NOFA-Mass Annual Winter Conference, January 12-14, 2023

Northeast Organic Farming Association, Massachusetts Chapter.

The Conference will be held at Worcester State University on Saturday January 14 and online Sunday January 15. We encourage you to make the most of the range of possibilities – i.e. tastings in person, international discussions over Zoom, tool modifications, storytelling. Creativity is welcome!

An organic lunch on Saturday is sandwiched by over 40 educational workshops for a full day of learning and socializing.

This is a valuable opportunity for farmers, gardeners, homesteaders, educators, and environmentalists to share resources and ideas to grow our vibrant organic community. We are excited to come together around this winter’s theme, “Cooperative Foodways: Building Our Future Together.”

The conference hosts 40+ workshops and draws hundreds of attendees from throughout the Northeast.

I will be giving a workshop on Crop Planning for Sustainable Vegetable Production

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”

I hope I’ve got all the conversions right.

Upcoming workshops, winter weather, preparing seed orders

First up, note this change of location for my workshop on December 11th. Adrianna Vargo from the Local Food Hub sent this notice of a change of location:

The new location is:
Albemarle County Office Building

1600 5th Street Extended
Charlottesville VA 22902
Other details remain the same:

Secondly, I am planning a workshop with Cindy Connor, author of Grow a Sustainable Diet and Ira Wallace, author of the Timber Press Guide to Vegetable Gardening in the Southeast. It’s at Lynchburg College, in SW Virginia, on Saturday February 15. I’ll give more details once we have them sorted out.

Cindy has written a blog post about Ira Wallace’s new book, Vegetable Gardening in the Southeast. See http://homeplaceearth.wordpress.com/

The weather here has turned wintry. We are bracing for the big ice storm expected Saturday night and Sunday, likely followed by power outages, during which the electric lines-people struggle to restore power over a big area, as this storm looks (on the radar) like it covers a big swath. Here’s the regional radar from Weather Underground this afternoon

In case you couldn’t tell from my slack blogging recently, I’ve been on vacation. My fellow communard, Ezra Freeman, has been tracking the weather here, and reported in his blog on a low of 10F on Saturday 23 November. The previous low had been 18F on November 13, reported to me by Ken Bezilla at Acorn Community and Southern Exposure Seed Exchange. Here are some seasonal photos of our gardens taken by Ezra:

Meanwhile, our garden work turns towards planning for next year. We have done an inventory of our remaining seeds and decided what to keep and what to throw out. Opinions vary a bit about how many years seeds of different vegetables are good for. The fuller story is that storage conditions make a big difference. You can make your own decisions, weighing up the information supplied, your knowledge of how carefully you stored the seeds, the information on each packet about percentage germination when you bought it, and the economic importance to you of that particular crop. If you always transplant lettuce, as I do, you can risk one of your four varieties in that sowing coming up poorly, and just plant out more of the other three if it fails. Many seed catalogs include information about seed longevity, and so does Nancy Bubel in The Seed Starters Handbook. Frank Tozer in The Organic Gardeners Handbook has a table including minimum, average, and maximum.

A simplified version of how long to keep seeds is as follows:

Year of purchase only: Parsnips, Parsley, Salsify, and the even rarer Sea Kale, Scorzonera

2 years: Corn, Peas and Beans of all kinds, Onions, Chives, Okra, Dandelion, Martynia,

3 years: Carrots, Leeks, Asparagus, Turnips, Rutabagas

4 years: Spinach, Peppers, Chard, Pumpkins, Squash, Watermelons, Basil, Artichokes and Cardoons

5 years: most Brassicas, Beets, Tomatoes, Eggplant, Cucumbers, Muskmelons, Celery, Celeriac, Lettuce, Endive, Chicory

Rather than deteriorating with age, some very fresh seed has a dormancy that needs to be overcome by chilling (lettuce).

We are working towards ordering seeds. The catalogs are starting to appear in my mail box. The early bird catches the preferred varieties! The main companies we order from are Fedco, Johnny’s and of course, Southern Exposure Seed Exchange. We like SESE for regionally adapted varieties, Fedco for great prices on bulk sizes, and Johnny’s for some varieties we really like that aren’t available from the other two. If you are ordering from Fedco and don’t yet have my book, they are now selling it at a very decent price (cheaper than signed copies direct from me). If you need to economize, but don’t want to buy from the big online company that doesn’t pay its workers much, try Fedco, who are a co-operative.
