In the Southwest, maintaining a vibrant and healthy lawn during the intense heat of August can be challenging. However, with the right summer lawn care practices, you can ensure your lawn remains lush and green. This post delves into essential Southwest lawn maintenance strategies, focusing on watering schedules, mowing advice, and fertilization tips tailored for the scorching summer months.

Watering Schedule

One of the most critical aspects of summer lawn care in the Southwest is an efficient watering schedule. The high temperatures and low humidity characteristic of this region necessitate a strategic approach to irrigation. Here are some key pointers:

  • Early Morning Watering: Water your lawn early in the morning, preferably between 4 AM and 8 AM. This timing reduces evaporation loss and ensures the grass absorbs maximum moisture.
  • Deep and Infrequent Watering: Instead of frequent shallow watering, aim for deep irrigation once or twice a week. This encourages roots to grow deeper, making your lawn more drought-resistant.
  • Use Drip Irrigation or Soaker Hoses: These systems deliver water directly to the roots, minimizing waste and ensuring efficient hydration.

Mowing Advice

Mowing is another crucial component of Southwest lawn maintenance. Proper mowing techniques can significantly affect your lawn’s health during the hot summer months.

  • Mow High: Set your mower blades higher to leave your grass longer, around 3 to 4 inches. Taller grass provides shade for the soil, reducing evaporation and helping retain moisture.
  • Keep Blades Sharp: Sharp mower blades make clean cuts, reducing stress on the grass and preventing disease.
  • Mow Frequently: Regular mowing ensures that no more than one-third of the grass blade is cut at a time, promoting healthier growth.

Lawn Fertilization

Fertilization in August requires a careful balance to avoid overstressing your lawn. Here are some fertilization tips tailored for the Southwest:

  • Use Slow-Release Fertilizers: Opt for slow-release fertilizers that provide nutrients gradually over time. This approach helps sustain grass growth without causing a sudden spike in nutrient levels that could stress your lawn.
  • Apply Iron Supplements: Lawns in the Southwest often suffer from iron deficiencies due to alkaline soil conditions. Applying iron supplements can help maintain a deep green color without excessive growth.
  • Avoid High Nitrogen Fertilizers: High nitrogen fertilizers can promote rapid growth that isn’t sustainable in extreme heat. Instead, choose balanced fertilizers that support steady growth.

Additional Tips

In addition to watering, mowing, and fertilization, consider these supplementary tips to enhance your summer lawn care routine:

  • Aeration: If your lawn feels compacted or has heavy foot traffic areas, aeration can improve water penetration and root development.
  • Mulching: Leave grass clippings on the lawn after mowing to act as a natural mulch that helps retain moisture and provides organic nutrients as it decomposes.
  • Weed Control: Stay vigilant about weeds that compete with your grass for water and nutrients. Spot-treat weeds with appropriate herbicides or remove them manually.

By following these comprehensive August lawn tips, you can keep your Southwest lawn thriving even in the hottest part of summer. Remember that consistent care and attention to detail are key to maintaining a resilient and beautiful lawn throughout the season.


By implementing these practices into your summer lawn care regimen, you’ll be well-equipped to handle the unique challenges posed by the Southwest’s climate. Your commitment to optimal watering schedules, proper mowing techniques, and balanced fertilization will result in a robust and picturesque lawn that stands up to August’s heat with vigor.
