Curly dock is a perennial weed with a thick taproot. Leaves grow mostly at the base of the plant and are lance-shaped with wavy or curly margins. Leaf blades are 6 to 8 inches long and 1 to 2 inches wide. The green leaves may be tinged with reddish purple. Curly dock seldom produces seed in maintained turf. When the plants grow unchecked, small greenish flowers are produced in clusters at the top of the main stems. Flowers become reddish-brown at maturity. The shiny, reddish-brown triangular seed is surrounded by three sepals.
Perennial broadleaf turf weeds are capable of living more than two years. They thrive in weak, thin turf; golf fairways and roughs; home lawns; playfields; and industrial grounds. Proper turf maintenance is the key to control of this weed. First, select adapted turfgrass cultivars for your area and then properly fertilize, mow, and water to encourage dense growth.
