Stinging nettle (Urtica dioica) has been used for hundreds of years to treat painful muscles and joints, eczema, arthritis, gout, and anemia. Today, many people use it to treat urinary problems during the early stages of an enlarged prostate (called benign prostatic hyperplasia or BPH).
GROW: Start seeds inside about four to six weeks prior to the last frost free date for your area. Plant one to three seeds in peat pots filled with potting soil. Lightly cover them with ¼ inch (1.25 cm.) of soil. Keep the growing stinging nettle seeds moist. Germination should occur by about 14 days. You may also direct sow nettle greens in the garden. Choose a spot that has rich, moist soil a little ways from any other herbs. Seed in the spring in rows that are an inch apart and keep the area moist. If you started your nettle inside, transplant the growing nettle greens into a prepared garden bed, spaced at least 12 inches (30 cm.) apart.
HARVEST: Your nettles will be ready to harvest between 80-90 days from seed. The best time to harvest nettles is the first few weeks of spring when the leaves are young and tender. The plant will be under a foot in height. Pick the first two or three pairs of leaves from the top of the plants. You can continue to harvest through the summer, but the stalks and stems will be very fibrous, so just take the top few pairs of leaves. Be sure to wear gloves and lots of clothing. In fact, dress as if you are going into battle before harvesting nettle greens. Otherwise, the tiny hairs will embed themselves into your skin, making life pretty uncomfortable. Those tiny hairs contain several chemicals that cause a burning, stinging feeling that can last for hours. Use sharp scissors or garden shears outside and handle the nettles with tongs in the kitchen. Cooking the nettles will obliterate those pesky hairs.
USE: Stinging nettle has been used for hundreds of years to treat painful muscles and joints, eczema, arthritis, gout, and anemia. Today, many people use it to treat urinary problems during the early stages of an enlarged prostate (called benign prostatic hyperplasia or BPH). Use fresh or dried leaves.
