WHERE DO BROADLEAF WEEDS COME FROM?
The seeds of broadleaf weeds occur naturally in all soils and can persist for over 30 years. Most broadleaf weeds are excellent seed producers. Many can produce thousands of seeds that are dispersed into your lawns from miles away. Inexpensive grass seeds bought at stores can also have unwanted weed seeds. New topsoil that is brought in can also have broadleaf weeds in it.
TIPS TO MINIMIZE BROADLEAF WEEDS:
Dandelions and other broadleaf weeds are among the most troublesome pests in lawns today. The best way to minimize weeds in your yard is through good cultural practices. Incorrect cultural practices encourage weeds through poor management techniques. Mowing too short and non-fertility programs, as well as over or under-watering can spread weed growth. Weeds also infest in areas killed by disease and insects.
HERBICIDE CONTROL MEASURES:
Multiple active ingredients will control a wider spectrum of broadleaf weeds rather than a single active ingredient. It is crucial to read, understand and follow all directions on the herbicide label. The best time to apply a general-purpose broadleaf herbicide is mid-September to early November. Fall is the best time to control perennial broadleaf weeds such as dandelion, plantain, and clover. The second most ideal time to apply general-purpose broadleaf is in late spring or early summer after the weeds have flowered. Be careful not to spray ornamentals, trees, flowers, and vegetable gardens because they will be damaged by the herbicide.
