Spacing / density
60 to 120 cm (24 to 48 in)
Germination temperature18 to 22°C (64 to 72°F)
Germination time15 to 20 days
Propagation
Propagate by seed or by underground rhizomes, which allow the plant to gradually form natural colonies. This spreading habit makes it especially valuable for woodland naturalization.
Growing
method
method
Sow Wood Nettle seeds in autumn or spring after a period of cold stratification to improve germination. Surface sow or cover the seeds with no more than 3 mm (0.1 in) of growing medium. Maintain temperatures between 18 and 22°C (64 to 72°F) with consistent moisture until germination, which generally occurs within 15 to 20 days. Young plants thrive in rich, humus-rich soil and partial shade. Once established, this vigorous native perennial gradually forms dense colonies ideally suited to woodland gardens, riparian plantings, and ecological restoration.
Soil
and care
and care
ExposurePartial shade
Soil
Rich, humus-rich, cool, well-drained soil. This species thrives in woodland soils rich in organic matter that remain cool throughout the growing season.
Soil pHAcidic to neutral
Watering
Water regularly to maintain rich, cool, humus-rich soil. This species performs best where soil moisture remains consistently high.
Fertilization
An annual application of compost or leaf mold in spring is generally sufficient to maintain vigorous growth. Chemical fertilizers are rarely needed in organic-rich woodland soils.
Care levelModerate
In spring, remove the previous year's stems and apply a layer of compost or decomposed leaves to recreate natural woodland conditions. During summer, maintain consistent soil moisture, especially during dry periods. This species gradually spreads by rhizomes to form attractive colonies. In autumn, allow some foliage to decompose naturally, enriching the soil. Once established in a suitable habitat, Wood Nettle requires very little maintenance.

Recommended pot size
30 to 40 L (8 to 10 gal)
Wood Nettle can be grown in containers, although a deep pot of at least 30 L (8 gal) is recommended to support its vigorous growth. Use a rich, organic growing medium that remains cool and evenly moist without becoming waterlogged. Place the container in partial shade to reproduce its natural woodland habitat. Growing in containers is an effective way to enjoy this native edible plant while limiting its natural spread.

Recipe
and inspiration
and inspiration
Young shoots and leaves of Wood Nettle are edible when harvested before flowering and then cooked or dried to neutralize their stinging hairs. They are traditionally used in soups, stews, pestos, and herbal teas and provide an excellent source of nutrients. Like other nettles, they lose their stinging properties after cooking or drying. This native perennial also has a long history of traditional medicinal use throughout North America.
