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.
Prepare the Lawn for Aeration. Water the lawn thoroughly one to two days prior to aerating your lawn. Apply at least 1 of water to the grass; this can be measured by placing an empty tuna can in the middle of the watering zone. If the can is full, then 1 of water has been applied to the grass. Watering the lawn will help the aerator penetrate the soil and pull out soil cores much more easily. Flag irrigation heads and other hidden objects in the lawn so that you will avoid them when operating the aerator over this area.
