Heat waves can be brutal on lawns, turning vibrant green into brittle brown. However, with the right strategy, you can effectively maintain your lawn during a heat wave to help it survive and even thrive.
More Water During A Heat Wave
First and foremost, adjust your watering schedule. Deep, infrequent watering is key. Instead of daily sprinkles, aim for a half inch to one inch of water applied early in the morning (before 10 AM) to allow the water to penetrate deep into the soil before evaporation. This encourages stronger, deeper root growth, making your lawn more resilient to drought. Avoid watering in the evening, as prolonged moisture on the grass blades can encourage fungal diseases. You can however do a short cool-down watering session in the afternoon, after 4 PM but before 6 PM to help the lawn cool down from the heat.
Mow Less 🙁
Resist the urge to scalp your lawn or don’t bother mowing during a heatwave. Raise your mower blade to its highest setting, ideally 3-4 inches. Taller grass provides natural shade for the soil, reducing water evaporation and keeping the roots cooler. It also encourages a deeper root system. Furthermore, let the grass clippings lie; they return valuable nutrients and moisture to the soil.
Reduce foot traffic on your lawn as much as possible. Stressed grass blades are more susceptible to damage, and walking on them can break them, leading to brown spots. If you have areas of high traffic, consider temporarily rerouting pathways or laying down stepping stones.
Hold Off On Fertilizing During a Heat Wave
Finally, hold off on fertilizing. Applying fertilizer during a heat wave can stress your lawn further, as the grass is already working hard to survive. Wait until temperatures cool down before providing any additional nutrients.
By implementing these practices, you can significantly increase your lawn’s chances of emerging from a heat wave healthy and green. Patience and proactive care are your best tools in combating the summer heat.
