Curly dock is a perennial broadleaf weed. It is commonly found throughout the United States.
It has a bright, shiny green, lance-shaped leaves that appear in the spring. In the summer and fall, the wavy puckered edges of the leaves are tinted a reddish purple. Small greenish flowers appear on a tall, narrow spike that arises from the center of the plant.
Curly dock has a large brownish taproot, that grows most actively during the same period as when grass is suffering from the stress of hot, dry weather.
Spot treat individual curly dock plants with a post emergence herbicide containing triclopyr or triclopyr + clopyralid, or one with 2,4-D, or mecoprop + 2,4-D + dicamba.
Curly dock can be pulled by hand or dug up with a small space. Remove all pieces of the root or it will re-sprout.
