Chickweed is a winter annual that germinates in the fall and winter and actively grows in the spring. This weed can be controlled with an application of Lawn Weed Control. Chickweed should be controlled before it flowers. Regular monitoring and removal of plants from the site will prevent seeds from developing.
In lawns, the best way to control it is to maintain a thick, healthy lawn. Deep, infrequent watering also discourages chickweed.
