The January newsletter of the Piedmont Master Gardeners (The Garden Shed) has this sobering article about Invasive Jumping Worms by Cathy Caldwell. The article includes the all-important information on how to distinguish an invasive jumping worm from any other kind of earthworm (it’s not hard!), and what to do if you find one.
The conference was very well-attended, and not everyone at my workshop on Friday, or the Alliums Year-Round 90 minute workshop on Sunday morning got a handout. I promised to post them here, and now I’m making good. I’m also posting the handout for the third workshop I gave, Asian Greens in the Winter Hoophouse. This rounds out the set, and gives a chance to those who went to a different workshop at that time to get a look in.

Cold damage update
I reported very little damage to our hoophouse crops last week when it was 2F (-17C) outdoors. Since then, no plants keeled over, but some leaves are showing tan patches of dead cells, either where the leaves touched the rowcover. or where they were not properly covered. So, we have lost some leaves of senposai, a few of spinach, some on the yarrow we planted for beneficial insects. But, overall, I’m extremely happy with the good condition of our crops.
Mistake about potato yields
Yes made a mistake back in 2012, when I wrote Sustainable Market Farming, which I hope has been corrected in reprints since I was first notified of this in August 2019. If you have an older edition of my book, it might still have the error. In yield numbers on page 376, it says about potatoes, “Yields are likely to be 150 lbs/ac (168 kg/ha); 200 lbs/ac (224 kg/ha) is a good yield”.
“Yes, my mistake indeed! On page 45, I have the (better!) info that potatoes can yield at least 110 pounds/100 feet, or 49.9 kg/30m. I think I probably meant to write on page 376, that a low yield could be 150 pounds/100ft, which is equivalent to 11 tons/acre. In the metric system, that’s 223 kg/100m, or 24.4 tons/ha. Other sources suggest average yields could be almost twice this. And good yields, even 4 times the low numbers.
So it should say
“Yields are likely to be 11 tons/ac (24.4 tons/ha); 22 tons/ac (48.8 tons/ha) is a good yield”
That’s US tons of 2000 pounds, metric tons of 1000 kg. Or for a smaller scale, probably closer to what most of us are growing,
“Yields are likely to be 150 lbs/100ft (223 kg/100m); 200 lbs/100 ft (300 kg/100m) is a good yield”
At the Carolina Farm Stewardship Association Sustainable Agriculture Conference, in Durham, North Carolina, November 5-7, I facilitated a Farmer Round Table on Working Through Production Challenges. I started the event by providing stickers and asking participants to fix them on a chart, which had a circle divided into 16 segments, labeled Land & Space; Weather; Capital, Infrastructure & Equipment; Time Use & Planning; Quantities; Prioritizing; Labor; Crops & Varieties; Planting; Weeds & Pests; Harvest, Wash & Pack; Contingency Plans; Learning; Resources; Support; and Other Stuff.
I asked people to use red or pink stickers for their three worst production challenges, orange or yellow for their next worst, and green or blue for topics where they had once had a problem, and have since found a solution. (The reason for the varying colors is that I didn’t know how many people would be there, and used stickers I had on hand!)
Honestly, we could have made a full-day workshop, trying to cover all the challenges! Apologies to the people whose problems never got mentioned out loud.
We started with the category of Weeds and Pests as that had the most red and pink stickers, and spent a bit of time towards the end on labor challenges and a tiny bit of time on solutions that people had found to various problems. In fact, we spent most of the workshop talking about insect pests, from nematodes up by size, through flea beetles to potato beetles, Japanese beetles and harlequin bugs.
To make up for weed and pest management topics we didn’t get to, here are some updated resources from my first book, Sustainable Market Farming. This will also be useful to owners of my book, (as the links are now 9 years old), and anyone else looking for pest, weed and disease biological management.

In January 2020 I was part of a group tour of Cuban farming organized by the Organic Growers School. In 9 days we visited 9 farms, had several speakers address aspects of life (and particularly farming and environmental issues) in Cuba, had a couple of walking tours, ate many delicious farm-to-table type dinners and still had time for a salsa lesson.
When I got home I planned to follow up with a public slideshow, but instead we got the Covid pandemic. I made a series of blogposts, which you can revisit:
“This 9-day tour of Cuba’s sustainable farms, community gardens, and historical centers provides a rare opportunity to learn about the Cuban food system and learn about alternatives to corporatized agriculture. Participants will have the chance to:
Learn from farmers and food activists about Cuba’s transition to agroecological farming practices and its national policies that prioritize sustainable farming and hunger remediation.
Connect with farmers, consumers, activists, NGOs, policymakers, and experts working to transform the global food system.
Acquire the knowledge and strategies to create just, sustainable, local, and healthy food systems in your own communities.”
Check out the linked presentation for a summary of the January 2022 tour and for a sneak peek of the types of activities involved in the tour. OGS successfully operated a tour group in January 2022. No-one got Covid. OGS brought the first educational trip from the United States to Cuba since the beginning of COVID
On the website you can get your most likely questions answered: legal, financial and health requirements, sample itinerary, reasons to visit Cuba, reasons to go with OGS, reasons to value agroecology, and a one-hour Info session video. The trip includes bus transportation within Cuba, a minimum of 2 meals each day, 9 nights in casas particulares accommodation, a very good ag-knowledgeable tour guide and tour manager, and entry fees to various sight-seeing exhibitions.
CAFF - Extend Your Growing Season into Colder Weather with High Tunnels I’m spending October home on the farm, preparing and planting the hoophouse with winter crops. Meanwhile I’m applying to speak at quite a few sustainable agriculture conferences and preparing slideshows, handouts and talks. I’m going back to in-person conferences. We have very limited Wi-Fi in this part of rural Virginia and video-conferencing is just not possible. I managed to make some recorded narrated slideshows during the pandemic and I picked up more writing work. But there is an undeniable something I get from in-person conferences!
In the past year I’ve been at two in-person events: The very safely and carefully orchestrated PASA conference back in February, and the September CAFF presentation, half of which was outside touring the farm and half in a large airy lecture room. Now I’m lining up quite a few conferences. Go to my Events page on this website to get all the details, including links to register. Hope to see you at one of these:
I will be presenting a 75-minute workshop on Spring and Summer Hoophouse Use, especially how to manage extreme heat and diseases in hot and humid climates.

Alliums Year-Round (Brand New!)
Crop Planning for Sustainable Vegetable Production.
We are getting ready for fall and starting to plant our winter crops in the hoophouse.
I have written about transition to winter crops here: Planning and Growing Winter Hoophouse Vegetables (August 16, 2022). This post includes a bed plan, and links to lots of related posts, such as selecting and planning winter crops, bed prep, direct sowing and transplanting, and then caring for the crops, optimizing use of the space, harvesting, and what to do if something goes wrong,
Fall Lettuce Transition
From September 11-17 we sow to transplant in our greenhouse, and on September 15 and 24 to transplant in our hoophouse. This is our fall transition and I’ll write about that when the time comes.
On September 15 and 24, we sow leaf lettuces and romaines in an outdoor nursery bed. We transplant these into our hoophouse at 10” (25 cm) spacing. This is a bit closer than the 12” (30 cm) spacing we use outdoors. We will harvest outer leaves from the hoophouse lettuce all winter, so the plants won’t get as big as they do outdoors.
On October 23 we start sowing lettuce mix in the hoophouse. Baby lettuce mix can be ready in as little as 21 days from mid-spring to mid-fall, longer in colder weather. Our first sowing will be harvestable form 4 December to 15 May if we’re lucky, although if it gets too hot, this planting will get bitter and we’ll need to pull it up.
Baby lettuce mix is a direct-sown cut-and-come-again crop, the plants regrow and can be harvested more than once in cool seasons. We sow 10 rows in a 4’ (1.2m) bed, 4.5” (11cm) apart. Weed and thin to 1″ (2.5 cm). When 3″–4″ (7.5–10 cm) tall, cut 1” (2.5 cm) above the soil. Gather a small handful in one hand and cut with using large scissors. Immediately after harvesting, weed the just-cut area so the next cut won’t include weeds. Rake after harvest with a fine leaf rake to remove outer leaves and cut scraps. If you want to make more than one cut, you will need to remove anything that isn’t top quality salad while you can see it. Larger scale operations have harvesting machines.
We make four or five sowings of baby lettuce mix, sowing our last one on 15 February, for harvest starting mid-March, and ending in May when it gets too hot. By then we should be happily harvesting juicy lettuce heads outdoors and will have lost interest in the lettuce mix.
The soil temperature range for germination of lettuce seeds is 35-85°F (2-29°C), with 40-80°F (4-27°C) being the optimum range and 75°F (24°C) the ideal. At 41°F (5°C) lettuce takes 15 days to germinate; at 50°F (10°C) it takes 7 days; at 59°F (15°C) 4 days; at 68°F (20°C) only 2.5 days; at 77°F (25°C) 2.2 days. Then time to germination increases: 2.6 days at 86°F (30°C); after that it’s too hot.
Removing Shadecloth from our Hoophouse
We are now removing our shadecloth. Normally we would have removed the shade cloth in mid-September, or at least by the Equinox, but this year we are delayed a week. After 15 years with our initial piece of shadecloth we ordered a new piece. Well, we ordered two new pieces, because we mistakenly ordered a piece only half long enough. We bought a matching piece for the other half, and this winter we are going to sew the two pieces together with nylon twine, because the ends of each piece roll back, leaving a central gap about 6 feet long by September. Measure twice, order once!
Before next spring we need to replace quite a lot of the hooks the shadecloth ropes attach to. Next time we replace the big plastic we also need to replace the baseboards, as they are rotting and not holding the hooks well.
A reader passed on this tip: “When I ordered shadecloth for my hoophouse, I overshot each end by ten or twelve feet. We stake that out on either end, using six-foot T-posts, to give us a shaded area where air moving into the hoophouse’s open ends can be cooled before entering the structure. Every year in July and August, I’m grateful we did.”
Washing Down the Salts in the Hoophouse
Next week we will leach the salts that have risen to the surface of the soil and dried out there. My book The Year-Round Hoophouse has a whole chapter on recognizing, monitoring and reducing salts that have built-up in the hoophouse, and reducing the likelihood of problems in the future. There is also a chart of salt tolerance of various vegetables, so you can choose what to grow while you remediate your soil. Here I’ll just give a very short intro, in three slides. Click in the lower left of the first slide to move to the next one.
We are starting to close the doors at night when the temperature looks likely to drop below 50°F (10°C) outside. We had to trim down the grass to be able to push the doors to. We had to re-drill the holes the door-bolts (“cane bolts”) go down into. The doors have been wide open all summer.
In fall/winter/spring, if night time outdoor low temperatures will be below 40°F (4.5°C) here, we close the windows as well as the doors.
See my post Dealing with winter weather in your hoophouse (Jan 2022). Be ready to deal with snow and strong winds, extra cold temperatures, and holes in the plastic letting cold air in. If you have a double layer hoophouse, the air inflated between the layers adds strength to the structure, as well as thermal insulation. Holes are bad news.

I started to make in-person bookings again a year ago, then Omicron arrived and lots of conferences switched to being virtual. The only in-person event I attended this spring was the PASA conference, which I enjoyed a lot. I am still doing some virtual events, and planning some live ones too. Everything is subject to change!
As of right now I have two in-person events booked, and one new podcast interview. June and July are the months for speakers to apply to make winter and spring conference presentations, so I’ll be doing that! See my Events Tab for ideas I have of which events to apply to.
CAFF was developed to strengthen and expand our food and farming system, enhance local communities, and provide opportunities for farmers, food entrepreneurs and food system leaders.
Combining traditional and experiential learning opportunities, their Farm School and Apprenticeship programs teach the production and business skills to develop resilient and sustainable businesses.
CAFF is dedicated to increasing the number of thriving farms and farmers in Arkansas. To accomplish this, the center provides farm education, training, networking, and resources. Creating a supportive farm community network will bring more people into farming and help retain current farmers by increasing their success.
Join CAFF at the farm to learn about extending your growing season with high tunnels. Space for this class is limited.

“Isn’t too cold for the predators to be around, Pam? unless they hibernated in the greenhouse. but even so, it’s still cold in there at night. We have some aphids too in the tatsoi and some of the lettuce, so thank you for all the tips, and the life cycle. I had not quite realized that the cycle was so short. I grow borage in the hoophouse but in the ground – the plants get large and gorgeous with clouds of blue flowers in March and April – much bigger and healthier than anything I try to grow outside. The honeybees absolutely love it and they attract are a lot of other insects too.”
Yes, it has been still too cold for predatory insects to be around, until this week, when ladybugs greet us around every corner. Our idea with the flowering plants was that by starting the plants in the fall, we’d have actual flowers earlier than if we started in “spring”, and that perhaps the extra stresses would even cause the plants to flower earlier. Apart from the borage, none of the others have flowered yet (Feb 23). We likely need to fine tune our sowing dates. We sowed at the very beginning of September and the very end of October. That two-month gap probably has better sowing dates! We noticed that some of our plants were not very cold-hardy. Some died and some had to be pruned of dead bits. Since then, we started more flowers in our greenhouse on February 1. Another thing we’re noticing since early February is that the plants in pots dry out very fast. It’s probably better to get the flowers in the ground in the hoophouse and greenhouse as soon as they are big enough, as suggested by the results of my reader quoted above, with borage.We had thought that having them in pots would enable us to move them into trouble spots.
Vegetable Crop Resources, Especially Weeds
A newly released handbook from Sustainable Agriculture Research and Education (SARE), Manage Weeds On Your Farm: A Guide to Ecological Strategies by Charles L. Mohler, John R. Teasdale and Antonio DiTommaso, is set to help us all. I haven’t read it yet (although I am looking forward to that!), so this is not a review, But these are three big names in weed science, and SARE is well-known for providing solid information on sustainable farming.
I had the great good fortune to attend a workshop by Chuck Mohler years ago, and got some realizations that forever changed my approach to weeds. Top of the list is that some weeds, such as pigweed (amaranth species), don’t distribute any seeds until they have grown very big. Until that point they are not threatening next year’s farming efforts. We used to get huge pigweed plants in our sweet corn, and fatalistically did nothing once we were in there harvesting, somehow believing it was “too late”. No, it’s not! They hadn’t seeded. We started to make a practice of pulling the huge pigweed every two days while harvesting corn. Often it was necessary to stand on the base of the corn plant to hold it in place, while pulling the weed. Then all we had to do was drop the pigweed between the rows. Sweet corn ripens in hot weather and the weeds soon died, rather than re-rooting. All those big leaves sucked the moisture right out of the plants. Be extra careful if you have spiny amaranth. We have twice eliminated this weed form our gardens, by diligent hand-pulling, only to have it reappear a few years later!
Conversely, galinsoga forms seeds very soon after germinating, while still small. This weed is one to strike early and repeatedly. It readily re-roots in damp soil. Our strategy when we are too late to hoe and have to hand-pull them, is to shake off as much soil as possible, then to either twist and break the stem (if there are not many), or “shingle” the weeds, laying them down with the roots of one on top of the leaves of the previously pulled plant, providing a surface of roots all exposed to the air, and none touching the soil. This works quite well. Timely hoeing is much better, of course!
Manage Weeds has chapters on How to Think About Weeds, Cultural Weed Management, Mechanical and Other Physical Weed Management Methods, Profiles of successful managers,and then the alphabetical rogues gallery of grass weeds and broadleaf weeds.
This book and all the online information from SARE is free of charge. You can buy print copies if that suits you better. Other good resources from SARE, while you’re at their website, include several other books:
I enjoyed attending the in-person conference of Pasa Sustainable Agriculture. This is the first conference I’ve been to in person in two whole years. PASA did a lot to ensure the conference was as Covid-safe as possible. They limited the number of attendees (there were still plenty to ensure lots of chances to exchange information). Everyone had to test on their day of travel to the conference, and speakers had to test every day of speaking. For me that was all three days. Everyone was masked, nearly all with KN95 “real” masks. The hotel housekeeping staff only came in after we left. (We could have requested the service, but, heck, I can make my own bed!) In the workshop rooms, the chairs were spaced 6 ft apart. The trade show had wide aisles, and meals could be taken out of the dining room to a quiet spot. Just getting to be there was a big highlight for me! I left feeling energized and enthused, and very grateful to the PASA team for preparing such a successful event.
There were four sessions of workshops each day, with one-hour breaks between, allowing time to visit uncrowded trade booths, catch up with old friends, and make new ones. We were well-supplied with snacks and beverages during the breaks. There were socials with more snacks at the end of the day.
I did have trouble with the conference app, but then, my phone is limited in what it can do. Likewise I failed to upload my slideshows to the platform, so I ran them off my flashdrive. My pdf handouts did make it onto the app, so if you wanted one of my handouts, you can find it there and here:
Each of the ten workshop sessions had a choice of eight or nine workshops. I had thought I might hunker down in my hotel room when I wasn’t speaking, to minimize my chance of catching Covid, but as permaculture author Darrell Frey said “This feels safer than going to the grocery store!”
I enjoyed several workshops presented by others, including:
On-Farm Experience with Organic No-Till
Sam Malriat from Rodale
No-Till sequesters carbon in the soil, but simply never tilling does not improve the soil. Chemical no-till uses lots of herbicide. Don’t be obsessive about no-till. Shallow tillage can be a responsible choice, as incorporation of organic matter is valuable. Adding cover crops, compost or manure, grazing, and a good crop rotation, can increase the OM, and thus increase the soil water capacity enormously.
To overcome the challenges of no-till, you need a very good cover crop stand that will provide a thick mulch when terminated; a competitive cash crop; a way to plant into the residue, and a back-up plan in case one of the requirements doesn’t pan out.
Sowing corn into rolled and crimped hairy vetch does not work well, because corn is a heavy feeder and not very competitive. Better is to undersow the corn at V5 or V6 (stages of vegetative growth) with white clover or crimson clover in September. It’s important to get good seed to soil contact. The clover grows when the corn dies. This is in Rodale Country in PA. If the clover can be left growing until the second year, cabbage can be transplanted into it. His slides showed the success of this system after an unpromising start.
Pumpkins can be direct seeded in crimped and rolled (or mowed) winter rye. There is a lot of difference in thickness of the mulch between rye sown in August and October.
Organic Solutions: Pest Management
Drew Smith and Emily Gantz from Rodale
There was a big drop in pesticide use in the mid 1990’s as GMO crops came in. But then a big uptick as resistance to the GMO crops developed. Currently, almost all non-Organic seeds contain neo-nicotinoids, even though they provide no economic benefits.
Crop rotation is the single most important thing you can do to manage pests. Drew showed us the IPM triangle, and we worked our way up. To succeed in preventing pest infestations, planning of all aspects of growing the crop is vital. As is regular scouting of each crop. Cultural controls include the physical aspects of the planting. Other physical controls include mechanical aspects of growing the crop. Biological controls include encourage beneficials, releasing biological agents. Greater biodiversity provides greater stability. See Cornell Entomology https://biocontrol.entomolgy.cornell.edu/index.php
Native Pollinators: Identification, Habitat Needs and Resources
Sarah Koenig and Ryan Stauffer from the Audubon Society
There are 4000 species of bees in the US (20,000 globally). 70% of food crop species rely on honeybee pollination to some extent. Native bees mostly nest in the ground. Don’t kill them by compaction (or weedkillers!). Use native flowers to attract native pollinators.
Using Tarps to Reduce Tillage on Small Vegetable Farms
Ryan Maher, Cornell Small Farms & Bob Tuori, Nook and Cranny Farm
More growers are trying tarping for weed control, killing cover crops, maintaining a good soil temperature, avoiding crusting and compaction, keeping beds dry enough for planting and reducing dependence on single-use plastics. Challenges include the heavy weight, the aggravation of using sand bags, especially in windy places, ponding of rainwater runoff, and the frustration of providing perfect vole habitat.
After 28 days in summer, you gain 200 GDDs. Plant-available soil N increases by 2 or 3 times from the plant residues. How soon does it dissipate after removing the tarp? Tarping for 3 weeks after shallow tilling kills the living weeds, improves crop establishment and reduces weed emergence by up to 83%. Think of tarps as a tillage tool! Do plan for weed management after removing the tarp. Pigweed and amaranth can become worse!
Bob Tuori spoke about a SAREtrial of tarping in the Northeast. He compared potatoes grown with and without prior tarping, both patches with and without hay mulch after planting. The tarped area needed sandbags every 10-15 ft. The tarp was removed June 4, weeds were counted June 24, then the patches were mulched. (I hope I got that right). I did not write down all the results, but the only-mulch area grew 17.4 lbs per hour of work, and the tarp-only area grew 13 lbs per hour of work. See the SARE report for the details.
Harvesting Techniques for Small- to Mid-Scale Vegetable Farms
Julie Henninger of Good Keeper Farm and Matthew Lowe
We saw good tool and equipment storage, and learned the benefits of growing head lettuce on landscape fabric (no rotten bottom leaves, no weeds). Muir is their favorite lettuce for spring, summer and fall. At $3/head, a 95ft row planted at 9” spacing earns them $1300, if they have a 15% loss.
We learned the importance of sharp knives or scissors for cutting baby greens with minimal cell damage and browning. Theirs sells at $12/pound. They grow Salanova, which brings in $1140/bed at each cutting. If they cut whole heads, these bring in $1476 per bed.
For loose carrots, they sow rows in pairs 2” apart, with 6 rows on a 30” bed, using a stale seed bed and flaming. They sell 1000 lbs per week. Julie Henninger emphasized not wasting time by setting the carrots down in piles. Minimize the number of times each crop is touched. They have modified a cement mixer to wash 25-45 lbs at a time.
Training and communication are also very important. New workers must master the task first, before chatting. Minimize distractions. Send crews out with a strong role model each, to keep the crew working at a sustainable pace. If working with a crew with diverse abilities (eg children), provide a clear short task with a beginning and an end, to give a good sense of achievement.
I participated in the book swap, setting out some spare handouts I had in exchange for a couple of magazines. I enjoyed the Farm Innovations poster display of tools and techniques to improve production or save resources (or both). I liked that previous years’ posters were available as pages in several ring binders.
In the Trade Show there were 60-odd vendors. I checked in with Nifty Hoops, a company who will deliver a hoophouse and put it up for you in one day, or help you put it up, teaching as you build. We put ours up ourselves, in 2003, and we were inexperienced and slow, and had to work on it in the (hot) afternoons, after spending the mornings farming. At events when I talk about hoophouse growing, I’ve sometimes been asked if there are companies who will erect hoophouses (high tunnels), so it’s good to be able to pass on this contact. Nifty Hoops also sell interesting components such as DC-powered inflation blowers. (734) 845-0079. They have videos on their Facebook page
I picked up some publications from ATTRA, who have supplied me with great vegetable growing info since before the internet. (We used to call them up and ask for publications to be sent in the mail).
I also was fascinated by the Mini-Treffler, from OrganicMachinery.net, a manual rolling tine harrow for crops in beds.
The TINY Treffler is a hand drawn harrow with the working width of 80cm (2 ft 7 in), 100 (3 ft 4 in) and 130cm (4 ft 3 in)
Shares the same principle with the big Treffler harrows: in the row harrowing, adjustable tension and the patented tine suspension
Each tine follows the contour of the field and the downward pressure remains constant
The TINY is effective throughout the growing season in greenhouses or for small enterprises in vegetable production or seed propagation
Wheels extendable from one or both sides to straddle a bed
I gathered literature for our garden crew as well as our dairy, orchard and poultry people, and an assortment of free pens, notebooks, stickers.
PASA also had a virtual conference, spread out over a couple of weeks in January. I’m sure there was great information there too, but our rural internet is not up to the task of virtual conferencing, so I’m in the dark. Pasa intends to keep a virtual conference next year as part of the mix – it works better for farmers who cannot easily leave the farm, it reduces the carbon footprint of travel, and saves on travel and hotel or BnB costs. Maybe next year I’ll have better internet. Maybe Covid will have receded. This year’s conference was great! I look forward to next year’s!
