Big-Sting Nettle is commonly found in moist, fertile soils and is often associated with disturbed areas such as forest edges, stream banks, and abandoned fields. It prefers partial to full sunlight and can tolerate a wide range of environmental conditions, including both wet and dry soils. The plant is often found in temperate regions and is well adapted to cooler climates, though it can also grow in subtropical areas. Its widespread distribution is partly due to its ability to colonize disturbed habitats and its high seed production.

Urtica dioica is relatively easy to cultivate and can be grown from seeds or by dividing the rootstock. It prefers rich, moist soil and partial to full sun.
