Dandelions have very small yellowish florets collected together at the flower head and produced on stalks. Dandelion flowers grow unbranched on one single stem, and are often leafless and hairless. The flower head of a dandelion weed is open during the daytime, but will close at night.
Dandelions mature into white spherical fuzzy heads with fine hairs of seed. Mature dandelions are often called “blowballs” for their ability to greatly disperse over long distances when aided by the wind.
Is a dandelion a weed?
Dandelions add minerals and nitrogen to the soil. However, they are often considered as unwanted in residential and recreational lawns, and may rapidly colonize in unhealthy lawns. Additionally, dandelion pollen may cause allergic reactions among sensitive individuals.
Dandelions are easily controlled with a 3 way broad leaf weed control. A 3 way weed control contains 2,4-D, Dicamba, and MCPP. Our professional weed control applications can easily control this weed.
The best time to spray for dandelions is in the fall. They are in the yard and actively growing in the fall, but they are not seen because they are smaller, under the canopy of the grass, and they are not flowering. In the spring they cannot be killed until they are flowering. Once they are sprayed, they will twist and curl within a day. Since they have a very long tap root, they will continue to flower as they die, which may take 2 – 3 weeks before they disappear.
