It’s pesticide season in Glen Canyon Park, with one of the most toxic pesticides in use: Triclopyr. (This is the one that’s brand-named Vastlan.) The target plants are oxalis, as usual! And a new one – Sheep Sorrel. It’s actually an edible plant, sometimes sold in farmers’ markets. Said one of our readers, “You can make a good soup (green borscht) from sheep sorrel – with green onions. Possibly adding spinach and potatoes. (There might be other variations.) One vendor at the Alemany Farmers Market sells sheep sorrel.”

We cannot recommend harvesting sheep sorrel that’s been sprayed with triclopyr!

These pictures were sent to us by a supporter. “FIVE signs in Glen Canyon — there might have been more, but this is what I saw — all in that center part of the park. Here are two photos of each: one distant, and one so you can read the details.”
