Monthly Tip

Burning & Stinging Nettles

Tip description

Our gardens are pleasant places but not if you find burning nettle (Urtica urens) or stinging nettle (Urtica dioica) among your flowers or vegetables. You’ll know they are there if you brush against them and immediately feel a burning or stinging sensation. Leaves and stems are covered with hair-like tubes that inject an irritating substance when touched. Look for them in late fall and early spring. Remove them as soon as they appear, using gloves for protection. They can produce viable seeds in just five weeks and produce 1,500 seeds per plant. A thick layer of mulch or cover crops with dense canopies can help suppress germination.
