As the summer heat rolls in, so do some of the most aggressive and unsightly grassy weeds. Crabgrass, goosegrass, dallisgrass, and other summer annuals thrive in warm weather and can quickly take over even the healthiest lawns. At Green Care Turf Management, we’re keeping a close eye on these unwanted invaders—and we’re ready to fight back with strategic post-emergent weed control.

What Is Post-Emergent Control?

Unlike pre-emergent treatments, which prevent weed seeds from germinating in the spring, post-emergents are designed to kill weeds that have already broken through the surface. If you’re seeing patches of unfamiliar grass creeping into your lawn mid-season, a post-emergent application is likely the solution.

Why Summer Grassy Weeds Are So Tough

Summer annual grasses grow fast, tolerate heat, and can be difficult to distinguish from desirable turf. They often take hold in areas that are already stressed—like thin spots or along sidewalks and driveways. Left unchecked, they compete with your lawn for water and nutrients and can leave lasting damage that shows up even into the fall.

Our Approach to Summer Weed Control

At Green Care, we tailor our post-emergent treatments to the specific weeds and grass types present in your lawn. Our licensed technicians use selective herbicides that target the invasive grasses without harming your desirable turf. We also monitor timing closely—many products work best when applied while the weeds are still young and actively growing.

What You Can Do

  • Keep your lawn mowed at the proper height. Taller grass shades out weed seeds.
  • Water deeply but infrequently. This encourages deep root growth in your turf and discourages shallow-rooted weeds.
  • Avoid disturbing the soil unnecessarily, which can bring buried weed seeds to the surface.

Thinking Ahead

While post-emergents are crucial during the summer months, they’re just one part of a complete lawn care program. Consistent treatments, proper fertilization, and soil health all contribute to long-term weed suppression. As summer winds down, we’ll be preparing lawns for fall renovation, aeration, and overseeding—so it’s important to keep the weeds under control now.
