corn produces its own pesticide. The list goes on but basically at this level the crossings of genetic material is all impossible in nature so these plants must be lab cultured and then grown on and in theory should be field tested (for 5-10 years which never happens) and FDA trial tested for 20 years (also never happens).

Characteristics:
-Genetics cross plant families.
-Pollen cross contamination is a constant issue.
-Mutation risk is present.
-Potential Acute Toxicity if used as food product.
-Moderate-High Risk.


GMO Type V
The final type of GMO is type V, which refers to the genetic structuring of an organism to do things that otherwise would not be normal in nature. Prime examples are pesticide immune strains of corn which otherwise would not have such protections, another example can be seen with the ‘terminator seeds’.

Characteristics:
-Uses genetic material from differing families of plant.
-May also use genetic material from non-plant species.
-Has high risk of cross-contamination via pollen.
-Has high risk of counter adaptation by ‘weed’ species.
-Can be bred to force financial servitude to company.
-Long term health effects suggested by independent study to be negative.
-High Risk.


The next term to discuss is ‘Hybrid’, which has gotten a bad rap in recent days as it is often lumped in with genetically modified organism as a bad thing. In truth a hybrid is generally any sexual cross between two compatible organisms. If we were talking humans we might call that ‘Mixed’ or for a dog ‘Mutt’. Genetically it’s the same thing, however for the purposes of agriculture it’s really little more than an observation of fact. Hybrid plants are not inherently bad as long as their documentation clearly indicates what plants were crossed to get the resulting offspring. That would be the real curve ball in the term hybrid.  If one crosses two heirlooms they still get a heirloom-hybrid, likewise if one crosses a successful hybrid with an heirloom you still get a hybrid-heirloom of another sort. However if you cross a heirloom with a compatible GMO variety, then you get a GMO-hybrid. In short as long as you can verify the parentage of a species then hybrids are not a problem and in fact are a normal part of agriculture. A good case in point is can be found with some of the more famous herbs as of late.

Mentha x piperita f. citrata ‘Chocolate Mint’ – a clear genetic cross between upwards of three mint types.  Plain old mint was crossed with a hybrid of Pepper mint and Citrus mint and then was selected for scent and flavor.

Basilicum kilimandscharicum x Basilicum ‘Dark Opal’  or Blue African Basil – A genetic cross between Camphor Basil and a cultivated variety of sweet basil.

Ocimum x citriodorum ‘Pesto Purpetuo’ – A flowerless sterile basil expressly intended for use in pesto. It is a cross of sweet basil and a variety of Lemon Basil.

As you can see the term hybrid isn’t so scary as long as you can figure out your plant’s history. You want to seek out clean non-GMO organic certified seeds to verify what you are growing is not coming with an unwanted genetic guest. Due to the size of this topic we will have to continue next week with the terms Heirloom, Heritage and Open pollenated.  With all that covered in detail we move onto the market information for this weekend.

The BL2 mascot is out enjoying the winter splendor.
The Fayetteville City/Farmer’s Market occurs every Saturday from 9:00 AM through 1:00 PM. The market is located at 325 Franklin Street in the parking lot of the Fayetteville Transportation museum. Since we are a year-round operation you can expect there will be fresh foods of some type available at the market and as always yours truly is always prepared with garden advice and great plants. Here is a list of what will be coming to the market this week.

Southward Skies: A northern guide to southern Gardening
This is the second edition of my book, which was published using data compiled from several years of test garden operations. It’s written to aid gardeners of all skill levels in successful garden methods that are targeted for the south east but had proven to be a valued resource for gardens across the weather coast. It’s certainly a good gift for that gardener you know or for yourself if you’d like to have a reliable field guide. The book costs $25.00 and we do take checks for this item, you can even have it signed.

Black Magic Fertilizer
That’s right you’ve heard about it in trials all summer. This specially formulated liquid fertilizer was made and tested at the test gardens using natural ingredients and no chemicals. The result explosive growth, great harvests and of course no environmental side effects! We’re making batches of this stuff to order, at $6.00 per gallon of fertilizer. You can either order it at the market and pick it up the next week or have it delivered to your home in the Fayetteville area for a delivery charge of an additional $2.00.

Fresh Cut Herbs
Bundles of Fresh Rosemary, short stem ($1.00)
Bagged Lavender ($2.00)

House Plants
8x Holiday Cactus ($3.00)

Garden Plants
2x Morris-Heading Cabbage Collards 0.5 gal pot ($3.00)
2x Georgia Collards, 0.5 gal pot ($3.00)
 
So this concludes the first LITFM Episode of February, we came in with snow which as the pictures posted will attest was quite lovely. For note we received 1” of snow, which translates to 0.5” of actual precipitation. I’d say we’re coming into the New Year just right for precipitation. I hope to see some of you down at the market, and as always keep ‘em growing!


It's so cold and quiet all I could hear when I took this picture was the delicate crinkling of the snow falling and the rare sound of a vehicle engine very distant. No aircraft...no music nothing else dared break winters imposed silence. It was glorious!

P.S.

Original Title: "Take Off! To the Great White South!"
 -Author's note:The title came to mind because of the above picture and then we dropped it because it simply sounded wrong.

The Humble Seed




Welcome back to another episode of Lost in the Farmers market; today’s topic is the deconstruction of the often baffling terminology surrounding seeds. The goal of today's post is to hopefully provide you the reader with all the information needed to discern what the heck they are talking about in the seed catalogs you receive every spring. Before I get into talk about seed terminology, I need to do a few special notes regarding people and events that have just occurred.

First off I would like to direct all of you to look up the blog Suburban Hermit of Fayetteville, run by a neighbor of mine just up the road. This guy makes in credible use of concrete bits to make these amazing curved terraces in fact his backyard is quite incredible. It’s a good blog with lots of photos and information. Secondly I would like to thank everyone who attended the Sustainable Neighbors Fermented Foods event on Saturday and thank everyone who stayed or came to join in on the Seed Swap event right after. You guys all of you are truly amazing, the response to the fermented foods event was impressive, Perhaps worth a six-month repeat towards the fall even. The seed swap crew was quite incredible as all sorts of seeds were exchanged and honestly the bulk of them were hardcore organic. Out of this I can now say with certainty what BL2 will be growing this year the plant list for 2013 is now in stone with one addition due to a conversation with Marsha about a certain plant variety and will be posted up here in the next LITFM post. Thank you everyone for participating in the event, it was great to see you all.
As a final note to the mention of the seed swap, I think those who read this blog and are in or near the Fayetteville area ought to sit down and have a crop discussion. I noticed that some of our local sustainable neighbors could grow certain things but not others and thus we may have the beginnings of our own local food network. All we need to do is either take a record of what participants can or cannot be grown and start coordinating crops. If we were able to do that we might have the humble beginnings of a new breed of farmers market. If you are interested feel free to contact me through this blog or through sustainable neighbors. You can also contact the wonderful Marsha Howe through Sustainable neighbors with your thoughts comments or if you want to participate.

With all of that said today I would like to talk to all of you about what a seed is and the terminology surrounding it.

The symbolism of the seed is quite well known as it often is used to represent raw potential, and to a lesser extent a state of plant immortality. From this tiny dry little thing comes a great plant that has equal power to feed (Lettuce), beatify (roses) or be a scourge (poison ivy) or even can do great things to improve the environment (mustard).  We as gardeners spend so much time thinking over what seeds to buy because in that tiny packet there are dozens of little potential plants that can make our corner of the word better.

Like anything else the seed is a living breathing organism with a definite life span and it has needs. Some seeds wont germinate unless certain conditions are met while others practice ally grow on anything (chia pet anyone?). Seeds like plants are illiterate, they can’t read your seed packet, don’t care how they were raised and don’t even know what a book is so their ability to do what is genetically preprogrammed is an product of ongoing evolution. Some plants are utterly reliant on mankind to keep them going as they have somehow lost the ability to produce seed (bananas, figs and naval oranges) where as others need mankind to keep their offspring in existence (Corn, Wheat, Rice.) as they are no longer able to out compete naturally occurring ‘weeds’. With all that said the closer a plant variety is to it’s original wild origins the better it tends to be in fighting off insects weed competition and handling changes in the environment. A good example can be found with Lettuce and Chicory, the former having been cultivated for centuries but is still competitive. The latter (chicory) in its basic format is still pretty much a roadside weed, but with good soil and fertilizer becomes a productive perennial leaf green.  In respects to the lettuce some lettuce seed has been known to last for decades in dry storage with modest losses in viability. Old seed may not necessarily be bad seed but for the purposes of growing crops it may not produce the necessary number of plants you seek.

Needless to say, like any other living thing you handle the seed itself requires a few things to maintain most of its viability. We at the Skye project store our seeds in a plastic BPA-free container that has an internal rubber gasket to prevent moisture from getting to the seeds. We also use a few of those little silicon gel packets in the container to reduce internal humidity to prevent any damage to the seeds. The container is typically stored at room temperature away from direct sunlight.

The seed packets above are from a variety of sources ranging from seed saved in our own test garden to certified organic seed and on to major commercial types.
Storage aside there are some terms you should know in regard to the source of your seeds take a look over these terms and then look at your seeds and see what you’ve got.

Cultivar
Cultivar is an amalgamation of the words Cultivated Variety. A cultivar is a specifically cultivated cross or breed which has been selected specifically for a special trait, such as Clemson Spineless Okra which was cultivated and selected for the lack of stiff bristles on the pods. For note Clemson is also one of those varieties that has been called a heritage or heirloom breed but no solid evidence verifies or denies it’s status.

F1 Hybrid
F1 stands for Filial First Generation hybrid; it is basically the seed from that first crossing between two parent plants that has not yet been tested for the stability of its characteristics. You may see a lot of F1 type seed in non-organic catalogs and seed racks as the major companies often rush these plants to market without full garden trials. Admittedly there is nothing wrong with an F1 hybrid, with exception of it being somewhat unreliable genetically.

Genetically Modified Organism (GMO)
The GMO is a laboratory-produced plant or seed where the genetics of the plant have been intentionally mixed in a way that otherwise would not be naturally possible. Prime examples include Starlink Corn, Roundup Ready Corn and Golden rice. The long term health effects of these products are questionable at best as any real study is often polluted by the biotech industry if it is unfavorable. When in doubt if the seed or plant you are holding is or is not GMO do no buy it. It is better to make due then to let GMO loose.

Heirloom
An heirloom is an older variety of seed that has been handed down through the generations. The issue with heirlooms is the difficulty in establishing what is and is not old enough to count as the word has became a marketing ploy for some seed producers (yes you burpee I mean you.).

Heritage
Heritage varieties are heirloom varieties that were famous at some point or another for some reason. For instance the specific varieties grown at President Washington’s estate would be heritage varieties because of where and when they were grown. Often such varieties have some noted historical role such as Nankeen Cotton which played a part in the American Civil War as well as in slavery.

Hybrid
A hybrid is merely a cross between two similar plants that produces seed that may or may not have the desirable traits of one or both parents. Typically hybridizing is done through pollen transfers. Hybrids aren’t as bad as many make them out to be as they are often confused with ‘Man-Made’ hybrids and GMO hybrids.

Man-Made Hybrid
The MMH is a hybrid between two similarly related plants in a specific family. This process often involves manual pollen transfer and the intentional exclusion of natural pollinators to attempt to create a normally unlikely cross between two plants. Some examples of such crosses can be found in the Faux Haworthia (aloe x haworthia), the Gasteraloe (Gasteria x Aloe) and a large number of house plants and annual flowers. The MMH isn‘t necessarily bad because there isn’t supposed to be any actual genetic manipulation however the product plants that result could be pretty bizarre looking, sterile or even extra aggressive.

Open-Pollinated
Open-Pollinated seeds or OP seeds are ones produced from parent plants where nature is allowed to take it’s natural course and pollinators such as bees and butterflies do all the usual work. A lot of the non-purple color varieties of Cherokee heirloom type tomatoes were first produced in this way. Ideally OP seed should be the only way seed is produced but corporate agriculture seems to have other plans.

Variety
The term variety is used to indicate the plant or seed in question is somehow a variation on the primary variety. For instance, Yellow Brandywine and Pink Brandywine are varieties of the Brandywine type tomato. There generally is nothing wrong with a variety because it is often the product of a natural mutation some aspect of unintentional selection. As with GMO seed if there is a doubt on it’s origins do not buy it.

Wild
The term wild is often applied to seed that is very close to it’s genetic origins, Currant tomatoes, dandelions and chicory are all virtually identical to their wild origins. Wild seed isn’t a bad thing but always make sure you have absolute identification of the plants they produce.

Weed
I know you all have heard the adage ‘a weed is a plant out of place’ or ‘A weed is a plant whose virtues have yet to be discovered.” This is true and I often refer to weeds with quotes because most of them do have a use. Corporate agriculture on the other hand makes profit from telling you that weeds are the downfall of civilization or well at least your yard. Most of them can be used to indicate soil conditions and weather patterns. As with Wild seed, always verify what you have before you eat anything.

With all that covered there are a number of terms being used on the market now that certainly do not help the average gardener make the best decisions for him or herself. Below is a list of a few seriously organic seed sources that do not use GMO seeds and have a good reputation for providing excellent seed and plant stock to the Skye Project

Baker Creek Seed
High Mowing Seed
Richters Seed
Southern Exposure Seed
Seed Savers Exchange

With all that said if you hardcore gardeners out there are on track by now your hot seasonal such as eggplant and peppers should have been started a week or two ago, and your ready to push on to tomatoes and other less temperature sensitive plants. If not you should get started since the weathers trying to turn more mild spring is approaching rapidly. Check in at LITFM next week for our official 2013 plant list and the next phase of our current topic. As always Folks keep ‘em growin!
