Keep your lawn moist by watering early in the morning or late evening. This helps reduce water loss from heat and wind. Avoid watering during the hottest part of the day. Use a sprinkler for about 20-30 minutes to soak the soil deeply. Light, frequent watering only wets the surface and weakens roots.
Feed your lawn with a slow-release fertilizer. This gives grass steady nutrients over time. Apply fertilizer every 6-8 weeks during summer. Remove weeds promptly to stop them from stealing water and nutrients. Use a weed control product that is safe for your grass type.

Cutting grass too shortharms the lawn. It stresses the grass and makes it weak. Short grass dries out faster and lets weeds grow. Leaving grass a bit taller keeps it cooler and helps it hold water. A good mowing height in summer is around 3 inches.
