Keeping Your Lawn Healthy This Summer in Coastal Georgia

Managing a healthy lawn in Brunswick, Georgia, is highly distinct from inland or North Georgia regions. Our coastal climate features high relative humidity and native sandy soils that drain water rapidly. To maintain a vibrant, green lawn during the peak growing months of June, July, and August, you must manage your specific turfgrass variety according to its unique requirements! According to data published by the University of Georgia (UGA) Glynn County Extension Office, our local area relies entirely on warm-season grasses. These grasses grow actively during the summer but require specific cutting ranges to prevent structural shock: Bermuda Grass (Common & Hybrid): Highly aggressive and sun-loving. Standard recommended height is 1 to 2 inches, but it requires a raised setting during heatwaves. Zoysia Grass: Dense and carpet-like, offering excellent drought tolerance. Standard recommended height is 1 to 2 inches. Centipede Grass: Known as “lazy man’s grass” due to low nitrogen needs. It thrives best in our naturally acidic sandy soils at a height of 1 to 2 inches. St. Augustine Grass: Highly tolerant of salt spray and partial shade near coastal waterways. Requires a taller cut of 2 to 3 inches to maintain its broad leaf health.

We’ve put together a full guide of answers to common questions that should help you keep proper tabs on your lawn this summer! The season is near, so dive in with us and beat the heat:

Q: How do I adjust my mowing height for the summer heat?

Raise your lawn mower deck by exactly 0.5 inches above your spring baseline during those aforementioned warmer months. Taller grass blades act as a natural umbrella, shading the soil surface beneath the canopy. This shading cools the root zone and dramatically reduces the rate of water evaporation from the soil. 

According to agricultural guidelines from Lawn Love’s Georgia Management Analysis, giving your grass that extra half-inch of canopy shield significantly lowers localized drought stress and prevents the soil from baking.

Q: Why should I strictly follow the 1/3 mowing rule?

Never slice off more than 1/3 of the total height of your grass blades during a single mowing session!

If heavy summer rains cause your lawn to shoot up rapidly while you are away, do not attempt to scalp it back down to its normal height all at once. Slicing off the majority of the leaf tissue removes the plant’s primary photosynthetic engine, shocking the root system and leaving the turf highly vulnerable to opportunistic weeds and heat death. Instead, bring the height down incrementally over multiple cutting sessions spaced three to four days apart.

Q: How often should I water my coastal lawn?

Irrigate your lawn deeply but infrequently, aiming for as close as you can get to 1 inch of total water per week (including natural rainfall).

Light, daily afternoon sprinkles do more harm than good; they saturate only the top millimeter of soil, forcing your grass roots to grow horizontally along the surface where they quickly bake in the sun. To build deep, drought-resilient root networks, split your irrigation schedule into two deep, 0.5-inch applications per week!

Q: What is the best time of day to irrigate?

Run your automated sprinkler systems exclusively in the early morning hours, between 4:00 AM and 10:00 AM.

Watering during the coolest part of the day ensures that wind drift and immediate solar evaporation do not steal your moisture before it reaches the root zones. Crucially, avoid watering your lawn late in the evening. Leaving grass leaves damp overnight in Brunswick’s high humidity creates room for destructive pathogens like brown patch and take-all root rot.

Q: How do I test and manage soil’s acidity?

Submit a localized soil sample to the Glynn County UGA Extension office to check your exact pH levels before applying amendments!

Brunswick’s native coastal plains are highly sandy and naturally tend toward acidic pH balances. While Centipede grass thrives perfectly in moderately acidic soils, varieties like Bermuda and Zoysia can experience nutrient lock-out if the soil becomes excessively acidic. If your official soil test indicates a pH below 6.0 for those specific varieties, a careful, measured application of agricultural lime will restore the needed chemical equilibrium.

Q: How often do my lawn mower blades need to be sharpened?

Sharpen and balance your lawn mower blades after every 25 to 50 hours of active mowing time.

Dull mower blades do not cleanly slice your grass; instead, they rip and shred the tops of the leaf tissues. These ragged, frayed tips quickly turn a straw-brown color.

Even worse, shredded tips leave jagged open wounds that serve as an unshielded entry point for airborne fungal spores and pests. A clean, razor-sharp cut allows the grass plant to seal the wound within hours.

Q: What are signs of destructive summer pests?

Regularly scout your lawn for localized patches of wilting or rapidly browning grass that do not respond to routine watering.

Brunswick’s high-humidity summers can bring severe pest pressures. Chinch bugs especially thrive in hot dry spells, puncturing leaves and injecting toxins that leave large, expanding circles of dead turf. Simultaneously, fall armyworms can migrate into lawns by the thousands, eating entire fields down to the dirt in less than 48 hours. Inspect your lawn closely at the soil line weekly; early localized spot treatments can save your entire landscape from destruction!

Q: Should I dispose of my grass clippings?

Leave your clean grass clippings on the lawn after every cut rather than bagging them for disposal.

As long as you are mowing frequently enough to meet the 1/3 rule, grass clippings decompose rapidly. They act as a free, organic mulching layer that insulates the soil surface against evaporation and breaks down into natural organic matter.
