How to Help Your Lawn Beat the Summer Heat

The summer heat can not only be tough on you but your lawn. It is clear that your lawn is not prepared to handle summer stress without appropriate effort by you to keep it healthy and happy. As a homeowner, you need to be proactive and prepared to combat the diverse forces challenging your lawn throughout the summer. Not all of the action steps are exactly as you might expect.


Proper watering is essential. Without water, all organic material eventually dies. Keeping a maintained and regulated watering schedule will help your lawn get through the tough summer heat. Be sure to water early in the morning to avoid any unnecessary evaporation. Most lawns need about one inch of irrigation per week, either from natural rainfall or from an irrigation system. Depending on water pressure and the spacing of your sprinkler heads, irrigating  20-25 minutes is usually sufficient per area.

It may seem counterintuitive, but you absolutely can overwater your lawn, even when temperatures are approaching the 90’s and above. If the soil in your yard remains constantly wet, the grassroots are unable to take in a sufficient amount of oxygen, leaving them weakened to disease. The rule to remember is water deeply, less frequently, and only as needed.

Also, keep nighttime watering to a minimum as bugs of all sorts consider a damp environment a welcome mat.


Proper mowing height is equally crucial. Be sure to cut your lawn at the higher end of the recommended height for your grass. Taller grass allows for roots to grow deeper, resulting in a more drought hardy lawn. A good guide to adhere to:

  • cool season grasses prefer being cut at  3-5 inches
  • warm season grasses prefer to be kept at  2-3 inches

It is important that your mower blade is sharp. A dull blade that is tearing the grass will the leave the grass susceptible to disease.

Be sure to give your lawn the nutrients that it needs to combat the summer heat and stresses and nothing more. Cool season grasses ( fescues and bluegrasses) may not need summer fertilization while warm-season grasses (bermuda, zoysia, St Augustine, centipede) likely do. Having said that, any fertilizer that is nitrogen-rich is not what you or your lawn is looking for as temperatures soar. Why? The nitrogen will promote fresh growth which will not be strong enough to withstand the heat and stresses.  Overfeeding your grass means extra energy will be required for it to flourish, further stressing your lawn. That’s a task your lawn doesn’t need or want at this time.

Also, the wrong fertilizer plus excess sun exposure can easily equal scorched spots in your yard. Instead, consider applying Lawnifi™ Recover, a liquid fertilizer specifically designed to give lawns the boost they need to survive and flourish during the summer. Simple to apply, Lawnifi Recover contains a balanced NPK mixture, Carbon, Iron, Copper, and Zinc. Its patented Catalyst Absorption technology maximizes plant uptake and nutrient availability. That helps improve soil structure and enhances the growth of microbial populations needed to withstand summer stresses.

Healthier lawns are also best prepared to fight off unwanted pests as well as disease. Following these helpful tips should give your lawn the best chance to not merely survive but thrive during the challenging summer months.
