As we move into the dog days of summer here in Newton County, landscapes across our community begin to show signs of stress. Brown patches in lawns, wilting garden plants, and an increase in certain pests are all too common in late July. As an Extension Agent, I often hear from homeowners who are unsure how to care for their lawns and landscapes during this hot, dry stretch. Here are a few timely tips and research-based practices to help your yard thrive as we transition into August.
1. Water Wisely – and Legally
By late July, rainfall often becomes inconsistent. Most established lawns and plants need about 1 inch of water per week. Water deeply and infrequently to encourage strong root systems—this means watering only once or twice a week, but for longer durations.
Consider landscape and turf irrigation between 5 a.m. and 10 a.m., which helps reduce evaporation loss and prevent disease. Avoid watering during the heat of the day or when wind speeds are high.
2. Be Mindful of Mowing
Raise your mower blade! Cutting grass too short in summer can stress your lawn and make it more susceptible to drought and heat. Tall fescue should be kept at about 3 inches, while Bermuda and Zoysia grasses do well between 1–2 inches depending on variety. Sharpen mower blades regularly to avoid tearing grass, which invites disease.
3. Watch for Heat-Loving Pests
Chinch bugs, armyworms, and spittlebugs become more active in late summer. If you notice thinning areas in your lawn or unusual insect activity, it may be time to investigate. Avoid unnecessary pesticide use—accurate identification is key. Bring a sample to the Extension office or call us for assistance.
4. Avoid Fertilizing Cool-Season Grasses
Now is not the time to fertilize cool-season grasses like tall fescue. Fertilizing in summer can stress the plant and promote disease. Hold off until early fall (around mid-September) for your next round of fertilizer. Warm-season grasses, on the other hand, can receive their final fertilization of the season in late July or early August.
5. Plan Ahead for Fall Planting
Late summer is a great time to start planning for fall garden and landscape projects. Soil testing is recommended before adding any fertilizers or lime. Our Newton County Extension office provides soil test kits and guidance for interpreting results.
