The Late-Summer Lawn Reset: Preparing Your Turf for Fall

August in Mississippi is famously brutal. While it might feel like the middle of summer to us, your lawn is already sensing the subtle shift in daylight. For Southern turfgrasses like Bermuda, Zoysia, and Centipede, August is a critical transition period. The choices you make right now will dictate how green your lawn stays into autumn, how well it survives the winter, and how vibrant it returns next spring.

To keep your yard the envy of the neighborhood, focus on these three vital late-summer care pillars.

1. Adjust Your Watering Rhythm

With temperatures routinely climbing, your first instinct might be to water your lawn daily. However, shallow, frequent watering actually harms your turf by promoting weak, surface-level root systems. Instead, shift to a “deep and infrequent” watering schedule. Aim for about 1 to 1.5 inches of water per week, delivered in one or two early-morning sessions. This forces the roots to grow deeper into the soil to find moisture, making your grass incredibly resilient against the late-summer heat.

2. Time Your Final Feedings

Your warm-season grasses are nearing the end of their peak growing cycle. If you plan to apply a summer fertilizer, August is your final window. Applying nitrogen-heavy fertilizers too late in the fall stimulates tender new growth that will easily be damaged by the first winter frost. Look for a fertilizer blend with a slightly higher potassium content this month to strengthen the grass’s root systems and boost its natural disease resistance before the colder months arrive.

3. Scout for Late-Summer Pests

August is prime time for turf pests in Tupelo, most notably armyworms and chinch bugs. Armyworms can devastate an entire lawn in a matter of days, chewing blades down to the soil line. Keep a close eye out for patchy brown areas or an unusual influx of birds feeding on your lawn. Catching these pests early with a targeted insecticide treatment will save your lawn from extensive damage that won’t have time to heal before winter.

By adjusting your care routine this month, you aren’t just maintaining your current summer green—you are investing in the long-term health of your landscape.

Total Lawn Care’s August Checklist

Make the most of your weekend yard work with these quick, expert-approved tips to keep your turf thriving into September:

• Raise the Blade: Raise your mower height by half an inch. Taller grass blades shade the soil, reducing water evaporation and protecting the root system from scorching sun.
• Mow It Dry: Always mow when the grass is completely dry to prevent clumping and minimize the spread of fungal lawn diseases.
• Prep for Pre-Emergents: Start planning your liquid pre-emergent herbicide applications for September. Timing this correctly prevents winter weeds like Poa Annua from taking over your yard.
• Sharpen Your Blades: Dull mower blades tear the grass rather than cutting it cleanly, leaving ragged brown tips that stress the plant. Sharpen your blades this month for a cleaner cut!
