Stinging Nettles

Quick Weed Facts:
  Small, green heart-shaped, toothed leaves growing in opposite pairs along the stem. Has catkin-type flowers, with leaves and stems covered in ‘hairs’ both stinging and non-stinging.
Colour: Flower Brown/Green Catkin
Family: Urticaceae Genus: Urtica
Main Species: Stinging Nettle (Urtica dioica)
Other Names: Common Nettle, Burn Nettle, Stinging Nettle, Nettle Leaf, Stinger
Most Active Growing: May – September
Weed Type: Perennial

Stinging nettles are hardy perennials that develop into 4-6ft (1.2-2m) tall masses. Stinging nettles are widespread almost everywhere but particularly in Europe, North America, and North Africa.

To avoid the more painful way of identifying stinging nettles (Urtica dioica) when weeding check the stems, which are covered in ‘stinging’ nettle hairs, which make them quickly noticeable; also look for their drooping, brownish-green tassle-like flowers from around May to September, and their oval, toothed green leaves. As a result, stinging nettles are usually considered to be a common UK weed.

With all that said, if you have the room to leave some stinging nettles, they can be a superb food and habitat source for Red Admiral butterflies (Vanessa atalanta) and  the caterpillars of the Small tortoiseshell (Aglais urticae) and Peacock butterflies (Aglais io)

Stinging Nettle Seeds Are The Problem

The stinging nettle (Urtica dioica) is a perennial, herbaceous plant with creeping roots that grow with creeping surface stems that root at the nodes and produce aerial shoots in ‘loose’ new soil that has high phosphate levels.

Nettles are very tolerant of harsh climates, growing readily from seeds. They are either male or female plants, and when both sexes are close, female plants generate a lot of seeds.

How To Get Rid Of Stinging Nettles

Natural Control

If a non-chemical stinging nettle treatment removal method is to be used then it should be implemented in mid-summer, or earlier, but prior to ‘seed fall’ to prevent any future infestations.

Nodes on ‘creeping’ stems should be eliminated to prevent regrowth. Young nettle plants may also be eliminated by vigorous hoeing.

Digging out and removing plants after they’ve been cut down is the ‘optimal’ approach, and their removal using this method may be done at any time of year.

It is however unlikely Perennial nettles will be a persistent problem in regularly cultivated areas, except perhaps where there is a residue of nettle seeds in the soil, or perhaps your cultivated area is adjacent to neglected land.

Chemical Control

This method of control is easily undertaken using a glyphosate-based weedkiller like Roundup Ultra or similar. Killing and clearing stinging nettles this way is not difficult but the application can be tricky.

Non-suckering woody plants, such as shrubs or nettles, can be sprayed with glyphosate as long as the stem/bark is brown and woody. Avoiding leaves and other green parts of all garden plants is necessary when using glyphosate, as it is not selective in action.

Glyphosate does not penetrate the soil, so there is no risk that garden plants absorb it through their roots.

NB: However, it’s important to follow the instructions on the manufacturer’s packaging when using glyphosate-based products.

Use this chemical spray treatment shortly before ‘stinging nettles’ flower around June, another treatment may become necessary in September to be sure. The following March/April check all remaining plants and fork or hoe out residue plants and burn.

Why Do Stinging Nettles Sting

The bulbous tips of the stinging and non-stinging trichomes (plant hairs) on the toothed leaves and stems break off when brushed against, revealing needle-like tubes that puncture the skin.

These tiny hairs contain irritating chemicals, and the plant injects acetylcholine, formic acid, histamine, and serotonin into the body, causing an itchy, burning rash in humans and other animals that may last up to 12-24 hours. The plant defends itself against large herbivores using this defence mechanism.

Stinging Nettle Treatment

It is important to wash the affected area with soap and water to remove the nettle hairs and alleviate any stinging as soon as possible if you are stung. If no water is available, clean the area with a cloth or other similar material. You may ease local itching and swelling by applying a wet cloth or ice pack to the affected area.

It is also crucial to refrain from scratching or rubbing itchy areas.  Antihistamine may help alleviate local itching and swelling, while creams such as hydrocortisone might help reduce inflammation. These creams are available at any local pharmacy.

Stinging Nettle Tea

Stinging nettle tea is prepared by steeping the leaves of the Stinging Nettle (Urtica dioica) in hot water. Vitamins and minerals such as vitamin A, vitamin C, and vitamin K are abundant in this tea.

It is said that the tea infusion in addition to providing potassium, iron, and magnesium, is also beneficial for kidney and prostate conditions. Nettle tea is used to treat urinary tract infections (UTI), kidney, and prostate problems. It promotes good strong urination, which is of course healthy.

How to Make Sting Nettle Tea

  1. Add water to the leaves in a saucepan.
  2. Bring the stinging nettles in the water to the boil.
  3. Turn off the heat and let the mixture stand for five (5) minutes.
  4. Pour the nettle mixture through a small strainer.
  5. Add a bit of honey, cinnamon, or sugar substitute, if you like.

First start out slowly by only having one cup of nettle tea to make sure you don’t have any nasty allergic or other reactions to it. Before proceeding further.


Are Stinging Nettles Poisonous?
