Feel free to substitute with lambs quarters, dandelion greens, young curly dock, or combine wild greens of your choice. Once they are older and have flowered or set bud they will be bitter. Make sure you have correctly identified your wild greens. If using nettles - with gloves on, place leaves that have carefully been removed from stems, in a pot of salted, boiling water for about 15 seconds. Drain and submerge the leaves in cold ice water, “shocking” them to keep the beautiful green color. Drain and squeeze dry. Coarsely chop. The remaining cooking water makes a nice drink for your plants once cooled.
