The best time to dethatch your lawn is early in the morning — typically before 10 or 11 a.m. — when the grass is least stressed and can benefit from optimal growing conditions.
The cooler morning temperature not only alleviates the stress of the plant but also helps it deal with the strain of dethatching, leading to a healthy, flourishing lawn.
It’s advised to limit foot traffic on the lawn a day prior to dethatching, as this allows the grass to recover overnight, reaffirming morning as the ideal time for this process.
