Failed Experiment: Bermuda Buttercup or Sour Grass (Oxalis pes-caprae) as Dye

The “dyed” t-shirt is on the left. The shirt on the right is a basic white tee. I could have achieved similar results by entropy alone.

Chalk this one up to the failures column. In an attempt to use Bermuda Buttercup (aka Sour Grass) and various mordants to dye a couple of white t-shirts yellow and green, I succeeded in dyeing both snowy white shirts a pale shade of …let’s call it ecru. Let’s not call it “grimy old t-shirt white.”

There was a moment last night when one shirt took on an extremely light, delicate yellow-green cast–and that was exciting– but the color came out when I hand washed and rinsed the shirts.

Perhaps it was a half-assed project all along. I had no burning reason to dye with Oxalis–except that it’s thick on the ground right now. Also, Oxalis is rich in oxalic acid, which is supposed to (cough) serve as a built in mordant, helping the plant dye to bind more easily to both plant and animal fibers. Oxalis theoretically yields tones ranging from lightest yellow to a sort of acid green, depending on which additional mordants you might use. Used straight, it was supposed to yield a very pale yellow.

So I thought, why not play with it and see what happens?

My only information source for this project was The Handbook of Natural Plant Dyes by Sasha Duerr. This, also, was a mistake. I usually use more sources when I start a project, but I felt lazy.

I don’t know if this is a flawed book or not–I’m not judging yet. It’s on probation. It’s a pretty book, and inspirational in that it makes you want to dye everything you can lay your hands on–hell it makes you want to raise your own sheep and spin your own yarn, so you can dip it in acorn, cabbage and fennel dye, sing some folk songs, dance a dance,  compost the solids and acidify your garden soil.with the spent dye.

It sent me into fantasies of living in some groovy Sonoma-Portlandish nirvana where my house is clean and has plaster walls and wood beams in the ceiling (the wood beams are always in the fantasy) and a fire in the grate. I’d watch the goats graze in the back yard while I cheerfully sip tea and knit something marvelous out of hand spun angora dyed with Oxalis.

(As opposed to the reality of me stumbling around our money pit of house in my exceedingly unnatural and ancient polar fleece robe, desperately searching for a chair to sit on that doesn’t hold a cat, so I can watch the LAPD stalking around the unoccupied house across the street, guns drawn, trying to nab arsonist squatters, without being in the line of fire. True story! Just happened!)

ANYWAY. Point is, the book did not serve me well in the matter of Burmuda Buttercup.

This is, therefore, an anti-project post. Following these steps will get you nowhere.

A more determined dyer or a better blogger might soldier on and find the correct answers and report them to you as a public service, but I’m sorry my friends.  I’m giving up on this one and will probably try onion skin next.

Read on if you dare.

Nesting Box Plans in SketchUp

SketchUp is a free and easy to use 3D modeling program. And users have created a library of 3D models you can download. Up until recently most of these models were not particularly useful to DIY urban homesteady types. Enter SketchUp model contributor Rick whose collection of models includes the chicken nesting box above, raised garden beds and a couple of other useful projects.

I’m really looking forward to seeing more open source project models like this and hope to contribute some myself. If you know of any other useful 3D models, leave a comment.

Nasturtium Powder

Around this time of year Nasturtium becomes a kind of massive monocrop in our yard. We’re always trying to figure out uses for it. Of course it does well in salads, both the greens and the flowers, and we’ve made capers of the pods. Also, the flowers make a particularly beautiful pesto. But this year, inspired by the culinary experiments of forager Pascal Baudar and his partner Mia Wasilevich (friend them in Facebook if you want a daily dose of foraging greatness) I decided to make a nasturtium powder. It’s simple:

  1. Dry the leaves. Here’s a fast way: take a bunch of nasturtium leaves and spread them in a single layer between two paper towels. Microwave for two minutes.  Or use more conventional methods. Just don’t let them get so dry they lose color. (Important note from Mrs. Homegrown: Careful with this microwave trick! It’s a new one for us. It worked perfectly for Erik when he dried a whole bunch of leaves, but today I tried to dry just one leaf, a celery leaf, as an experiment and it burst into flame after about 30 seconds. Scary!!!!! We think it success has to do with mass and moisture: lots of leaves, not just one.)
  2. Put the dried leaves in a spice mill or coffee grinder and pulse until ground.

Think of nasturtium dust as a kind of zombie apocalypse pepper replacement. Or as a salad dressing ingredient. It is surprisingly tasty–better than fresh nasturtium, and without that bite. It would be fantastic combined with a little good salt. We’re still trying to figure out exactly how to use this magic powder. We may just keep it on the table and sprinkle it on everything.

What do you like to use nasturtium for?

Easing the Pain of Runner’s Knee

Salvation in foam.

Update 4/20/13: Foam rollers can be useful, but you need to be careful. I believe that overuse of a foam roller caused a nerve entrapment issue that has resulted in some numbness to my right shin. Before using a roller I strongly advice reading Foam Roller–Friend or Foe, a blog post by manual trainer Adam Mentzell. Mentzell goes over possible unintended consequences as well as some common sense rules for using a foam roller.

First off, many thanks for all the suggestions Root Simple readers sent in when I asked for help fixing my runner’s knee (in my case caused by fencing). The comment thread on that post is now, I believe, a very useful resource for dealing with runner’s knee thanks to your contributions.

While I still have a lot of strengthening to do to fix the underlying causes of my runner’s knee, the pain is almost completely gone. Several things helped. First off was rest as suggested by my doctor. Rest does not mean taking long walks (for a person like me, addicted to cardiovascular exercise, walking seems like rest). Rest means, well, actually resting. It means taking the elevator or, as my doctor put it, “not being a hero” when going up and down stairs.

But the real miracle came in the form of a foam roller. Several commentators mentioned it and my friend Elon Schoenholz actually came over with one to show me how to use it. At first I was afraid that it would make the pain worse. But out of desperation I finally decided to give it a try. After two short sessions over the course of three days 95% of the pain went away. As several commentators mentioned, using it is pure torture. But I can’t believe how quickly it worked. A commenter left a link to this video, which shows how to use a roller.

The “RumbleRoller.” Ouch!

I found a tight knot of pain and tension in the iliotibial band (ITB) just above the knee. Rolling this spot, carefully at first, loosened the ITB and, I believe, eased the pain. Elon, in dealing with his knee pain odyssey, has moved on to a more intense RumbleRoller

But my work fixing my patella femoral syndrome is far from complete. I’ve got a lot of strengthening and flexibility work to do. To that end I’ve signed up again at my local YMCA. I had let my membership lapse thinking that I could do weight training at home and save some money. This was foolish. It’s hard, with a home gym, to do lower body exercises. While some people probably do fine hefting logs in the great outdoors, I need the structure and motivation that a gym provides. Plus I really like the mission and ethos of the YMCA.

To sum up these are the four steps that helped with my patella femoral syndrome:

  • rest
  • weight training
  • foam rolling the iliotibial band
  • gym membership

I have a feeling I’ll be running and fencing again soon.

Picture Sundays: A Handy Handyman

Kelly found a soggy flyer on a sidewalk near our house. The front showed a picture of a man with a mullet hairstyle holding a trophy below a headline “Best Handyman.” On the back said handyman promised the services you can see above. I laughed, then realized that it was my exact jack-of-all-trades-master-of-none set of skills. Well, except for “hydrophany” and gutters. And you’ll have to go to Kelly for both the fine art and the house painting.
