When aerating your lawn, it is best to aerate on a day where the temperatures are milder and the soil in a moist condition, which will make the aerating process much easier. Aerating wet soil can be a real nuisance due to the fact that the plugs will get stuck in the hollow tines and can further compact you soil.
Both Cellura and Keyes say the best time to aerate a lawn is in the fall or spring, when there is plenty of moisture in the soil. Cellura adds that new lawns can benefit from aeration twice a year â once in the fall and again in the spring. âIt reduces your thatch, which is a layer between the soil and the grass of dead roots,â Cellura says. âWhen someone has a newer lawn, they usually have thatch [buildup] from the sod.
