Importance of Pre-emergent and Weed Control

Pre-emergent & Weed ControlRegardless of what the groundhog says, spring is right around the corner and it’s time to think about spring weed control.  With the winter, we’ve had, it’s time to apply pre-emergent for your yard. You have about a six-week window to apply pre-emergents, from the first of February to the middle of March.  There are three factors that will determine when a seed will germinate: soil temperature, moisture, and sunlight. The pre-emergent must be applied and active BEFORE that magic moment of germination occurs. Waiting too late to treat your lawn properly will still result in crab grasses and other weeds infiltrating their way into your grass despite the amount treatment you apply.

Pre-Emergent Herbicides work by creating a vapor barrier that controls weed growth prior to new weeds germinating. Spring applications need to be performed in late February into March as temperatures begin to reach 55 degrees F. Getting a pre-emergent down early will fight off new weeds that may be lurking in your soil and in some instances control young weeds that have not actively begun growing depending upon the product make up used.

This most important aspect of using a pre-emergent herbicide is effective timing for the control of weeds prior to them emerging from the soil. After lawn treatment is applied, make sure to leave the area alone for at least a week. This means no mowing, pickup football games, or any other activities that may disturb or aerate the soil.
