Dandelions (Taraxacum officinale) are perennials with deep tap roots. They can be dug out but all of the tap root must be removed. Chemical control with 2,4-D or 2,4-D combinations are most effective in the spring and fall. Dandelions are more prevalent in a low-density turf. Increased lawn density and healthy turf will help reduce occurrence. Consider raising your mowing height and use less frequent, but deeper irrigation. To learn more about proper turf management techniques see fact sheet Lawn Care.
