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.
Your DIY aerator needs to reach from 2 to 4 inches deep into the lawn, with the diameter of each plug about 1/2 to 3/4 inches wide. Spike aerators that simply make a narrow hole in the lawn are ineffective aerators. Most lawns benefit from yearly aeration, done when your lawn begins its season of active growth.
