Weed Control

A properly maintained lawn is the first line of defense against weeds. Weeds often indicate problems in the lawn environment. Therefore, weeds can often be controlled by altering the environment to favor the grass instead of the weeds. The environment can be manipulated by adjusting the mowing height or frequency, altering the amount of time between irrigation or fertilizer application, or aerifying the soil.

In addition to proper fertilization techniques, preemergents are another effective solution for nurturing a healthy lawn, and should also be applied before spring, typically at the beginning of the calendar year. A preemergent is a type of herbicide that forms a chemical barrier on the surface of the soil, which prevents weeds from emerging. Some weeds are difficult to control once they have sprouted in the lawn, making a preemergent a must for comprehensive lawn care.

For lawns that already have minor or severe weed problems, postemergence herbicides are available to kill weeds after they are actively growing. These herbicides are most effective when weeds are young and growing rapidly. The herbicide must be absorbed through the leaves, making liquid sprays the most efficient intervention.
