(Lamium amplexicaule)
This weed, also known as dead nettle or bee nettle, is found in lawns and flower and vegetable gardens across the country. It is a winter annual that sprouts from seeds in September and grows rapidly in the fall and the following spring. Henbit also reproduces by stems that root easily wherever the stem joints touch the soil. Henbit most frequently invades thin areas in lawns with rich soil.
Treat the lawn with an herbicide containing 2,4-D in early spring when henbit is growing most rapidly. Do not water for 24 hours after treating. A few small plants can be hand pulled.
