A weed forming a rosette with large, smooth leaves, 6 to 12 inches long, grows in thin areas of the lawn. The leaves are reddish green, with curly and wavy margins. Curly dock is a persistent perennial weed that grows from a large, deep, brownish-yellow taproot. It is found throughout the U.S. and invades thin areas of the lawn.
Hand-digging to remove curly dock is not only time-consuming and tedious, but also impractical because pieces of root left behind will often sprout into new plants.
