I first heard the old adage of “no bare ground” while working for Gordon Tooley and Margaret Yancy at Tooley’s Trees in Truchas, New Mexico. Gordon espouses many philosophies on life and farming. However, the philosophy of “no bare ground” didn’t completely resonate with me in dry-land New Mexico. Not long after I started on the Seed Production Farm at High Mowing, our Seed Production Manager said the same sentence, “no bare ground”. I am not sure if Sir Albert Howard woke his wife Louise in her sleep, muttering this sentence. Or maybe the thought first crossed J. I. Rodale’s mind when pondering soil health and organic gardening. The idea of keeping ground covered, however, seems intuitive. A drive across the expanse of the Dakotas, Nebraska, Iowa or Kansas, through the middle of the country, through hundreds of thousands of acres of some of the world’s most productive landscapes crystallizes intuition. However, the invisible hand of herbicide forces the landscape into repose between plantings. These acres wait to be planted and while they wait, time has slowed and ecology is frozen. The land lies lifeless.
As organic seed producers, we annually propagate life to be lived again the next year. Every spring, mostly with seed we’ve saved, we begin the process of growing living vegetable seed. To grow strong living seed, we work to maintain and build a healthy living soil. Cover cropping serves as a key component to building healthy soil. We sow cover crops in spring and fall, with some cover spread in summer. Before sowing cover crop we run Perfecta cultivators over the ground to be cover-cropped. The Perfectas gently disturb the soil, overturning any weeds that are beginning to germinate.
Spring Cover Cropping
This year we are spring cover-cropping just over 10 acres. We spring cover crop with field peas and oats. We mix a 2:1 pea to oat ratio and sow the seeds with a PTO driven broadcaster seeder on the tractor. We spread rates of 100 lbs of peas and 50 lbs of oats per acre. According to the Northeast Cover Crop Handbook, a mature oat spring cover can produce 6,000-8,000 lbs of dry matter per acre; field peas can produce up to 5100 lbs of dry matter/acre. After the seeds are broadcasted, we cultivate with the Perfecta to better incorporate the broadcasted seeds into the soil. We have an old International Harvester grain drill that hopefully with enough love, WD-40 and elbow grease, we can make work.
Oats (Avena sativa) germinate well in cool weather, grow well easily, produce allelopathic compounds that suppress weeds, grow a fibrous root system that prevents soil erosion, and facilitates the upward growth of the companion planted legumes.
Field peas (Pisum sativum) and their associated beneficial bacteria fix atmospheric nitrogen into nitrogen compounds available to plants producing up to 172 lbs/acre of nitrogen. Both require minimal tillage to prepare a seedbed that was fall-tilled.
Fall Cover Cropping
Our fall cover crops are spread either on fields that were in summer seed production or in spring cover crop that was incorporated. We mostly plant cover crop in the fall with a mixture of winter rye, vetch, and crimson clover. We seed a per acre rate of: rye 30 lbs, hairy vetch 25 lbs, crimson clover 10 lbs.
Winter rye (Secale cereale) exhibits great cold tolerance, able to germinate in temperatures low as 34° F, and can take up excess soil nitrogen. Similar to oats, winter rye provides root structure below ground to hold soil and also above ground structure for legumes to utilize.
Rye produces around 3000-4000 lbs of dry matter per season. Winter rye also exudes allelopathic compounds that inhibit weed growth. Hairy vetch (Vicia villosa) fixes nitrogen and provides weed suppression.
Crimson clover (Trifolium incarnatum) provides fall weed suppression due to its ground cover type growth habit. Crimson clover fixes nitrogen and does exhibit some shade tolerance enabling it to thrive under Hairy Vetch and Winter Rye. Crimson Clover and Hairy Vetch can fix approximately 200 lbs of nitrogen/season. We manage our cover crops while also spreading compost and other amendments in the spring and fall.
Patterns in Our Cover Crops
A theme prevails amongst our spring and fall cover crops. The monocots–oats and winter rye–provide a root mat to prevent soil erosion, exude allelopathic compounds that inhibit weed growth, provide above ground structure enabling the companion leguminous crops upright growth, and produce considerable biomass that can be incorporated into the soil therefore building levels of organic matter.
The legumes–field peas, hairy vetch, and crimson clover–importantly, form the symbiosis with beneficial bacteria that fix atmospheric nitrogen into nitrogenous compounds available to plants, forming a dense canopy shading out weeds both when living and after winter-kill, providing plant matter that can be incorporated into the soil.
Inadvertently, areas of the farm where we grow Brassica seed are cover cropped during seed harvest. Enough seed escapes in the dry seed harvest process that beautiful cover crops of mid-summer mustard greens take hold. Mustard greens suppress weeds, soil borne disease and release biofumigants into the soil that reduce numbers of predatory nematodes. Baby mustard greens also provide a tasty mid-day field snack.
Every season on the High Mowing Seed farm, like farms everywhere, our farming gets better. The evolution of our cover cropping practices hopefully will mature into a system with less tillage and less of a need for off-farm inputs. As long as we keep muttering to ourselves, “no bare ground”, we work toward a living landscape that yields a strong living seed.

Growing is an act of faith and foresight. Faith because you plant these seeds, tiny embodiments of life, small parcels of potential, and you trust that with the proper conditions and care, they will grow. Foresight because in farming and gardening, you are always thinking seasons ahead, anticipating the earth’s next rotation.
I began gardening with my father when I was very little. I don’t really remember much about it actually, as if it was so commonplace as to not be special. But special it was because my love of the garden as well as the woods both came from my father and directly led to my passions for seeds. He, in turn, was raised on an early organic farm in California in the 30′s and 40′s and told me stories all about it as I was growing up. I feel connected to that farm but when I drove past it two years ago, it was all houses – like a lot of houses! But his childhood gardening and farming led him to do the same with me. When I first had kids, I couldn’t wait to do the same.
When the girls got to be about 4 and 6 or so, they were regularly getting sent on missions to the garden by Heather and I. Carrying a basket and scissors with a little list in their heads was really fun for them. Many times when we had friends or extended family over for dinner, our girls were very proud to show them “their” garden and would very capably snap off kale and chard leaves or pull some carrots. Imagine being a grown-up and having a five year old identify veggies that you don’t know? That’s a special kind of pride that always made me smile. It also made me question how far we can get in life sometimes without knowing such basic things as how to harvest. When a plant is ready, which leaves do you pick, how do you get them out of the ground without breaking the tops off? My girls seemed like little geniuses in a country of food system illiterates. I could tell that they were proud of themselves and what they knew. And it was a good motivator for them too.
I didn’t know what to expect in May 2009 when I started my first day as a farm crew member. It was on a small start-up farm in Northfield, Vermont called the Green Mountain Girls Farm. It was their first year running a veggie CSA, I was their first employee, and as the season progressed there were many more firsts to be had. Fresh out of college with a BA in Environmental Studies and English, I decided to spend the summer on a farm, deepen my relationship with the food I ate, and hopefully start to eat meat again. (I knew that if I were to give up vegetarianism after six years, I’d have to be intimately connected to the animal I ate.)
Whether you plan your time or not, you’ll be busy. The difference is that with a daily, weekly, monthly, and seasonal plan, you give yourself the gift of foresight and end up with fewer things on the “urgent” list and more on the “important but not urgent” list, so when the pigs decide to take a walk-about or a hot dry week forces you to spend days irrigating by hand, you’re not completely thrown off your rhythm. Planning will also allow you to work on projects that will improve your efficiency and the overall health of the system (maybe it’s time to get a new fence charger or finally set up drip tape), which in turn affects your mental, emotional and physical health—feeling stressed and at your wit’s end never helps anything, so take a half hour each morning to eat breakfast, drink some tea or coffee and go over the to-dos for the day.
Working in the trials field at High Mowing taught me how to take record keeping to a new level, and while it isn’t necessary for a CSA to spend the amount of time HMS does on record keeping, it is good practice to keep notes throughout the season.
In my mind, I am a now junior grower. I figure you get one freshman year, and then a bunch of sophomore years. After 12 seasons, I am unwilling to consider myself a senior grower, but I get a little closer every day. I remember when I first started farming I felt the need to see everything on the farm everyday. There was so much going on it was hard to know what to pay attention to and what to look for. It took a little while before I had a handle on how fast plants change from day to day and how quickly field conditions can change. Now that I have a few seasons behind me, and am familiar with the varieties I grow, I can see a little further into the future and get a feel for how the farm will look. I am still amazed at how quickly weeds can pop and become an issue, but that’s a different topic for another day.
One of the most important tools that I carry on my walks is some emotional armor. These walks are often where the problems get discovered. My motto is “Detach and Persist” and I know that I need let go of the disappointment and focus on the work. There are times when what I learn from my walks is the beginning of the end for a particular planting. Keeping the emotion around the crop out of the decision making process is a good skill. It’s ok to be upset, but it’s better to move on quickly to the next step when things aren’t going the way they should. The longer a problem goes unattended, the worse it inevitably gets, and sometimes the best solution is to till it under.
In the fall of 1995, I found myself living in the loft of a barn, surrounded by a heap of hay, piles of mouse droppings, my pack of belongings, and a small mattress. Below me, the cows, horses, and sheep sighed loudly all night long, and I jolted awake each time one of them peed. My six work days a week were filled with harvesting, weeding, carpentry projects, cooking meals, and asking vigorous questions of the other apprentices and farmers about how and why everything was happening. And at the end of each month, I received $100 in pay.
Hours and hours of mundane tasks with co-workers can lead to unexpected sharing and personal closeness. The bonds of friendship that I’ve forged working on farms are some of the strongest in my life. But from a management perspective, this closeness needs to be balanced with an expectation of professionalism and an establishment of boundaries that makes everyone feel safe and supported in the farm’s work environment. Below are a few guidelines to managing a professional and friendly farm work environment:
Staff empowerment. Because I don’t enjoy the “manage” part of management, it’s really wonderful to realize that trusting farm staff with responsibility eases your burden while enhancing their experience. It’s hard for me to let go of jobs I enjoy, and it’s also hard not to quickly glance at a project that is underway and wonder what the heck is going on. But knowing that a job gets done well and efficiently is far more rewarding than gazing over someone’s shoulder and offering suggestions of how you would do it. I learn only by doing things (and by messing everything up once first); so offering our staff this opportunity to learn by taking on individual tasks strengthens our farm in the long run. It also offers seasonal employees a strong vested interest in the farm – and keeps many of them coming back year after year.

Choosing your Varieties
Here in Northern Vermont, April tugs at our heartstrings as it dangles spring in front of us, while at the same time threatening one more winter storm to put our hopes for new gardens and fresh veggies on hold a little longer. Last year, we were all fooled by an early warm spell only to be pelted by hail the next week. Despite the unreliable spring weather, we can still find ways to brighten our days with veggies and fruits left over from last year’s harvest. My favorite way to do this: juicing!
We are fortunate at High Mowing Organic Seeds to have access to some of the highest quality seed sources available. This week two of our friends at Bejo Seeds, Inc. visited us here in Wolcott, VT. Bejo is a Dutch company that has two offices in the US, including a world-class research and demonstration farm in Geneva, NY. Jan and Tom joined us for a day at High Mowing to learn more about our needs and to further familiarize our staff with some of the Bejo varieties we sell.
