INTRODUCTION
What is aeration?
For your lawn to grow at its best, the roots need to be surrounded by air pockets in the soil so that oxygen,
water and nutrients can be absorbed. Air pockets in the lawn shrink as the earth is compacted by pedestrian
traffic, rainfall, irrigation, or construction and landscaping work. Mechanically removing small plugs (cores) of
soil and thatch increases the quantity of air in the soil considerably. In this manner, the aeration process
promotes new root growth and improves the lawn’s ability to absorb water and nutrients. The end result is a
healthier, more beautiful lawn.
When should I use the removable weights?
The soil conditions dictate whether extra machine weight will be required for effective aeration. The weights are
provided to give you added control and greater tine penetration.
Should I water the lawn before aeration?
Normally, it is not necessary to water the lawn before aerating. In extreme conditions, such as highly
compacted clay soil, a simple test can be used to determine whether you need to water before aerating. Use a
garden spade, weeding tool or a large screwdriver to test the ground’s hardness. You should be able to push the
tool 5 - 7.5 cm into the ground with little effort. If you are unable to do so, watering is advisable. Watering the
day before should give sufficient time for the soil to absorb the moisture. Use your hand tool to gauge the
effectiveness of your watering.
