How to Grow Stinging Nettles in Your Garden

Introduction

Stinging nettles (Urtica dioica) are a common wild plant known for the stinging hairs on their leaves and stems that cause an itchy rash when touched. However, they have a long history of being used both medicinally and as a nutritious edible plant. Growing stinging nettles in your garden can provide you with a sustainable source of this versatile plant.

Choosing a Location

Stinging nettles thrive in moist, nitrogen-rich soil. When choosing a location:

  • Select a site with partial to full sun. Nettles prefer at least 4 hours of direct sunlight per day.

  • Pick an area with consistently moist soil. The ideal location will have damp soil without getting waterlogged.

  • Choose a space that has not been treated with chemical fertilizers or pesticides. Stinging nettles grow best in organic soil.

  • Nettles grow well in zones 3-9 so select an outdoor location based on your hardiness zone.

  • Allow at least 2-3 feet spacing between plants for good air circulation.

Obtaining Plants

You can obtain stinging nettle plants in several ways:

  • Collect wild nettle plants. Dig up young nettle plants, being careful to get the roots. Replant them immediately in prepared soil.

  • Purchase seedlings or seeds. Buy from a reputable online herb provider. Select seeds suited to your region.

  • Divide existing plants. If you have nettle plants nearby, divide the roots in early spring or fall. Replant divisions.

Planting Nettles

To plant your stinging nettles:

  • Prepare the soil by mixing in 2-3 inches of compost. Nettles thrive in nitrogen-rich, organic soil.

  • Dig holes that are larger than the root balls of your nettle plants. Space 2-3 feet apart.

  • Carefully place plants in holes and fill with amended soil. Pat down gently but avoid compacting the soil.

  • Water thoroughly after planting. Continue watering 1-2 inches per week until established.

Caring for Nettle Plants

To keep your nettles healthy:

  • Water deeply 1-2 times per week during the first year. Mature plants are drought tolerant.

  • Mulch around plants with 2-3 inches of organic material like wood chips to retain moisture.

  • Fertilize in early spring with a nitrogen-rich organic fertilizer or compost.

  • Pinch off any flowers in the first year to encourage leaf growth.

  • Harvest leaves regularly by pinching off tops to promote regrowth.

  • Divide congested plants every 2-3 years to maintain vigor. Replant divisions promptly.

Pests and Diseases

Stinging nettles are relatively pest and disease free. Potential issues include:

  • Aphids – Control with horticultural oil or insecticidal soap. Avoid excess nitrogen.

  • Leaf spots – Improve air circulation. Remove and destroy infected leaves.

  • Root rot – Allow soil to dry between waterings. Improve drainage.

  • Slugs and snails – Remove by hand or trap. Sprinkling diatomaceous earth can deter them.

Harvesting and Using Nettles

  • Wear gloves and long sleeves when harvesting to avoid stings. Cut no more than 1/3 of plants at a time.

  • To eat, blanch leaves in boiling water for 2-3 minutes to deactivate stinging hairs. The leaves are nutritious cooked greens.

  • Dry leaves out of direct sunlight to retain nutrients. Use dried leaves for teas, tinctures, infused oils, etc.

  • The fibrous stems traditionally were used to make cloth, twine, and paper.
