**Lawn Care Tip of the Month – Sierra Vista, AZ | May 2025** As temperatures in Sierra Vista begin to rise in May, it's essential to adjust your lawn care routine to keep your grass healthy through the approaching summer heat. Begin mowing your lawn more frequently, aiming to cut no more than one-third of the grass height at a time to avoid stress. Now is also the ideal time to apply a slow-release nitrogen fertilizer to encourage strong root growth and lush greenery. Be mindful of watering in the early morning to reduce evaporation and fungal risk—typically, 1 to 1.5 inches of water per week is sufficient. With these steps, your lawn can thrive through southern Arizona’s challenging climate.
