The use of herbicides, also known as weed killers, is vital to good lawn care when it comes to protecting your grass. Pre-emergent herbicides kill weeds before they sprout, and timing is critical for obtaining the best results.

Applying a pre-emergent treatment too late or too early will waste both your time and money. So when should you spray pre-emergent herbicides?

How They Work

Pre-emergent herbicides are a preventative measure for controlling weeds. Proper use creates a chemical barrier that will not kill established plants. The barrier only affects seeds, such as those belonging to weeds, and will break down in six to eight weeks.

Therefore, using a pre-emergent treatment requires proper timing to be effective. Apply them very early in the spring season, and once again in the fall season before your grass goes dormant for the winter.

Proper Lawn Care To Fight Weeds

Proper fertilization, mowing, irrigation, and soil aerating are all important factors in creating a dense lawn. However, weather-related events are beyond our control.

Unexpected drought or excessive precipitation can cause the lawn to thin out or become overwatered. Applying a pre-emergent herbicide can serve as an insurance policy in the off-chance that your yard loses its luster due to fickle weather.
