Perennial weed, thrives in hot, dry weather when turf is stressed. Grows from a large tap-root in mid-spring and grows all season long. Can tolerate low mowing and heavy soils.
Encourage conditions favorable for turf growth including proper drainage and fertility. Can be dug out by hand, but entire tap root must be removed for effective control.
Spot spray with post-emergent broadleaf herbicide containing triclopyr, clopyralid, or 2,4-D, MCPP, and dicamba.
