**Lawn Care Tip of the Month – July 2025 | Boulder, CO** July in Boulder brings high temperatures and occasional afternoon thunderstorms, making consistent lawn care essential to keep your grass healthy and vibrant. To combat heat stress, mow your lawn at a higher setting—around 3 to 3.5 inches—to provide shade for the soil and retain moisture. Water deeply but infrequently, ideally in the early morning, to encourage deep root growth and reduce the risk of fungal diseases. Don’t forget to sharpen mower blades for a clean cut and consider applying a slow-release nitrogen fertilizer mid-month to support sustained summer growth. Keep an eye out for common Colorado pests like billbugs and grubs, which can damage roots if left unchecked.
