Urtica dioica
Stinging nettle, great nettle, European nettle, burning nettle: the garden’s most disliked plant is actually one of its most useful. Its stinging hairs are tiny silica ampoules that break on contact—a remarkable defense mechanism that does not prevent it from being cooked or turned into the best free fertilizer for the vegetable garden.
Characteristics:
-
Hardy perennial: a herbaceous plant native to Eurasia, it forms long-lasting colonies through its rhizomes.
-
Triple use: vegetable, liquid fertilizer, and biodiversity refuge.
-
Rich in nitrogen: its nettle tea is a natural fertilizer well known to gardeners.
-
Very easy: it grows on its own; just give it a corner.
Precautions:
- Its stinging hairs cause itching on contact: wear gloves and long sleeves when harvesting and handling it.
- Cooking, drying, or simply passing a rolling pin over it completely destroys its stinging power—once cooked, it no longer stings at all.
- It is spreading: its rhizomes colonize areas quickly. Give it a defined corner rather than a place among your crops.
Sowing advice:
-
Exposure: partial shade to full sun.
-
Soil: rich in organic matter, deep, moist, and well drained. Stinging nettle is a nitrophilous plant: it seeks nitrogen-rich soils, which explains why it grows spontaneously near compost piles and old manure heaps. Its spontaneous presence is also a good indicator of fertility.
-
Method: sow in spring, on the surface or barely covered: its tiny seeds need light. Keep moist until germination. It grows just as well in the ground as in a planter, which makes it easier to contain. See how to sow your seeds.
Care advice:
- None, apart from keeping it contained. Water during dry periods if you want a regular production of tender leaves.
- Cut the clump back after each harvest: it will regrow with younger, more tender shoots.
Harvesting advice:
- Pick the young tips, the first four to six leaves, in spring and after each cutback. Avoid older leaves and plants that have gone to seed, as they are tougher.
- For nettle tea: steep 1 kg of fresh leaves in 10 liters of water for one to two weeks, stirring daily, then filter. Diluted to 10%, use it to water the base of nutrient-hungry crops.
Beneficial combinations:
Benefits for biodiversity:
- It is the exclusive host plant for the caterpillars of several of our most beautiful butterflies: Peacock, Red Admiral, Small Tortoiseshell, and Map. Without nettles, there are no such butterflies—a patch of nettles at the back of the garden is the most effective gesture we can make for them.
- It also shelters specialized aphids and therefore ladybirds, serving as a reservoir for beneficial insects in spring.
Uses:
- Young leaves cooked like spinach, in soup, quiche, pesto, or gnocchi—cooking removes all stinging power. As a fertilizer tea in the vegetable garden.
- Traditional medicinal plant, listed in the French Pharmacopoeia. See our medicinal plants to sow.
Harvesting your own seeds:
Since stinging nettle is dioecious, both male and female plants are needed to obtain seeds. Leave the hanging clusters on the female plants to turn brown, then shake them over a container—with gloves. See how to store your seeds.
Commitment to Quality: at SemiSauvage - Permaculture, we grow and select our seeds with respect for all living things as our guiding principle. Based near the Volcanoes of Auvergne, we choose open-pollinated, non-hybrid varieties, test them for germination rates, and carefully sort and package them without any chemical treatment. Our conviction: to give gardeners back the ability to resow, year after year, seeds that truly belong to them.
The much-maligned plant that feeds your plants, your butterflies, and your soups.
