Dandelion

Dandelion is one of the most recognizable and widespread broadleaf weeds in lawns, landscapes, and turf areas. While some view its yellow flowers as cheerful, it’s a persistent perennial that can quickly take over thin or stressed turf. Its deep taproot makes it difficult to eradicate, and its fluffy seed heads easily spread through wind, allowing rapid re-establishment across large areas.

How to Identify

Dandelion grows as a low rosette of jagged, deeply toothed leaves that emerge from a thick central taproot. The bright yellow flowers bloom on hollow stems and eventually transform into the familiar round white seed heads that disperse easily in the wind. When broken, the stems release a milky sap.

Lifecycle

Dandelion is a perennial weed that survives year-round through its taproot. New leaves and flowers emerge each spring, with seed production continuing throughout the growing season. Even if the top growth is removed, the plant can regenerate from its root system, making consistent control essential.

Prevention & Control

Because of its deep root system, dandelion requires a selective broadleaf herbicide for effective control. Fall applications are most effective because the plant moves nutrients—and herbicides—down to its roots for winter storage. Hand-pulling can be effective in moist soil when the entire taproot is removed. Maintaining dense turf through proper fertilization and mowing helps prevent reinfestation.
