Urtica dioica
herbStinging nettle (Urtica dioica) is a fast, rhizome-spreading perennial whose toothed leaves and stems are armed with tiny hollow hairs that sting on contact - a defense that vanishes the moment the leaves are cooked or dried. Beneath that sting it is one of the most nutritious wild greens: the tender spring tops are eaten like spinach, brewed into a deep-green mineral tea, and made into soups and pesto. It grows in dense colonies in rich, damp ground and spreads aggressively by creeping roots, so it is best given its own contained bed. It also hosts the caterpillars of several butterflies.

When to Fertilize

Fertilizer
Compost or nitrogen-rich feed
Nettle wants rich, moist, nitrogen-heavy soil in partial shade, though it tolerates full sun with enough moisture. Start it from surface-sown seed or, more easily, from a root division, but site it carefully: the rhizomes can spread 5 ft or more in a season, so plant it in a contained bed, a buried bottomless pot, or a corner edged with a 12-in.-deep barrier. Keep it watered for lush, tender growth. Cut it back hard a couple of times a season to force fresh new shoots - the best part for eating - and to keep it from seeding and spreading further. Always wear gloves.

Rinse colonies from the shoot tips; vigorous nettle usually outgrows them
Several butterfly larvae feed on nettle - most gardeners leave them, as the plant regrows fast and supports wildlife
Mainly an issue under cover; keep airflow good and rinse foliage
Harvest the top few inches of tender new growth in spring and after each cut-back, always wearing gloves and using scissors. Pick before the plant flowers, since older flowering nettle develops gritty particles (cystoliths) that are best avoided. Blanch, steam, saute, or dry the leaves immediately - cooking or drying completely neutralizes the sting - then use like spinach or for tea. Never eat the leaves raw.
Cooked nettle is exceptionally nutritious - very high in iron, calcium, and vitamins A and C - with a rich, deep flavor like a more intense spinach, used in soups, purees, pesto, and as a cooked green. Dried nettle also makes a mineral-rich herbal tea. All culinary use requires cooking or drying first to remove the sting.
Wear gloves to harvest - raw nettle stings on contact. Always cook or dry the leaves before eating, which completely removes the sting; never eat them raw.
