Introduction – Edible Nettle, weed or hidden treasure?
“What stung you yesterday could become your ally tomorrow. Nettle is a paradox: unloved and feared, yet also a superfood and organic fertilizer. This guide shows you how to turn a prickly weed into a valuable resource, both in the kitchen and in the garden.”
Why nettle deserves a place in your kitchen and garden
We fear its stings… but nettle (Urtica dioica) is far more than a “weed.” It’s a super-plant that feeds, heals, and fertilizes. In wild cuisine, it transforms into soup, pesto, or omelet rich in nutrients. In the garden, it becomes a formidable organic fertilizer through nettle tea. In short, nettle has two lives: the one that stings… and the one that nourishes.

Nutritional benefits of nettle
A true vitality booster, nettle contains more protein than most leafy greens, as well as exceptional amounts of iron, calcium, magnesium, and vitamins (A, C, K). Its polyphenols and carotenoids make it a powerful natural antioxidant. Eating nettle means boosting your energy and immunity while rediscovering a local, sustainable resource.

Nettle in herbal medicine: uses and limits
In herbal medicine, nettle is valued for its anti-inflammatory, diuretic, and remineralizing properties. It supports vitality and sometimes relieves joint pain. But caution: nettle may interact with certain treatments (anticoagulants, antidiabetics, antihypertensives). It is therefore a complementary ally, to be used with discernment, never as a substitute for medical treatment.

Harvesting and preparing nettle in wild cuisine
Harvesting nettle is a way to reconnect with an ancestral practice. It grows abundantly in rich soils, but the secret lies in how to pick it and what precautions to take to turn a sting into a gastronomic delight.
🔗 France Inter – How to harvest nettle.
When and how to harvest nettle safely
The best time is spring, when young leaves are tender and nutrient-rich. Pick only the top 15–20 cm using gloves and shears. Avoid roadside or treated areas. Above all: respect the “never more than one-third” rule to allow the plant and insects that depend on it to thrive.
Precautions and contraindications
- Always cook, dry or crush before eating, to neutralize the stinging hairs.
- Do not harvest in full bloom: leaves become fibrous and less digestible.
- Caution for people under medical treatment (possible interactions).
- Prefer occasional use or seasonal cures, as with all medicinal plants.

Nettle fertilizer: an essential organic ally
In the garden or on a balcony, nettle fertilizer (nettle tea) is a true ally. Used for generations, it acts as a natural fertilizer rich in nitrogen and minerals, stimulating plant growth and strengthening defenses against pests. Its effectiveness comes from the fermentation of nettle leaves, which releases nutrients and makes them directly available to plants.
Traditional recipe step by step
Making your own nettle tea is simple and economical:
-
- Harvest 1 kg of fresh nettle leaves (before flowering).
- Chop them roughly and place in a non-metallic container.
- Add 10 liters of rainwater (or dechlorinated water).
- Cover partially (allow air circulation) and stir every 2–3 days.
- Let ferment 7 to 15 days, until bubbles stop forming.
- Strain carefully → you get a brown liquid: your fertilizer is ready!
Storage: only a few weeks, in a closed container kept in the dark.

How to dilute and use nettle fertilizer in the garden

- Watering at the base → dilute 1:8 to 1:10, once per week.
- Foliar spray → dilute 1:10, as prevention against aphids and diseases.

Nettle in permaculture: fertilization and biodiversity
In permaculture, every plant has a function. Nettle feeds, protects, and shelters insects. It’s a bridge between human food and soil fertility.
Nettle also helps raise compost temperature quickly. Rich in organic matter, nitrogen, and bacteria,nettle fertilizer stimulates decomposition and microbial life. It is an endless, renewable, free and non-polluting source of fertilizer.
It can be used throughout the growing season as an insecticide, fungicide, or biostimulant (foliar spray).

Nettle fertilizer vs compost: complementary roles
- Compost = background effect, nourishes soil long-term.
- Nettle fertilizer = immediate effect, stimulates growth.
Used together, they form a complete cycle: nutrient reserve + growth boost.
Pairing nettle with other natural fertilizers
- Comfrey tea → promotes flowering and fruiting.
- Horsetail decoction → strengthens defenses against fungal diseases.
- Vermicompost → balances soil biology.
