No-Till Growers and Josh Sattin collaborated to post this Hoophouse Tips video interview of me talking about our hoophouse:
After a Best Ever day on November 7, 2019, when 876 people viewed my website (4,855 that week), December has been quiet. It’s not a big gardening month for most of us, and the month is full of holidays. And then there’s the urge to hibernate.
Nonetheless, I have been reliably posting every week, and you might have accidentally missed something, while entertaining the visiting aunts and uncles, or rushing to get the carrots harvested, or something involving food and drink. Here’s a chance to find the lost treasures!
Soil Tests and High Phosphorus Levels close behind at 9,503. High phosphorus is a worry for organic growers, especially those using lots of compost, as it can build up each year.
How to Deal with Green Potatoes at 8,613, with sustained interest through August, September and November. Obviously we are not the only growers with this problem, caused by light getting to the tubers.
A 10 pound purple ube grown in North Carolina by Yanna Fishman.
Here’s an ube, a true yam/Dioscorea alata. This amazing photo is from Yanna Fishman in Union Mills, NC. She grew this in her garden. It’s all one root, one season’s growth from a small section of a root. She has also had success growing both the white and purple yam from aerial tubers.
Grower Jim in Florida has more information on ubes.
Yanna’s second photo shows a selection of unusual roots she grew. She is launching herself on a ‘tropical perennials as temperate annuals’ trial

Josh Sattin of Sattin Hill Farm came out to our farm to film me talking about farming and Twin Oaks Community and you can see that here. Not sure if I’ve been around long enough to be a legend, but Twin Oaks has.
And a blog reader, Andy Montague, has passed along the info that his cauliflower was damaged by temperature around 19F (-7C), while his broccoli, cabbage, collards, and Brussels sprouts were unharmed. This illustrates that cauliflower is the cole crop most susceptible to cold.
Growing for Market Newsletter
Growing for Market magazine has launched a free monthly newsletter. The current issue includes articles on How to Improve CSA Retention Rates, and growing garlic (I wrote that one), and a special offer on a bundle of two no-till books. I see you can even get the newsletter translated instantly into a wide range of languages!
Key Perennial Crops information sheets (info from ATTRA)
The Savanna Institute has produced a new series of free “Key Perennial Crop” information sheets in collaboration with the Center for Integrated Agricultural Systems and the USDA-SARE program. The information sheets offer descriptions of 12 key Midwestern agroforestry crops: Aronia, Asian Pear, Black Currant, Black Walnut, Chinese Chestnut, Cider Apple, Elderberry, Hazelnut, Honeyberry, Northern Pecan, Pawpaw, and Serviceberry. They are available free online. Related ATTRA Publication: Fruit Trees, Bushes, and Vines for Natural Growing in the Ozarks
Researchers from Pennsylvania State University say thatforest farming could provide a model for the future of forest botanical supply chains. They say that transitioning from wild collection to forest farming as a source of medicinal herbs such as ginseng would create a sustainable supply chain, not only in terms of the environment, but also in terms of social justice for people who harvest the plants. The researchers point out that forest farming would allow more transparency in the supply chain, which could lead not only to better-quality herbal products, but also to a reliable and stable income for forest farmers.

The Southern SAWG Annual Conference is well-known for providing the practical tools and solutions you need at our annual conference. It is the must-attend event for those serious about sustainable and organic farming and creating more vibrant community food systems! This popular event attracts farmers and local food advocates from across the nation each year. This year, we have 101 “field-tested” presenters, a full slate of hot-topic conference sessions and pre-conference courses, five field trips, a forum, a poster display and a trade show. New this year! 2020 Special Topic: Agricultural Resilience in a Changing Climate.
In the hoophouse we are perhaps half way through our bed preparations. The Tokyo Bekana was the first crop we transplanted from our outdoor nursery bed, and it’s looking very sturdy now. We’ve also transplanted some Yukina Savoy and the first of the lettuces.
Cherry Belle radishes in the hoophouse, early October.

The crops we direct sowed in early September are growing well, and we are harvesting the radishes and some of the tatsoi and Bulls Blood beet greens (thinning to 6″ apart). The spinach is big enough to start harvesting but we haven’t needed to yet.
The newer sowings (the second radishes and the first brassica baby salad mix (mustards) have emerged and are ready to thin to 1″. Sometimes we use thinned seedlings as a salad garnish, but it takes more time than simply pulling them out, and it takes attention to keep them clean.
This summer we grew more cover crops rather than seed crops, which we have been growing in summer for several years, because we were short of workers. In the photo below you can see some healthy cowpeas I’m going to be pulling up later today, as well as some pulled up and dried buckwheat. We don’t dig our cover crops under, just let them die on the surface for as long as possible, shedding bits of dead leaf, then haul them to the compost pile. With the cowpeas, we hope to leave the nitrogen nodules from the roots, by ripping the plants up roughly!
These cowpeas have been cut back two or three times over the summer, to keep them manageable. At one point, they were black with sooty mold growing on aphid honeydew. We wondered if it was going to be a bigger problem, but after we cut the plants back, most of the aphids seem to have died. We also got a healthy population of ladybugs.
I gather readers are planning for winter, as many folks have been visiting my Winter-Kill Temperatures List of hardy crops. I update this list every spring, with the info from the previous winter. It’s useful for planning harvests based on forecast temperatures, and it’s useful for planning which winter crops will grow in your location, either inside or out.
On the same theme, I just discovered the WeatherSpark website which provides “The Typical Weather Anywhere on Earth”. Enter your nearest town or airport and you get clearly explained info with fascinating graphics of how the weather goes over the year in your locality. Note this is not a forecast site, it’s about average weather for each place. Useful to people who’ve recently moved and want to know what to expect this winter, or to new gardeners who haven’t paid so much attention previously. Or to those who want to check their assumptions (I really thought the wind was out of the west more of the time than records say). There are charts of high and low temperature, temperature by the hour each month, cloud cover, daily chance of precipitation (both rainfall and snowfall), hours of daylight, humidity, wind speed and direction and solar energy. A big help in making wise decisions. I know that climate change is going to cause havoc with averages, and we’ll need to learn to become better weather forecasters individually, and to use soil temperature and other metrics to decide when to plant. But this website explains things well.
The October Growing for Market is out. Flower farmer Erin Benzakein writes about getting to grips with the marketing side of running a farm. She encourages farmers to get good photos, step out from behind the camera, and dust off their website. I could use some of this advice! (I’ve been very busy writing a hoophouse book, and have necessarily paid less attention to giving presentations and to rejuvenating this website!
Kai Hoffman-Krull writes about on-farm trials of bio-char. I’m looking forward to reading that. Jesse Frost writes about winter CSAs and profiles some he visited. Chris Bodnar covers Italy’s thriving agricultural co-ops and asks if this could be a model for the next phase of the locally-grown movement. Lastly Zach Loeks offers the first of a two-part series on Transitioning to a permaculture market garden.
The September/October issue of Organic Broadcaster is also out. Articles include attending to soil health to improve production; the top reasons customers buy organic foods (accountability, environment, health); interseeding cover crops in cash crops; an interview with farmers in the MOSES Farmer-to-Farmer Mentoring Program; designing an efficient pack shed; and selecting the right meat processor.
Lastly, the campaign www.keepthesoilinorganic.org has posted a letter a letter recently sent out by farming mentor Eliot Coleman about the travesty of allowing hydroponics to be certified as Organic. Hydroponics is a system of growing plants anchored in holes in plastic tubes, or in blocks of inert material, and feeding them with a liquid solution of things that work to produce mature plants. The arrogance of imagining we know everything a plant needs is astounding! The idea that all the many complex ingredients of soil can be replaced with a synthetic concoction is staggering!
Eliot Coleman’s letter includes these quotes:
Organic farming is best defined by the benefits of growing crops on a biologically active fertile soil.
The importance of fertile soil as the cornerstone of organic farming is under threat. The USDA is allowing soil-less hydroponic vegetables to be sold as certified organic without saying a word about it.
The encouragement of “pseudo-organic” hydroponics is just the latest in a long line of USDA attempts to subvert the non-chemical promise that organic farming has always represented. Without soil, there is no organic farming.
Eliot Coleman will be a speaker, along with Fred Kirschenmann, Enid Wonnacott, Jim Riddle, Will Allen, Jeff Moyer, Dave Chapman, Anaise Beddard, Lisa Stokke, Tom Beddard and Linley Dixon at the Jacksonville Rally of the Keep the Soil in Organic movement. Oct 31, 2017 at 12:45 pm – 2:00pm EDT. Omni Jacksonville Hotel, 245 Water St, Jacksonville, FL 32202, USAThis Rally will be a gathering of organic farmers and eaters from all over the world. The march will begin at the Omni Jacksonville during the lunch break from 12:45 to 2 PM on Tuesday, the first day of the NOSB meeting. There will be a 5 minute march to The Landing from the Omni. Lunch will be available at the Rally. For more information, call Dave Chapman at 802-299-7737.
Starting with what’s being harvested now – squash and zucchini are coming in nicely. The hoophouse Gentry yellow squash (chosen for being fast-maturing) is coming in by the bucketload, and the outdoor yellow squash and zucchini have started producing.
Cold-hardy Winter Vegetables,on Saturday 6/10 at 11 am on the Yanmar Sustainability Stage, immediately followed by book-signing at the Mother Earth News Bookstore noon- 12.30.
Producing Asian Greens on Sunday 6/11 at 3.30 pm on the Heirloom Gardener Stage.
I’m also doing demonstrations of tomato string-weaving at the New Society Publishers booth 2611, near the Mother Earth News Stage (not the Bookstore this time), at 10 – 10.30 am and 3-3.30 pm on Saturday and 10 -10.30 am, 11- 11.30 am and 2- 2.30 pm on Sunday. Check out my Events page to see the pink sparkly tinsel tomato plant models I use!
At the Heritage Harvest Festival near Charlottesville, Virginia, on Friday September 8 (the Premium Workshops before the main Festival), I’m presenting on Growing Sweet Potatoes at 3.30-4.30 in classroom 7, followed by book-signing at the Monticello Bookshop.
The June/July summer issue of Growing for Market magazine is out, and includes my article on Hoophouse soil salt buildup. This is an issue we have been dealing with – we see white deposits on the soil. I did a lot of research and found ways to water the salts back down deep in the soil profile. I also gathered information on how to measure and monitor salinity, and how to understand the test results and their different testing methods and different units of measure. I learned about salt tolerance of different crops, the plant symptoms of excess salinity, and how to prevent the problem in future. This topic is rising in importance as more people use hoophouses with drip irrigation systems. We were blithely ignorant for our first several years of hoophopuse use, as salinity takes a few years to really develop, and there wasn’t much information available.
I’m also looking forward to reading the other articles, especially Summer lettuce lessons from Southern growers by Jesse Frost. There are some great photos of beds covered with hoops and shade-cloth, which show a good system. I always appreciate articles written for southern growers, which can be in short supply.
Daisy Fair in Utah’s zone 5 has written about moveable tunnels with in-ground hydronic heat. So there’s information for cold climates too. Sam Hitchcock Tilton has an article with tips learned from Dutch and Swiss farmers. Robert Hadad advises on careful monitoring of costs of production in order to actually make a living from farming. The flower growing article in this issue is from Debra Prinzing and is about American Flowers Week, a chance to highlight American-grown flowers with some light-hearted fun photos.
The May/June Organic Broadcaster just arrived in its paper format – I’ve had the digital one for a while. Good thing I’ve got that long car ride to Vermont this weekend to catch up on my farming reading!
The front page story this time is about Kansas farmers, Tim and Michael Raile, transitioning thousands of dryland (non-irrigated) acres to Organic steadily over the next 5 or 6 years. Dryland farming focuses on moisture retention. The Railes grow a wheat/corn/
sunflower/milo (grain sorghum)/fallow rotation. They are also trialing some ancient grains.
Organic production in the US is not meeting demand, and organic imports are increasing, including organic soy and feed corn, not just bananas and coffee. More farmers want to produce Organic poultry, eggs, milk and meat. And so they are looking for Organic feed at an affordable price. This is often imported, which raises issues about how Organic Standards vary from one country to another, and the bigger issue of sustainability – not always the same as Organic! Does it really make sense to ship in grains to feed livestock?
Harriet Behar writes about the true meaning of Organic and overall methods of production. It’s not just about following rules on allowed inputs and materials – it’s a whole approach to how we treat the soil, our plants and livestock.
Hannah Philips and Brad Heins share research on how cover crop choices can influence the fatty acids and meat of dairy steers. Jody Padgham writes about CSAs responding to competition and decreasing membership by offering more options on shares and delivery. Gone are the days of “One box, one day, one price” CSAs. Numerous modifications of the basic CSA model have sprung up to better fit the diverse needs of customers (members). Kristen McPhee writes about the Vermont Herb Growers Cooperative, which buys from various small-scale growers and aggregates orders to larger buyers. Other topics covered include lessons learned from Hawaii’s GMO controversy, paying for end-of-life care without losing your farm, and many short items and classified ads. As always, a newspaper packed with information.
And by the way, we’re also picking blueberries – ah! heaven!
I always know when garlic growers in slightly warmer or more southern climates are starting to find scapes (the edible firm flower stems of hardneck garlic) because my posts about scapes suddenly become popular! My posts “Garlic scapes! Three weeks to bulb harvest,” and “Garlic scapes to cheer us up” have been reread a lot recently, and Harvesting garlic is due for attention any time now. My Growing Great Garlic slideshow is here. Click the diagonal arrows to view it full screen.
And sure enough, our own scapes are ready too, even though this is a week earlier than usual.We harvest two or three times a week until there are no more. I love garlic scapes as one of the first outdoor crops of the spring, and a flavor different from leafy greens and stored roots, the staples of early spring.
Our tulip poplars are flowering now too, also early. Our average date for those is 5/1, and we’re a few days ahead of that. When I was a beekeeper it was important to be ready for the tulip poplar flowers, because that was our big nectar flow of the year, and I had to dash out to the beeyard and stack up 5 supers on each hive. I had to give up on the beekeeping because the combination of lifting heavy boxes and twisting was hurting my back too much. Oh, and those heavy boxes were full of thousands of stinging insects, but I didn’t mind that bit as much. The flowering of tulip poplars and the germination of ragweed are both phenology signs that signify that the Growing Degree Days have reached 200 (on a base of 50F) and that conditions are warm enough to sow sweet corn. Myself, I watch the young leaves on the white oaks and when they are the size of a squirrel’s ear, I decide it’s warm enough for corn.
This weekend I will be at the Mother Earth News Fair in Asheville, NC. Click the link to see the location, the workshop schedule and the list of vendors who’ll be there. I’m presenting two workshops, Growing Sweet Potatoes from Start to Finish on Saturday 5/6 at 12.30on the Yanmar Sustainable Agriculture Stage, followed by book-signing and chatting at the Mother Earth News Bookstore; and Succession Planting for Continuous Vegetable Harvests on Sunday 5/7 at the Heirloom Gardener Stage.
Of course, you’ll need to be there and hear me speak to get the most out of it. I’m also doing short demonstrations of How to String Weave Tomatoes at booth 2800, New Society Publishers (near the Bookstore) on Saturday at 10 am, 11 am and 5 pm, and on Sunday at 10 am and 11 am. They’re half-hour time slots. My table top demo kit uses #2 pencils and pink tinsel.
The May issue of Growing for Market magazine is out, including my article about growing seed crops in hoophouses. I interviewed Clif Slade, founder of the 43560 Project at Virginia State University, about several creative sequences of food crops and seed crops he has grown in a high tunnel. (Collards, okra) as well as plant starts (sweet potatoes, onions). He farms in Surry County, Virginia.
Also in this GfM, Simon Huntley of Small Farm Central encourages small farmers to set aside two hours a week for a quick and efficient bit of online marketing “One Photo,
One Paragraph”. His goal is to help farmers stay in the spotlight with their products, without having to spend a great deal of time on it in the busy season.
Conor Crickmore has an article about preparing and laying out no-till permanent raised beds very precisely in a hoophouse. He uses the Quick Cut Greens Harvester to mow off over-size baby salad crops to clear the bed prior to broadforking and adding needed soil amendments.
Spencer Nietmann writes about what it really costs to start a farm. Jesse Frost discusses various types of plastic to cover hoophouses (high tunnels), and lastly, Jane Tanner writes about native perennials for flower farms
