What do landscapers spray on a lawn?

Landscapers typically spray a mix of selective herbicides and professional-grade fertilizers designed to target weeds while feeding your grass. They may apply pre-emergent products to stop crabgrass and other annual weeds from germinating, plus post-emergent sprays to knock out broadleaf weeds like dandelions and clover. In Oklahoma City, lawn pros also use liquid or granular fertilizers calibrated to local soil conditions to promote strong root growth and rich color. Depending on the property, they may include treatments for nutsedge, grassy weeds, or surface insects. Everything is applied at the correct rate and timing so the lawn thickens up, chokes out new weeds, and stays healthier through Oklahoma’s heat and weather swings.
