More on Summer Pests

Last week I wrote about hornworms. The Alabama IPM Newsletter has a good compilation of articles on tomato worms and various other insect pests. Hopefully you don’t need to read up about all of these!

Hang in there! Be careful what you wish for in terms of early frosts!


The August issue of Growing for Market is out. The lead article is Serving the Underserved by Jane Tanner. It’s about small farms connecting with people who are struggling financially and cannot easily feed their families good food. Examples include people working for food, gleaning finished crops, farms donating to shelters and other organizations, accepting SNAP cards at farmers markets, and an incentive program to encourage people to use SNAP entitlements to buy produce. Posting a photo of a SNAP card at your booth can help people using the cards feel welcome. The author encourages farmers to take flyers to distribute in the waiting rooms of agencies where people enroll for SNAP, WIC and other benefits. A approach used in central Texas is to post photos of available produce on popular Facebook groups for Spanish speakers that otherwise feature cars and jewelry for sale. The article is packed with ideas.

Tumbling Shoals Farm in mid-March

Ellen Polishuk’s Farmer to farmer Profile this issue features Shiloh Avery and Jason Roehrig of  Tumbling Shoals Farm in NC. Here’s the very short version:

Tumbling Shoals Farm

3 acres certified organic

7 high tunnels ( one heated)

1 Haygrove tunnel

66 % FM, 26% C SA, 8 % wholesale

2018 is year 1 1 for this farm.

Ellen visited in mid-March, on the farm crew’s first work day of the year, when there was snow on the ground. The farmers made a thoughtful review of their first ten years, and a plan for the future. They decided to expand in 2017 to increase net farm income and quality of life. This involves hiring one more full-time worker for the season, for a total of five; building a heated  high tunnel (for early tomatoes); and providing a four-day-weekend paid vacation for each employee during the dog days of August. Not everything went according to plan. Terrible wet spring weather led them to the somewhat desperate decision to also work a winter season too, to meet their income goal. This didn’t meet their quality of life goal, as you can imagine! The original investor for the heated hoophouse fell through, but they were able to finance it themselves. Everyone benefitted enormously from the little August break. For 2018 they are going to focus on their most profitable crops (they dropped strawberries, sweet potatoes, regular potatoes, winter squash and cut flowers.) Ellen commended them for their bravery in taking the difficult decision to drop “loser crops”. I know what that’s like. As Ellen says

” There is history to battle, habits to break, customer wishes to deny, and maybe even some ego to wrestle with.”

The article continues with info on addressing soil fertility outside and in the tunnels, buying selected machinery, and running a Lean packing shed. For more photos from Ellen’s visit, go to tinyurl.com/y7r8vr5a.

Start Your Farm book front cover

For more information go to Ellen Polishuk’s website. (Her new book Start Your Farm will be out soon, and I will review it on my blog.)

The next article is on when to call in a book-keeper and when a CPA, by Morgan Houk. “Why are we asking ourselves to be our own financial advisors too?” We have many other hats, we don’t need this one. Rowan Steele writes “Working Together: Oregon multi-agency farmer development program grows farmers.” This is about providing opportunities for the next generation of farmers, and lowering the average age of Oregon farmers below 60, ensuring that food production continues, and that the land is well cared for. Doug Trott writes about protected culture flower planning, from am exposed hillside in west-central Minnesota. Flower growers everywhere will get encouragement from this careful farm research and practice.

Year-Round Hoophouse Book Update

 The Twin Oaks Indexing Crew has finished indexing my new book. Very thoroughly, I’m happy to say – what farmer has time to deal with a poor index when they are in a hurry?

All the typesetting is done. Next stop is at the printers. This will take five to six weeks. From the printers it goes to the warehouses, then out to the stores. I should have copies for sale at the beginning of November! I sign all the copies I sell direct through my website and at sustainable agriculture conferences and similar events I attend. Yes, it is possible to buy the book for less money, but you don’t get a signed copy, and you won’t have the warm heart that comes from knowing you helped support a small scale farmer and author. The amount that an author gets for a copy of the book sold depends on the price the buyer paid and the price the supplier paid. And there’s also the library for those with not enough money to buy.

 

Year-Round Hoophouse book update, Nematodes in hoophouse cucumbers, Organic Broadcaster.

I just completed another step on the way to getting my new book, The Year-Round Hoophouse, published. I proofread aver 300 pages of text over the course of five very intensive focused days. In the next four days I checked all the photos, including the color section. I replaced a few photos that didn’t come out clearly, fixed a couple of glitches (that’s what proofreading is for!) And I added up to 17 more photos wherever there was enough space at the ends of chapters. The index is being prepared, and another proofreader is also carefully working through the text.

Then the corrected pre-press proof will be prepared by early August, and we’ll be on track for the November 20 publication date, with the books coming off-press in mid-October and heading to the stores. ISBN 978-0-86571-863-0.

The finished paperback book will be 288 pages, 8″ x 10″ (20 x 25 cm) for $29.99 (US or Canadian). It will also be available in digital formats.

When we were clearing our early bush cucumbers from the hoophouse a couple of weeks ago, I found four plants at the east end of the bed with nematodes. I’ve written before about our struggles with root knot nematodes in our hoophouse, and indeed, you can read everything I know about nematodes in the Year-Round Hoophouse.

Here is another photo of the lumpy roots, with circles outlining the nematode lumps.

The July/August Organic Broadcaster is out. The first article is about a poultry system compatible with regenerative agriculture. Regenerative Agriculture is one of the sustainable agriculture movements that are springing up as an alternative to USDA Organic, which now allows CAFOs, hydroponics and other unhealthy, non-sustainable methods. The regenerative poultry system includes trees for shade, ranging paddocks where the poultry are rotated, and night shelter. The aim of the author, Reginaldo Haslett-Marroquin, is a fully regenerative supply chain, starting with what kinds of grains they feed the poultry and how they are grown. Farmers can reach the organizers of Regeneration Midwest by emailing [email protected].

The second article explains the consequences of USDA halting the Organic check-off as part of their program. The editorial introduces Organic 2051, a one-day conference (Feb 21, 2019) prior to the MOSES Conference, “to bring together leaders in the organic and sustainable farming community to chart the path forward for truly sustainable farming by the year 2050 and beyond, demonstrating our capacity to feed the world.”

Another article (by Matthew Kleinhenz) discusses biofertilizers and explores differences between an average yield increase which is sustained and throughout the field, and one that might lead to a similar average yield increase, but with a result that is widely fluctuating between one plant and the next, producing a few start yielders but fewer plants with an actual yield increase.

Bailey Webster writes about industrial hemp, an up and coming crop with mostly non-food uses, although the seeds are finding favor, touted as a “superfood”. Brittany Olsen writes about the MOSES farm mentorship program, Teresa Wiemerslage writes about the Food Safety Modernization Act Produce Safety Regulation and Laura Jessee Livingston writes about a new apprenticeship program training farm managers.

Another article by Bailey Webster explores a shocking case that looks like racism in rural Kansas (although of course it could be almost anywhere). Kansas farmer Carlos Valencia, who is is black and Hispanic, began managing a farm in Norton, Kansas that was owned by Golden Duck LLC in 2007. He was working for equity in the farm, rather than for wages, with the goal of owning it himself one day. He planned to raise poultry, and had submitted documents to the Kansas Department of Health and Environment to get farm operating permits to raise geese on a commercial scale. The paperwork was taking a long time, and if he was to raise geese that year and earn his living, he needed to get goslings on the farm while they were available. Geese do not produce young year-round, only February-June. Fully expecting to get his permits (the previous farmers there had an industrial hog unit), he bought 20,000 goslings. This sounds like a huge number to me, but I understand from the article that this is a modest start. In June, disaster struck in the form of an unusually strong hail storm that killed 800 of Valencia’s young geese. He chose a common practice on poultry farms: incinerating them. The local authorities caught wind of it, and worried that the poultry had died of disease. The USDA and the state biopsied the dead birds to check for disease, and found that there was no disease present. Continue reading

BCS Berta Plow, Proofreading The Year-Round Hoophouse, Tomato Foliage Diseases

Our new equipment – a Berta rotary plow.
Photo Pam Dawling

In recent years we have mostly hand-shoveled the paths between our 90ft x 4ft raised beds. If we have two neighboring beds ready to prepare at the same time, we might use the hiller-furrower on our BCS 732 walk-behind tiller. But frankly that didn’t do as good a job as the old Troybilt hiller-furrower we used to have, and if you went off-course, there was no chance of a re-run to fix it. With the Troybilt you could fix a wiggle by steering hard on a re-run, but the BCS wouldn’t co-operate on that. So there was less incentive to use the BCS. We would measure and flag the bed, and have a person with a shovel at each end of each path, shoveling towards each other. Then we raked the bed, breaking up the big shovel-dollops.

Now we have a Berta Rotary Plow from Earth Tools BCS, and we are hopping with joy. It is easy to fit and unfit on our BCS, easy to use and does a lovely job. We flag the midline of the path, plow up one side of the path and back down the other. We get straighter paths, beds almost ready to use (no shovel-dollops!), and we save a lot of time, and don’t feel so tired!

This week I am proofreading the Advance Proof of The Year-Round Hoophouse. A professional proofreader is also working through the advance proof at the same time, and the foreword and the endorsements are being written (or more likely, being thought about!).

So far, I have found a few inconsistencies to align. I guess I thought one thing when I wrote one chapter and something else a few months later when I wrote another chapter! I found a few tiny typos, even after so much careful checking here and during the professional copy-editing process. I found a few unclear bits, which I hope will now be clearer!

I relearned a few things I’d figured out for the book and then forgotten about! I impressed myself with seeing again all the information packed in there, from helpful tips to expansive over-views. I’m very much looking forward to having the book in my hands. Several more months yet. Publication date is November 20. New Society is taking pre-orders. When I’ve got some actual boxes of books I’ll update the Buy Now button here on my website and you can support-an-author and buy direct. I’ll sign the book for you!

Grow abundant produce year-round in any climate

Growing in hoophouses reduces the impact of increasingly unpredictable climate on crops, mitigates soil erosion, extends growing seasons, and strengthens regional food supply. The Year-Round Hoophouse teaches how to site, design, and build a hoophouse and successfully grow abundant produce all year in a range of climates.

Pam Dawling has been farming and providing training in sustainable vegetable production in a large variety of climates for over 40 years, 14 of which have been hoophouse growing. Pam’s first book is the best-selling Sustainable Market Farming: Intensive Vegetable Production on a Few Acres.

PB 9780-086571863-0/ 8 x 10”/ 288 pages/$ 29.99/Available November 2018

At the end of July or the first week of August we will pull up our hoophouse tomatoes and sow some soy as a cover crop until we are ready to prep the beds for winter greens. Our outdoor tomatoes are producing now, and as their yields increase, we’ll have no regrets about pulling up the aging hoophouse plants. We like to grow some heirlooms in there, and they are (in general) notorious for foliar diseases. I know some are disease-resistant, but we don’t only grow those ones! We did better this year at removing any lower leaves touching the ground, to dissuade any transfer of diseases from the soil.

Early in the season we had aphids and sooty mold, but ladybugs sorted out that problem. More recently we have had a little Early Blight, some Septoria leaf spot, and a sporadic issue that has concentrations of leaves with small silvery spots (dead leaf tissue). These are mostly located below webs of zipper spiders. Is it a disease, or the result of spider poop or dead prey detritus?

Update on my new book, and how to garden when it rains a lot

Update on the progress of my new book, The Year-Round Hoophouse.

My upcoming book has reached its next stage: copy editing. My publisher, New Society, pays a professional copy editor, who has just sent me his edits. My job this week is to look through them, approve or reject the proposed changes and fix anything only I can do (reformatting the dates in the tables is one of those things). I used many more commas than necessary, and had some clumsy phrases, which will all be swept away before you see the final book.

You’ve already seen the cover (above) and the table of contents. The book can be pre-ordered from New Society, for a 20% discount off the cover price of $29.99 ($23.99). Buying from NSP supports publishers and writers like me. You can also pre-order from Amazon, where the price today is $27.40. Publication date is 11/20/18.

Once the copy edits are finished, NSP’s designer will work on the interior layout of the book for a couple of weeks, then advance proof copies go to a professional proofreader and me again, and also to the person writing the foreword and those writing the endorsements on the back cover and inside.

When the corrections are made and all the contributions gathered, the book comes back to Twin Oaks for indexing, by the Twin Oaks Indexing crew for about a month (July/Aug). After that, it goes to the printers for about 5 weeks, then to the warehouse. If all goes well, I’ll have a copy in my eager hands in late October. I’ll be signing and selling copies at events I attend after that date. See my Events Page.

How to garden when it rains a lot.

We’ve been getting a lot of heavy rain in the past two weeks, and sometimes it’s a challenge to find garden work we can do. Of course, it’s very tempting to take some time off, and sometimes that is the very best thing. But the danger is of falling too far behind, so that the next couple of weeks become impossible. Here’s my list of tasks to consider before, during and after rain.

If you are expecting rain, get your transplanting done!
Photo Denny Ray McElyea

Gardening before heavy rain:

  • Transplant anything even remotely big enough, where you have the beds or rows prepared.
  • Sow anything due to be sown that week.
  • Prepare rows and beds (especially raised beds), so that you can plant as soon as possible, and won’t have to wait for the soil to dry enough to till.
  • Harvest enough to tide you over the rainy spell.
  • If you have 4 hours of good sunshine before the rain is expected, hoe small weeds and let them die.

Garden activities while it’s raining hard:

  • Catch up on planning, organizing, record-keeping and bill-paying.
  • Prepare some spare blog posts, newsletters or Instagrams.
  • Give careful consideration to contingency plans – perhaps you will need to drop a planting if too much time passes before the soil is workable again.
  • Update your task list and mark the priority tasks, so you can hit the ground running!
  • Repair equipment, sharpen tools.
  • Wash and sort gloves.
  • Order supplies.
  • Watch inspiring farming videos or webinars, or listen to podcasts. Include the crew, and follow with a discussion. The Twin Oaks Garden blog has a new post!
  • Research those burning questions you didn’t have time for before the rain. Exactly what does a spined soldier beetle look like?
  • If you have a hoophouse or greenhouse, get all caught up with tasks under cover.
  • Spring clean your packing shed.
  • If heavy rain is expected any minute, and you might have to stop in a hurry, do weeding, not planting. Bring only the minimal number of tools and supplies. Be ready to leave as soon as it thunders! Don’t hoe if it’s about to rain, it’s a waste of time. Likewise don’t leave pulled weeds on the beds before rain. They’ll re-root.

Gardening after heavy rain:

  • Work on mulched areas and perennial crops first, where you won’t get bogged down in mud. Weed asparagus, rhubarb and garlic. If no more rain is expected, you may be able to lay the weeds on top of the mulch (whether organic or plastic) and let the weeds bake. The mulch will stop them re-rooting. But if more rain is expected, haul the weeds off to the compost pile.
  • If you have very wet soil, where your boot-prints have depth, don’t go there! Sinking mud compacts the soil, which means the plants go short on air, which will stunt their growth and the soil will be slower to drain after future rains. Standing on boards is an option for harvesting or planting. Take two boards about as long as you are tall (or a little more), and set them end-to-end in the path or aisle. Work your way along the plants to the far end of the second board, go back and pick up the first board, and set it down on the mud ahead of you. The helps distribute your weight over a much bigger area, so there’s less compaction, and the boards leave a smoother surface for next time. You may have to backtrack one board at a time to extricate yourself from the mess, but this can often be worth doing.
  • Use a rain gauge to see how bad it was.

    Some crops are best not picked while the leaves are wet: cucurbits (squash, melons and cucumbers) nightshades (tomatoes, peppers, potatoes, eggplants) strawberries and legumes (peas and beans) until the leaves dry, to reduce the spread of disease.

  • Mowing or weed-whacking will be possible before the soil dries enough to till. These are valuable weed control strategies.
  • Flame-weeding is another way to control weeds in some crops if the soil is too wet. One spring we could not hill our potatoes because of all the rain. Although it took a long time, we flamed the weeds in the potato patch, which left it clean enough to hill when the soil water soaked down enough.

Year-Round Hoophouse Book update, Growing for Market, Mother Earth News post

 My upcoming book The Year-Round Hoophouse is being copy-edited this month. I was lucky enough to get the same copy-editor who I worked with on Sustainable Market Farming. Meanwhile the designer is working on the layout design, and a bookmark. I already have the pre-publication postcards to give away at events I attend. See my Events Page for that information.

My hoophouse book will be published November 20, which means it will come off-press (all being well) on October 12. Between now and then, we will finish the copy-edits, proofread for errors, then go back to the designer to enter the corrections (in June). In July the index gets made, by one of the Twin Oaks Indexing crew. That can take three weeks. Then there’s a last check (August) before the book goes off to the printers. The press needs five weeks to turn the book around (September and some of October). Meanwhile the electronic version (Ebook) is prepared.

The foreword will get written, as will those endorsements you see on book covers from well-known people who have been given a copy of the advance page proofs to read. Also happening is a lot of attention to marketing–sending information to the sorts of people who will be interested in the book.


The May issue of Growing for Market is out. The cover article is about wholesaling, by Jed Beach. His purpose is to encourage growers who are dissatisfied with the stiff competition in retail, to look carefully at comparative costs of selling wholesale. Receiving a lower price (wholesale) will not lead to lower income if you costs are considerably lower.

High Mowing Seeds is sponsoring farmer emeritus Ellen Polishuk to travel the country interviewing farmers for a Farmer to Farmer Profile series, which will be featured in Growing for Market each month.  This month her profile is of High Ground Organics in California, just two miles from the ocean. As well as the climate, Ellen tells us about the state laws that require overtime to be paid at 1.5 times the regular wage, and the requirement for wages for agricultural work to line up with other employment and achieve a minimum wage of $15 in six years’ time. This is causing big increases to labor costs. In addition, the national political situation is causing fewer immigrants to reach the farms. Hence, some farmers are selling up. The farmers at High Ground are selling one of their two farms in order to focus on farming one well. Eco-stewardship is an important value.  They are excited about improving at managing people and weeds, transitioning to only organic seeds, and growing strawberries with anaerobic soil disinfestation (ASD).

Photos of all the  farms featured in Profiles are here.

Ellen has written an upcoming book, with Forrest Pritchard, called Start Your Farm.It will be published in September 2018.

Morgan Houk compares a trip to the accountant very favorably with a trip to have teeth pulled. She encourages all farmers to learn from an accountant:

“the financial success of my business is critical in order for me to continue building community and growing healthy food”

 

Kai Hoffman-Krull writes about two no-till methods: tilling with chicken tractors, and occultation (the cumbersome name of a system using impermeable plastic silage covers to kill weeds and cover crops and leave the soil ready-to-use). The main purpose of using no-till methods for Kai is to keep the carbon in the soil, as both social and environmental activism.

Gretel Adams closes this issue with her usual solid information on growing cut flowers, This issue the topics are ranunculus and anemones. As always, the flower photos are mouth-watering.

I have a new blog post on Mother Earth News This one is a tip for repairing pin-holes in garden hoses. Cheap hoses don’t spring pin holes, they just crack up. But if you invest in good quality hoses, eventually they start to develop pin holes. Cutting the hose and inserting a repair connector is unnecessary. You just need a leftover clamp from a repair coupling (I found I had a whole boxful!) and a square of inner tube. Mark the hole before turning off the water. Wrap the rubber inner tube over the hole, then assemble the old clamp over that.


Meanwhile in the garden this week, we have transplanted tomatoes outdoors, as well as the first cucumbers. The first lettuces are almost ready to harvest, just as the last hoophouse lettuce mix is getting less desirable – milky sap, slightly bitter flavor. We’ve planted out six sowings of lettuce so far. We’ve hilled the potatoes and disked lots of areas for sweet corn and  sweet potatoes.

Meanwhile, we have finished transplanting about 90 tomatoes into two beds in our hoophouse and have been rewarded by seeing how much they have grown in just one week. They were really struggling in the greenhouse, where the light wasn’t so good, and it was hard to keep them warm through those cold nights. Two weeks ago I included a photo of a cleared space waiting for a tomato plant. Now we’re there!

A few days ago we transplanted one bed of yellow squash (Gentry), chosen for being fast-maturing, productive and having a good flavor. Also a bed of Spacemaster bush-type slicing cucumbers, among the spinach, peas and baby lettuce mix.

Next will be the peppers. We have flagged the bed at spots 2 feet apart. Today I’ll harvest that lettuce mix around each flag, clearing the way to digging holes and adding compost.

In the photo above you can also see the bubble-foil insulation we have on the north wall. It improves the light back there, as well as keeping in some heat. It’s only the lowest 2 feet of the north wall, and very little direct light comes in there, so we gain much more than we lose. Also see the diagonal tubing we added to strengthen the frame at the west end, which is the direction most of the wind comes from.

At last the lettuce has started to grow! We have been struggling to find enough leafy crops to harvest  a 5 gallon bucket each day. Today I had no trouble finding plenty of baby lettuce, tender young spinach and baby brassica greens for a salad for a hundred people.


The April Growing for Market is out. The lead article, by Josh Volk, gives ideas for upgrading your packing shed or crop clean-up area. It includes a slatted spray table you can build and some natty clip-on fittings (K-ball nozzles) you can install on PVC pipe to give an easy-to-use sprayer wherever you want one. See below – I haven’t tried them myself.Sam Hitchcock Tilton has a profile of Nature’s Pace Organics in Michigan, and their switch from intensive cultivation to permanent cover crops and strip tillage. Liz Martin has written about the advantages of growing pole beans instead of bush beans. She has trialled different kinds to find varieties that have smaller smoother pods (more like bush beans) and likes Emerita, Blue Lake, Matilda and Cobra. Their trellis uses tall T-posts and two pieces of Hortanova netting. They also grow bean seed using this method. I gather they don’t have Mexican bean beetles or many bean diseases, two of the three reasons we gave up on pole beans. The third is our dislike of installing trellises, which only become worthwhile if your plants will stay healthy for the whole season. Thorsten Arnold writes about their co-op rural online farmers market in Ontario, Canada. Todd Coleman describes how to build and install an in-ground greenhouse heating system, and lastly Gretel Adams in Ohio discusses the many decisions behind building a cut flower greenhouse . They chose a tall-wall three-bay gutter-connected plastic structure installed by Yoder’s Produce Supply. This greenhouse has increased production so much that they are moving into shipping nationally through an online store.

Drill a 9/16″ hole and attach to pipe. No threading or nipples required, grips the pipe and the body fits in the 9/16″ hole. Spray is fan-shaped with spray angle of 65° at 40 psi and spray density tapers off toward the outside to permit overlapping of spray patterns.

  • Fiberglass-reinforced polypropylene
  • EPDM O-ring seal & SS spring clip
  • Pressure rating: 100 psi at 175°F
  • Swivel ball allows for 52° total angle of adjustment

Enjoy your spring!

First of all, I’ll get my confession off my chest. A savvy reader spotted an error in my book Sustainable Market Farming: Take a red pen and correct your copy!

In Chapter 20, Sustainable Disease Management, on page 135 I said “Pathogens can infect the seed via several routes . . . Insects that feed on the plant can transfer the disease (striped cucumber beetles vector bacterial wilt, which is caused by Erwinia tracheiphila)”
It is true that striped cucumber beetles vector bacterial wilt, which is caused by Erwinia tracheiphila. It isn’t true that this disease is seed-borne. I don’t know where I got the wrong information from. I don’t yet know of an example of a disease spread by insects that can become seed-borne (that I feel confident about!).
I’ve asked my publishers, New Society, to correct that mistake next time they reprint. I wrote to the attentive reader, thanked her, and asked her for leads on where to find  information about seed-borne diseases brought in initially by insects.

Meanwhile, I can recommend two books on seed growing (that weren’t out when I wrote my book), that contain good information about which diseases are seed-borne. I reviewed the impressive The Organic Seed Grower by John Navazio a while back..

Newer is The Seed Garden: The Art and Practice of Seed Saving from Seed Savers Exchange and the Organic Seed Alliance. Including “advice for the home gardener and the more seasoned horticulturist alike”, this is also a book from people who work growing seeds, and know their stuff. I plan to review it one week soon (when the work pace slows a little!)
If you’re a seed grower, you might want to add one of these to your wish list. Both are beautiful books, as well as clearly written ones.
This year I am not doing quite as much seed growing as some years. For sale, we are growing Carolina Crowder cowpeas in our hoophouse. Click the link to see photos.
For ourselves, we are selecting and saving seed from our Roma tomatoes and Crimson Sweet watermelon, as well as West Indian Gherkins. We are also saving garlic and shallots for replanting.

It’s that time of year when I line up events I’ll be speaking at in the fall and winter (and to some extent, into spring). Here’s my plan so far:

2012-festival-slideshow Friday and Saturday September 11-12 2015
Heritage Harvest Festival, Monticello, Charlottesville, VA.
On Friday, 1.30-2.30pm I will be offering one of the Premium Workshops, Crop Rotations for Vegetables and Cover Crops.
That’s at the Woodland Pavilion, Visitor Center.
Then I will be doing book signing at the tent called The Shop at Monticello (at the Visitor Center), 2.45-3.13pm.
On Saturday I will be offering another premium workshop, Producing Asian Greens. This one is at the Vegetable Garden Tent at the Mountaintop (where most of the Saturday events are). It’s immediately followed by another book-signing, 5.30-6.0pm. The Festival ends at 6pm. All day Saturday is packed with events, and a General Admission ticket will be all you need apart from tickets for premium Workshops.

MENFairLogoThe following weekend, September 18-20, I will be at the Mother Earth News Fair, Seven Springs, Pennsylvania. The schedule is not yet firm, but I will be presenting The Hoophouse in Fall and Winter probably on Friday September 18 4-5pm at the Mother Earth News Stage, and The Hoophouse in Spring and Summer on Saturday September 19 10-11am at the GRIT stage.

I will also be signing books at the Mother Earth News Bookstore at some point and doing some scale demonstrations of string-weaving for tomatoes at the New Society Publishers booth.

The weekend of October 24-25 I plan to be at the Mother Earth News Fair in Topeka, Kansas with the two Hoophouse workshops. In February 2016, Mother Earth News is running their first fair in Belton, TexasToo soon for detailed information yet, but watch the site, if you live in Texas.


CFSA

November 6-8 I will be at the Carolina Farm Stewardship Association Sustainable Agriculture Conference, in Durham, North Carolina. Click here for the Conference page. I’m doing two workshops, Cold-Hardy Winter Vegetables – on Saturday November7, 8.30-10am, and Succession Plantings for Continuous Harvests – on Sunday November 8, 10.45am-12.15pm. I will also do book signing at the BookSignAGanza, Saturday 5-6pm.


SSAWG

January 27-30 I will be at the Southern Sustainable Agriculture Working Group’s Practical Tools and Solutions for Sustaining Family Farms Conference in Lexington, Kentucky. On the website you can sign up for the e-newsletter and around October 15, you can do Early Bird Registration. I hope to be a speaker, but it’s too soon to say. . .

Books, blogs, conferences and seed-starting

Sales of my book peaked during the holiday season (as also happened last December), so I conclude quite a few growers got a copy as a gift. I hope you are all happy with it! I also noticed that my reviews of Craig LeHoullier’s Epic Tomatoes and Jean-Martin Fortier’s Market Gardener have had a lot of visits, so many gardeners and growers will be curled up with a book, making plans for the next growing season.

I’ve also been catching up on reading, although if I had more time, I could give in to that urge even more! Last week I wrote a post for the Mother Earth News Organic Gardening blog, on Winter Vegetables in Your Hoop House and I firmed up a booking to present 3 workshops at the West Virginia Small Farms Conference February 26-28. On the Friday I’ll be presenting two new workshops back-to-back: winter hoophouse growing and summer hoophouse growing. Of course, I have mentioned these topics in other workshops I’ve presented. The winter crops feature in Cold Hardy Winter Vegetables (click the link to watch the slideshow). I won’t be presenting that workshop at Charleston (the WVSFC site) despite what I said a couple of weeks ago!

The summer crops featured in a presentation I gave at the Southern Sustainable Agriculture Working Group ConferencePractical Tools and Solutions for Sustaining Family Farms.” This year it’s January 14-17, 2015, in Mobile, Alabama. I wish I was going, but I decided it was too far away this year. I intend to go in 2016, when I hope it will be nearer Virginia. My summer hoophouse crops workshop for SSAWG was way back in 2009, before I really got to grips with slideshows! And now I have a lot more photos than I did then! And at WVSFC my Saturday workshop will be the ever-popular Succession Planting for Continuous Vegetable Harvests.

Meanwhile, this week in the garden, I have been taking my turn with the other crew members to harvest for our 100 community members. It takes about 3 hours each day to haul in enough fresh veggies for the masses. Outdoors we have kale, spinach, collards, leeks, cabbage and still some senposai, and the last dregs of celery and lettuce. The chard and the scallions have given up for now. Not dead, just resting. In the hoophouse we are harvesting salad mix, which includes some combination of baby lettuce mix, spinach, mizuna, Ruby Streaks, Bulls Blood beets, Tokyo bekana, Bright Lights chard and arugula). Each harvester gets to customize the mix as they like, so we don’t get the same thing every day.

We are also harvesting pak choy and Napa Chinese cabbage as well as baby turnips and turnip greens, radishes, tatsoi, Yukina savoy, and spinach for cooking. We are leaving the kale and the lettuce heads for later, when we have fewer other crops available (or if we are under snow). the hoophouse is a delightful place to work!

Pretty soon we will be dusting off our heat mat, plugging in the germination chambers, tipping the spiders out of the pots and flats and starting our first seedlings of 2015. We usually start with some early cabbage, lettuce, and mini-onions Red Marble in mid January, and follow up with early tomatoes (to plant in the hoophouse) the week after that. At that time we also start kale and spinach, although nowadays we start those in the ground in the hoophouse and move them out to the garden as bare-root transplants.

Sweet potatoes, statistics and inspiration

After a week of drizzle, it finally eased up and we started harvesting our sweet potatoes. I wrote a lot about this topic last year, so I won’t go into many details here. As usual, we set the dug roots in clusters, so we could see which plants yielded most and chose medium-sized roots from those to grow our slips next year. In the picture above, we are crating the sweet potatoes after someone has gone through selecting the seed roots. In the right background you can see our grid-linked solar array. In the left background is our hoophouse, and to the left is our dying last sweet corn planting. We have one last picking today, from the Silver Queen at the far end. We used a low electric fence around this patch to keep the raccoons out, and either it worked, or the beasts didn’t notice this planting. We didn’t get any visits from tigers or elephants either! Also visible in the photo above are remaining bits of the bioplastic biodegradable mulch we used. It’s made from non-GMO corn, and is great for warm-weather loving vining crops.

This year, the Georgia Jet seem more productive than the Beauregard – I think that’s usual. We dug about a third of the crop the first day and got 86 boxes. The second day we had a lot of other harvesting (beans and broccoli being the most time-consuming), so we only dug another 36 boxes. We’re still only 45% of the way down the patch, so we could end up with 250 or more boxes. Probably the yield will taper off closer to the end of the field as the deer were browsing on the vines all summer.

Friday update: Well, we finished harvesting yesterday, and the yield dropped off a lot where the deer had been browsing (memo: fence out the deer in future!) We got a total of 177 boxes of various sizes, perhaps about 3939 pounds, almost two tons. That’s not a record-breaker, but is second best in the past ten years.

Our yearly harvest of sweet potatoes has varied a lot, from 31 boxes (a sad year) to 243 in 2009. An average over ten years of 112 boxes, each weighing perhaps 23 pounds. We grow about 800 row feet. We always hope to have enough to last till the beginning of May, when people start to lose interest in sweet potatoes, and start hoping for tomatoes.

Now I’ve glided smoothly into the statistics section of this post, so I’ll tell you some figures for my book sales while I’m at it. New Society has sold 3320 to mid-September, from a 5000 print run. They say the book is selling well, not many returns. At Twin Oaks we’ve sold 150 of the 250 we bought in February when it came out. I’ve just set up an Author Page at Amazon, so I can tell you they have sold 940 print copies up till 10/6. They also provide me with ranking info (this could get addictive if I let it!) and my book was #40,116 when I looked. That sounds pathetic till you realize that’s out of 8 million titles. Anyway, enough vanity! As far as its usefulness to readers, having an Author Page means that if you go to Amazon, to my book page, and then click on my name, you can read my bio, and see my upcoming events, and get back to this blog.

Getting perspective on the bookselling world, I was encouraged to learn that there is being a resurgence of small booksellers, despite the Big Online One. Here’s a link to the story in the Christian Science Monitor in March this year. I learned about it from Wendy Welch of the Little Bookstore at Big Stone Gap, who I met at the Festival of the Book in Charlottesville. She has written a memoir about her bookstore, called The Little Bookstore of Big Stone Gap, which you can buy via her website, or, I’m sure, at her store.

And now on to this Inspiring story: At the Mother Earth News Fair I met a young woman of 12 who had borrowed my book from her library. She got inspired and decided to start market gardening. She succeeded in clearing $6000 in her first year, when she was 11!

Frost, tomatoes, sun, rain, mistakes and future events

What a week! With the forecast for low temperatures on Sunday and Monday nights this past week, we back-pedaled on our transplanting plans. The tomato plants in our coldframe were very tall. In order to cover them we extended the cold-frame height by balancing plastic crates on top of the blockwork walls. Setting the lids on top of this construction was a bit precarious, but it worked well. Only a few of the taller tomatoes got nipped at the very top on Monday night when the temperature plummeted to 30F. 5/14 is very late for a last frost for us. Our average for the past ten years is 4/30, but in 2009 it was 5/19. In 2011 it was 4/14. Farming is full of surprises!

On Tuesday we started transplanting tomatoes. Hot dry windy weather. On Wednesday 5/15 it reached 90F. On Thursday afternoon we planned to continue the big transplanting of our Roma paste tomatoes. Three rows are in mowed no-till rye, vetch and winter peas cover crop and one row is on black biodegradable plastic mulch. (Here’s an interesting link to a comparison of the two biggest brands of biodegradable plastic mulch. http://extension.udel.edu/ag/files/2012/03/2012DegradableMulchWM.pdf) But Thursday’s shift was inauspicious. We started with only 5 of us (we plan for 7). One person had to leave at 4pm. One person was called away to bale hay. Another person agreed to provide childcare for the person baling hay, from 4-6pm. Then another person started to feel ill, and left the scene. The 3 of us still working at 3pm started to sow our second zucchini and summer squash. We each used two dowels to make holes every 6″ in the biodegradable plastic mulch. We got the holes popped through, but then another community member cycled by and warned us of a strong thunderstorm heading right for us. Discretion being the better part of valor, we retired for a tea-break and to consult the local radar on Wunderground. An intense “red and yellow” storm, not very wide (ie not very long-lasting), was due any minute. Once it started to rain we decided to quit trying to garden for the day. good thing too. We got an inch of rain in an hour. Too bad the soil hadn’t dried out enough for us to do a second hilling of the potatoes before this new rain. or make ridges for sweet potatoes. Now we’ll have to wait another week, during which there is 20-80% chance of some rain every day except Monday, when it is forecast to be foggy. So I’m getting closer to finishing reading my library book. . .

April 2013 Growing for Market

April 2013 Growing for Market

Meanwhile, in the Mental Gardening Department, I found I had made mistakes in my Growing for Market articles on parsnips and fennel, about which plants can cross-pollinate each other. So I wrote an apology and correction. One of these mistakes is in my book. In case you are reading my former, deluded, beliefs, here is the correction: On parsnips, the facts are that parsnips can cross with wild parsnip, but not with carrots or Queen Anne’s Lace, as I wrongly claimed.

On fennel, the facts are that fennel does not cross with anything except other fennel. It is widely said (even by some seed companies!) that dill and fennel cross, and some even describe the terrible flavor of the resulting crosses. Clearly this is a superstitious belief that continues because acting on the belief produces good fennel (or dill) seed. Similar to how someone might snap their fingers to keep away tigers – no tigers – complete success! I’ve long believed dill and fennel crossed. It’s good to know I don’t need to worry about that any more.

This is the first error I’ve found in my book. Soon New Society wants a list of corrections from me, for when they do a reprint. I’ve only found this and one formatting glitch so far. Embarrassing, but I repeat my Mantra for Consolation: “The only people who never make mistakes are those who don’t do anything.” On Monday I did an interview for Lightly on the Ground Radio on wrir.org (Richmond Independent Radio) with Sunny Gardener. I’m learning how to find and download the podcast (so many technical skills to learn!) I’m working on a powerpoint presentation on Planning Fall Vegetable Production, for Virginia State University’s Summer Vegetable and Berry Field Day on June 27 at Randolph Farm. This will lead nicely to my Last Chance Sowings article for the August Growing for Market and a Cold-Hardy Winter Vegetables presentation for the Mother Earth News Fair in September
