What to know about hiring a Roswell pro

Southern lawns face armyworms in late summer (especially after wet stretches), brown patch fungus through humid June-September, and chinch bugs in St. Augustine. Most Southern states have nutrient management rules limiting phosphorus and timing summer nitrogen applications. Bermuda, Zoysia, and St. Augustine dominate because they thrive in heat and humidity while tolerating year-round insect pressure.

When evaluating O'Neill Landscape Group or any other lawn care provider in Roswell, ask how they handle the local timing windows above — a pro who can explain their pre-emergent schedule and seasonal approach is one who knows the GA climate.
