Heat stress is caused by hot summer temps and days upon days of dry, arid weather. Even a healthy, tough lawn can take a beating in those conditions.
And, bottom line, your lawn needs nutrients to survive. Before you reach for the fertilizer, though, think again; grass needs to take in a lot of energy to grow, and growing grass mid-summer could definitely stress your lawn out way more than it can handle.
If not tended to, your lawn might try and defend itself against drought and heat stress by going into what is called a “dormant state.” In this state and under heat duress, your lawn becomes more susceptible to damages caused by insects, weeds, and disease. All three are very active in the summer months. Reading this in the fall, winter or spring? You can help your lawn get ready for another summer by aerating it. Especially if it’s prone to a lot of foot traffic or heavy objects that can compact the soil, making it hard for air to reach the roots. This’ll only make the heat stress worse. Was this past summer a practically hot and arid one? We recommend reseeding your lawn with drought-resistant seeds after the drought has subsided in the fall. Check in with your local nursery for what seeds work best in your neck of the woods.
