Aerating helps your lawn gain access to increased oxygen as well as other nutrients. When an aerated lawn is watered, it is easier for the water to reach the roots. All these help the roots to thrive and ensure better health of the lawn as the grass grows thick and softens the soil.
A lawn that has been aerated will require only half the amount of water than one which has not been aerated. Spike aeration is useful in clearing dense thatch facilitating for the proper movement of air and water. Aeration will break up your hard soil and allow a healthier lawn.
