Henbit and Chickweed
Henbit and chickweed are winter annual type plants. This means they germinate in the fall or late winter. They generally bloom in the spring, produce seed and then the plants die.
Henbit grows upright and has leaves with scalloped shaped edges and the leaves will be opposite of each other on a square shaped stem. Some may bloom in the fall, but most plants will bloom in late winter or early spring. The flowers have lavender to blue color.
Chickweed is a low growing plant with creeping type stems. It has a delicate appearance and may stay green most of the year during mild weather. The leaves are oval shaped and are spaced opposite of each other on the stem. The plants produce a small star shaped flower. Chickweed is most often found in shady areas under trees and shrubs and on the north side of buildings.
For effective control of weeds, identify the plant. Look through books and guides to help you. Or take a sample to your county Extension office, master gardener office or garden center for identification.
A good thick stand of grass will discourage henbit and chickweed from growing in your lawn. You can use a preemergent herbicide such as Gallery in late September. After the plants germinate and are growing a three-way premix herbicide such as Trimec can be applied in the fall or early spring on a warm day. Follow directions on the herbicide label for application rates and time of application.
