Many grass species enter a state of dormancy during periods of extreme heat.
One of the primary reasons for allowing your lawn to go dormant during the summer is to conserve water. Lawns, especially those made up of cool-season grasses like Kentucky Bluegrass, require significant amounts of water to maintain their lush, green appearance in hot weather. By letting your lawn turn brown, you reduce water usage, which is crucial in times of water scarcity and helps protect valuable water resources for other essential uses.
Letting your lawn go dormant during the hottest months can actually be beneficial for the grass itself.
Many grass species naturally enter a state of dormancy during periods of extreme heat and low moisture as a survival mechanism. In this dormant state, the grass stops growing and conserves its energy, allowing it to withstand the stress of high temperatures and reduced water availability.
When cooler, wetter weather returns in the fall, the grass will typically green up and resume active growth. This natural cycle helps maintain the health of the grass without the need for excessive watering or chemical interventions, promoting a more sustainable and environmentally friendly approach to lawn care.
