Problem: Curly Dock
Rumex crispus Curly dock is a persistent perennial weed that grows from a large, deep, brownish yellow taproot. It is found throughout the United States. It reproduces by seeds and invades thin areas of the lawn. Because frequent mowing cuts off the flower stalk, curly dock seldom flowers when growing in 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.
