Urtica dioica, commonly called stinging nettle, is a vigorous, rhizomatous perennial herb in the nettle family (Urticaceae). Native throughout Europe, temperate Asia, and North Africa, it is now naturalized across much of the world wherever soils are moist and nutrient-rich. Plants typically reach 0.6–1.5 m (occasionally 2 m), with opposite, serrated, cordate leaves and fine, silica-tipped stinging hairs (trichomes). These trichomes inject irritant compounds—histamine, acetylcholine, serotonin, and organic acids—causing a transient burning rash on contact. The species is dioecious, bearing separate male and female plants with drooping, greenish, wind-pollinated inflorescences from late spring into autumn. Ecologically, nettles are indicators of fertile sites and support numerous insects, including as a larval host for several butterflies. Despite their sting, young shoots and leaves are highly nutritious when cooked or dried and are used as a vegetable, tea, and in traditional medicine; stem fibers have historic textile uses. In cultivation, nettles are easy and fast, spreading aggressively by rhizomes and seed. Contain with barriers or grow in containers where spread is undesirable, handle with protective gloves, and maintain steady moisture for lush growth.

How to care for Stinging nettle
Water
Keep soil consistently moist but not waterlogged. In-ground plants require roughly 2.5–3.5 cm of water per week from rain and irrigation, adjusted for heat, wind, and soil texture. Use 5–7 cm of organic mulch (compost or leaf mold) to conserve moisture and moderate temperature. For containers, water thoroughly until excess drains, then allow the top 2–3 cm to dry slightly before watering again; ensure free drainage and never leave pots standing in saucers. Reduce watering significantly during winter dormancy, resuming regular moisture with spring regrowth.
Light
Full sun to partial shade. In cool, moist regions, full sun maximizes biomass and seed production. In warmer or drier climates, give morning sun with dappled or afternoon shade to prevent heat stress and keep leaves tender. Deep shade reduces vigor and leaf density, while intense, exposed sun combined with low moisture toughens foliage and can intensify sting. Indoors, provide very bright indirect light (south or east exposure) with good airflow, and rotate pots regularly for even, upright growth.
Nutrients
Stinging nettle thrives in humus-rich, nitrogen-available soils and generally needs modest supplemental feeding. Before planting or in early spring, incorporate 2–5 cm of well-rotted compost or aged manure; side-dress midseason if growth slows. In containers, use a peat-free, compost-amended mix and feed monthly with a diluted, balanced organic fertilizer (around 5-5-5) or fish/seaweed emulsion. Avoid heavy applications of high-salt, high-nitrogen fertilizers that can scorch roots and increase nitrate accumulation in leaves. Stop fertilizing late in the season to prevent overly soft, frost-prone growth.
Temperature
Urtica dioica is very hardy, overwintering to about −30 °C (USDA Zones 3–9/10, depending on provenance). Optimal growth occurs at 15–25 °C with steady moisture. Plants tolerate light to hard frosts and typically die back in winter, re-sprouting from rhizomes in spring. Prolonged heat above 30 °C, especially with dry wind, reduces leaf quality and yield; provide shade and consistent moisture in hot climates. Protect tender new shoots from late freezes if you are cultivating for culinary use to preserve texture and flavor.
