Japanese Indigo Update

So, my attempts to germinate my own Japanese indigo seeds were futile. I kept scrutinizing the tiny little green things that were growing, but none of them seemed quite right. Not pink or plump enough. Eventually I gave up.

Jeff Silberman and Carolyn Wetzel to the rescue! Jeff has been growing Japanese indigo for several years as part of a sustainability project at FIT. Carolyn was driving down to Pennsylvania to teach a lace-making class. Wearing her New England Flax and Linen Study Group hat, she was also dropping off a custom-made flax brake for Jeff made by her neighbor. Gotta love the incredible skills and social networks of the Western MA hilltowns! On her return trip, Carolyn picked up some seedlings for me and dropped them off at our apartment.

At first I was puzzled and a bit dismayed. Dozens of teensy seedlings were crammed tightly together.

I conferred with Jeff. He said that they were very hardy and resilient, and could stand quite a bit of disruption. I used a plastic knife to separate a few at a time.

On June 15th I transplanted them into small pots. I regretted the violence done to the roots. I was literally tugging teensy roots apart with my hands. But after my over-crowded flax experience, I figured it was better to give them room to grow.

I was worried that they would all die of shock. The next morning, though, they looked fine. Here they are on June 16th:

Behind our apartment there is quite a bit of squirrel action. They run amok and tend to knock things over and dig things up, including the Japanese indigo seedlings. So, on June 19th I covered the seedlings with plastic covers in an attempt to protect them. Sammycat inspected and approved the set-up.

I also sprinkled red pepper flakes around the plants. The squirrels had been digging and we hoped that the capsaicin would dissuade them. All the plants got the same treatment (we also grow tomatillos, chili peppers, and a bunch of other plants). It mostly worked. This plant wasn’t so lucky:

Here’s a closer view of some of the other Japanese indigo plants:

I guess I didn’t do any further photo-documentation until they were ready to transplant into the garden bed. The bed I was planning to use had been occupied all spring by the second year woad plants that were going to seed. On July 4th the woad seeds were ripe. I harvested them and cleared the bed for a new crop.

Here are most of the transplanted Japanese indigo plants on July 7th:

Here’s a ground-level view:

There have been a lot of rabbits this year. This photo is from our school garden, but I’m including it because I didn’t manage to photograph the rabbit at Bramble Hill.

The very day that I transplanted the Japanese indigo seedlings, I arrived at the garden to find a rabbit sitting right in the midst of everything! Now, the bunny at the school garden was rightfully scared and hid under the platform.

Not so the bunny at the Bramble Hill Farm plot. Instead of running away like a small creature might normally do when a human comes along, it just shuffled over and settled down under the amsonia like it lived there or something. Cheeky rabbit.

So, I figured I needed to protect the seedlings from chewing. Here was my first effort on July 7th:It was enough to discourage the rabbits, thankfully, but I tightened things up on July 8th:

Eventually we had a hot spell, on top of a long dry spell. At first I left on the row covers thinking it would provide a bit of shade. But on July 18th I figured the time had come to uncover the plants and let them take their chances with the rabbits:

On July 18th the seedlings were looking great:

The rain barrel got low, so I had to deliver water via car, but on July 20th, despite the hot spell, they were thriving. Yesterday, July 22nd, we had heavy rain. The rain barrel is full again. I am optimistic about continued health and growth.

Japanese Indigo Seeds 2019

Back in April I cleaned up some Japanese indigo seeds from plants I grew in 2017.

Here’s the little bag I stored them in as I cleaned them:

On April 7th I put them inside damp paper towels to sprout, as I’ve done before. You can read about earlier Japanese indigo sprouting efforts in my earlier posts here and here.

Here’s what one hundred Japanese indigo seeds looks like:

From what I’ve read and experienced, Japanese indigo seeds do not stay viable for long. You’re supposed to use them in the next growing season. if you try to store them longer than that, expect poor results. Since I do not plant Japanese indigo every year, my germination rate is always pretty low. I set up a sheet with 100 seeds to make the math easy.

This year I bought a seedling mat to keep them warm. I thought it might help with germination. Here’s the type I bought:

Here’s how I set it up:

The mat certainly worked to keep things toasty. In fact, I added a towel on top of the mat to keep the seeds off the direct heat. But as it turned out, I got way too impatient to wait for the seeds to sprout on the paper towels.

Japanese Indigo August 2017

Way back in August I ran a Japanese indigo vat. Here’s what the bed of Japanese indigo plants looked like on August 20th:

I have only dyed with fresh Japanese indigo leaves a few times, so I am still trying to develop skill with the process. An important part of developing skill is repetition. Another important piece is learning and testing new things, and then trying to understand why they do or don’t work. Luckily, this vat afforded me all of those opportunities!

I picked 22 oz. of plant material, which yielded exactly 1 pound (16 oz.) of leaves trimmed off of the stems. Here are the tips of the plant stalks that I harvested:

On the left are the stems, and on the right is the bag with just the leaves in it. It’s a really beautiful plant! It has sweet little hairs, wrapped-around layers, exciting color contrasts, and an interesting juxtaposition of rigid and luscious textures. Continue reading “Japanese Indigo August 2017”

Testing Japanese Indigo Seed

In 2014 I was very excited to acquire my first Japanese indigo seedlings at the Massachusetts Sheep and Woolcraft Fair in Cummington, MA. I bought them from Blue By Ewe in Temple, New Hampshire. That year I saved the whole crop for seed. You can read about my harvest in an earlier blog post here. I intended to expand the amount I grew each year and save my own seed annually.

I did manage to grow my own seedlings in 2015, which I documented in a couple posts that you can link to here and here. I even managed to use the plants for dyeing that year. However, I was not on the ball to save seed in an organized way that fall, and I did not grow any Japanese indigo in 2016. Continue reading “Testing Japanese Indigo Seed”

Wrapping Up A Loose End

I have not done much dyeing lately. My last dye day was on September 6th when I ran my second Japanese indigo vat. Since then, I managed to rinse and dry the skeins, but didn’t get much further than that. They’ve been sitting in a tub waiting for closure. On New Year’s Eve I finally wrapped up that loose end.

As I noted in my original post, I don’t have good photo-documentation about that vat. But at least now I can show you photos of the skeins I dyed. All the yarns are wool. Here are the blue skeins.

The Hurrier I Go

Life has been very busy. Back in July I kept thinking, “July is the month of everything.” Dye plants blooming, flax needing to be harvested, NEH summer institute, NEWS, family weekend at Queen Lake, hiring a new co-worker at school…. I did a lot, but since I can’t do everything, I had to let a lot of things go. No goldenrod or Queen Anne’s lace dye baths this year, and I missed Peggy Hart‘s talk on the history of NEWS, for example. (12/30/2023 Edited: Here are updated links to the National Endowment for the Humanities Summer Institute and New England Weavers Seminar.)

Then when August came, I thought, “No, August is the month of everything.” Even *more* dye plants blooming, flax *really* needing to be harvested, prepping for school, getting to know my new co-worker….  I did a lot, but ditto July. I had to let a lot of things go. No flax retting experiments. No purple loosestrife or black walnut experiments, despite an absolutely ridiculous abundance of wild dye plants. Very few orange cosmos flowers were collected and frozen. No woad was cut or dyed with. The flax and linen study group website was not updated. Continue reading “The Hurrier I Go”

Japanese Indigo Vat At Last

Last year at the Massachusetts Sheep and Woolcraft Fair I bought several Japanese indigo plants (Polygonum tinctorum, though I’ve heard that perhaps the name has changed). I was very excited and intended to dye with them, but then next thing you know, summer had raced past and they were blooming. I was worried that they would have lost a lot of their color once they started to bloom. And I was worried that I might have a hard time finding plants or seeds again. I decided I’d save them for seed and not use them for dyeing after all. You can recap a couple posts from last year here. And here.

This spring I successfully grew about 40 seedlings, half of which I put in at Bramble Hill Farm and the other half at our community garden plot. I guess I was in a “don’t put your eggs in one basket” mode this spring. Very wise, as it turned out. Continue reading “Japanese Indigo Vat At Last”

Japanese Indigo Take Two

After realizing my mistake with the first attempt at growing Japanese Indigo seedlings, I tried again. On April 25th, I laid out some seeds to sprout in damp paper towels. I’ve used this technique with beans before, but I didn’t think to try it with the Japanese indigo seeds until I heard from Laura Harris, a fellow Seed Savers Exchange member to whom I sent some of my seeds earlier in the spring, that she had done it. And ta da! Success!

Here are a couple photos of the seeds once they germinated.
