A barrier in the soil

Pre-emergent creates a protective barrier in the soil so weed seeds cannot sprout. It works on common weeds like crabgrass, dandelions and other broadleaf weeds, with less work for you than constant weeding.

Our materials are federally labeled as safe around hundreds, and in some cases thousands, of tested plants. Pre-emergent goes down in every area where you want weed control, including rock and shrub beds, and our technicians then carefully apply post-emergent to any growing weeds that break through.

What Colonial guarantees

Because of environmental and local factors, we cannot guarantee the materials themselves. What we guarantee is service. If you are a full pre-emergent program client, we will warranty our work for any breakthrough that happens between scheduled applications.

If you see weeds come through, reach out so we can schedule a technician.

Richland pre-emergent questions

  • When should it be applied?

    Early spring and fall suit most lawns, and we help you pick the timing for yours.

  • How often do I need it?

    Most lawns benefit from twice a year, and your plan depends on your weeds and your lawn.

  • Can I apply it myself?

    You can buy and apply it. Professional application gives more even coverage and the right timing, which lets a lawn stay weed-free longer.

  • Is it safe for pets and children?

    Products are safe when applied correctly, and our technicians follow every safety guideline.
