**Lawn Care Tip of the Month – May 2025 | Flagstaff, AZ** As temperatures steadily warm up in Flagstaff this May, now is the ideal time to begin your summer lawn care routine. Cool-season grasses like Kentucky bluegrass and fescue thrive in the region’s unique climate, so be sure to mow regularly, keeping grass height around 3–3.5 inches to promote deep root growth and shade out weeds. Also, begin a consistent watering schedule—early mornings are best to reduce evaporation. Don’t forget to fertilize with a balanced, slow-release formula to feed your lawn throughout the growing season. A healthy, well-fed lawn now will stand up stronger against summer heat and monsoon rains.
