In 2019, planted a 10 x 10 plot of flax as part of a longterm project to weave a sail. I am starting from a very soft learning space so the number of steps ahead is huge. This project is both a work in progress and being written up as I have time. Sections with bold headers are typed up.

Growing Flax 2019
Bob built two 10′ x 10′ garden boxes in 2019, but I had a thought. How many tomatoes can one household eat? The second box was a natural place to test out growing flax. The seeds came from the Landis Valley Museum on Pennsylvania which sent me “Lisette” variety (Sourced from Holland.) https://www.landisvalleymuseum.org/
The pictures below are from the 2019 flax patch. I will use the same seed for 2021. Don’t look at the date on the bag. They were past their sell-by, but so am I! At least the seeds were kept cool and dry!
I’d been warned that before planting, make sure the seeds are a fiber variety instead of an oil seed plant! Check. Got that right. Then, if you think you’ll need it, make sure you create a garden with some cross support for the plants. Oops…
The plants grow 3′ tall or more and support each other in the bed. Everything looked good, so I didn’t put in strings to support the plants. We had an early summer hail & wind storm that knocked down most of the bed. I also had some happy pets sleeping in the flax. My 2021 crop will have cross stringing just in case!
After planting there wasn’t much need for weeding. Mainly, I needed patience. I waited. And waited. And watched the stalks get taller and taller. Eventually beautiful blue flowers appeared. Then the seed heads started to form. For finer flax, harvest earlier- general wisdom says when the plant has turned yellow somewhere between 1/2 and 2/3rds of the way up the stalk. For 2019, I wanted the seeds, so I waited for the seed heads to fully develop.
Fun Historical Fact: The American colonies grew flax for both the seed and the fiber. They sold much of the seed to England and Ireland which allowed growers there to harvest before the seeds fully developed- which meant the fiber harvested there was finer, and by extension, the cloth made was softer and finer than the rougher cloth available in the colonies. (link to more about this at the Encyclopedia of Greater Philadelphia)
Not the greatest photo, but the bottom 2/3-3/4 of the stalks have turned a greenish yellow. The seed heads are nice and plump, and some have started to dry on the plant. That’s a bit too long, but I went to an Irish music festival instead of tending my gardens.
I pulled up the flax, roots and all. I tried making towers, but Fergie the dog couldn’t help but knock them over. I lashed them to the fence for a while until the bundles were mostly dry. I’m on the southeastern shore of Lake Ontario, so mostly dry is the best I could hope for. At last, we got one of those super hot, dry spells. I laid out the flax behind a temporary fence and let the sun bake things for a while.
It seems like this should be the end of it, right. Yay, I have flax. Nope. We’re barely getting started! The next step was taking off the seed heads. I used a fiber hackle which did a great job.
I waited for a windy day which made life easier. A lot of the waste blew away as I pulled the tops of the plants through the hackle. Then I gathered up the seed heads, rolled them between my palms and let the wind carry away the chaff.
I put the seeds in a ziplock for the next garden and then, sadly- but probably predictably-, lost the bag of seeds while moving my studio. Fortunately, I have plenty of seeds left from the first planting. I’m sure I’ll find the 2019 seeds in time for the 2022 planting!
Next Step: Retting
I would have loved to dew ret but it was approaching the end of September and starting to get nippy at nights. So, I pulled out what we call “the Coffin” It’s a big black wheelie box that usually holds stuff in the garage. Now it’s my flax bin. It’s a fabulous flax retting bin because it is over 4 feet long and gets nice and hot in the sun.
Writing this makes it all sound very seamless. Not so. Here’s how things go:
Figuring out when to stop retting is hard for me. I was trying to keep the lid on the box as much as possible because the black top helped keep the water up to a good retting temperature. After the first week, I checked the retting progress every afternoon. I should have split up the flax into two batches because the flax retted at different rates. The books and articles say that the thicker flax should ret faster than thinner because there is more material to feed the retting organisms. I found my thin flax retted faster. My best guess is the thicker flax provided the good growing environment, so the thinner flax was able to ret more quickly. A few articles talk about the final fiber and the organisms involved in retting reflecting the ecosystem which grows the flax. I love the idea that flax has terroir like wines.
Once it was retted, I laid the flax in the yard to dry, and then put it back into the coffin until I had time to build a flax brake. Life got strange, and the COVID pandemic put a spike in my plans to process the flax in 2020. So, here we are- 2021. I finally had time and energy to build some tools. Building a Flax Brake will take you to the plans and step by step directions.
Have you noticed there hasn’t been any talk about weaving a sail yet? It’s coming! There will be a sail!
But first, grow more flax!
Growing Flax 2021
Flax patch 2021 had a rough start. Shortly after I sowed the seed, a thunderstorm dumped over an inch of rain, left divots in the soil, and knocked my carefully strewn seed all over. It happens. I threw a bit more seed at the bald spots and waited for germination…. and waited…. and waited. Our temps were all over the place- 40s up to 90s and back down again. Then the real rain started. Build an ark kind of rain that went on for ages.
Below is a video of the flax going from seed to harvest in 2:33. I pulled the flax at 90 days- just as the earliest seeds were maturing.
Here’s a slideshow of the flax being prepared for retting. I dried my flax for a while because it was going to be a week or two until I had time to oversee the retting. You can go straight to dew retting or tank retting if you are ready. I would remove the seeds from the plants before tank retting if you want to use them to plant the next crop.
The first two days were mid 70s during the day and 60s at night. With the rain, temps have dropped into the 60s with prediction of mid 50’s at night. This may take a little longer than I’d hoped. I pulled back the sheeting so the rain could top up the water level in the retting pool. The foam on the top of the water is a sign of fermentation taking place which means the microbial colonies that will break down the pectin have formed. Now, I just have to give them time. I’m going to ret further than I did last time. Everything I read talked about the dangers of overretting- and they are real! I can always double ret if I find I didn’t let things process enough the first time. To double ret, I can either put the flax back in the pool- or I can follow up the pool retting with dew retting. Our temperatures drop pretty quickly once October rolls in, so it will be better to get things right the first time.
