Growing
Stinging nettle prefers rich soil and consistent moisture. Providing mulch around the plant will help retain moisture. Nettle can become invasive if not managed. To prevent spreading it can be kept in check by removing the flowers as they appear to prevent self-seeding. Regular harvesting will also keep the plants under control. It can also be grown in containers. At the end of the season, the leaves and stems make a good nitrogen-rich addition to compost.
Harvest
Pick tops of plants before they flower when leaves are young and tender. Harvest no more than a third of the plant at a time.
