How Does Pre-emergent Work



So what exactly is Pre-emergent and how does it work?

Pre-emergent herbicides are chemicals that prevent undesired weeds in your lawn. Contrary to popular belief, it does not prevent the germination of the seed, but actually kills the early roots so that the weed will not sprout. Due to the way these herbicides work, pre-emergent application timing is the most important aspect of successful weed prevention.

If the weed has already sprouted and is visible, pre-emergent herbicides will not solve the weed problem. Learn more about how to handle weeds that are already in your lawn.

When to Apply Pre-Emergent Herbicides?

Early Spring (even late Winter in some hot climates) and Fall are the most effective times to apply pre-emergent herbicides. They can be applied throughout the year, and will still prevent new weeds that sprout, however most weeds sprout during spring and fall, which is why timing your Pre-emergent application is so critical.

Spring applications target different weed species than Fall applications, so it is very important to know the type of weed you are trying to prevent for best results. Remove the guesswork by contacting us for a Free Quote and start enjoying your lawn today.
