Easily recognizable by its yellow flower, white puffy seed head and distinct, jagged leaves. It is a typical broadleaf weed. See botanical illustration.
Emergence occurs in early spring with continuous flowering beginning several weeks later. Dandelions reproduce from a taproot or by seed. This perennial weed will germinate from seed all season long and can be very persistent and competitive in a lawn. Dandelions can grow in most conditions and soil-types.
Dandelions thrive in thin, weak turf so providing conditions favorable to turf growth is the best way to naturally control them. If they have gone to seed, collect lawn clippings to prevent spreading. In order to successfully dig them out, the majority of the root must be removed.
Spot treat with an herbicide containing triclopyr or a mix of MCPP, 2,4-D, and dicamba. For most effective control, treat early in spring before the first generation goes to seed, . Continue to spot spray as needed throughout the season.
