**Lawn Care Tip of the Month – July 2025 | St. Louis, MO** July in St. Louis brings intense heat and humidity, so it's crucial to adjust your lawn care routine to keep your grass healthy. Mow high—keeping your grass around 3 to 4 inches tall helps shade the soil, preserve moisture, and reduce weed growth. Water deeply but infrequently, aiming for about 1 to 1.5 inches of water per week early in the morning to reduce evaporation and prevent fungal disease. Hold off on fertilizing cool-season grasses like fescue or bluegrass until fall, as summer stress can make them vulnerable to burn. Regularly inspect for pests like grubs, which tend to become active this month in the St. Louis area. A healthy summer routine now will prepare your lawn for strong fall growth.
