Aeration and Seeding: Why It’s Necessary

Aeration and Seeding should be done in the Fall not only to relieve soil compaction, but also to repair Summer insect and drought damage. In addition, it will also ensure that your lawn continues to thicken and develop a strong root system for next year.

The main reason for aerating is to alleviate soil compaction. Compacted soils have too many solid particles in a certain volume or space, preventing proper circulation of air, water and nutrients in soil. Excess lawn thatch or heavy organic debris buried under the grass surface can also starve the roots from these essential elements.

This process extracts “plugs” of existing soil and deposits them on the surface of the lawn.

  • Relieves soil compaction allowing grass roots to expand
  • Allows air, sunlight, rain/water, fertilizer and nutrients to penetrate deep into the root system where it is needed
  • It brings microorganism’s to the surface. While they are working their way back into the soil, they help to break up the thatch layer that can accumulate on the surface of the soil.
  • The cores (plugs) break up over a week or so, providing a light “topdressing” of fresh soil, which also aids in the decomposition of any accumulating thatch.
  • The aerator holes create a moist , protected, environment for seedling growth.
    It permits the root system go deeper where the ground temperature is cooler and moister, allowing the grass to stay greener longer in the heat of the summer.


The best time to do seeding is in the Fall! We recommend that seeding be done following an aeration or verticuttingFor the best results . This will allow you to create a seed bed by loosening the soil with the aeration or verticutting. This allows you the most “seed to soil” contact, which is crucial to seed germination. The nature life cycle of most grasses, which go to seed during summer and then germinate in the early Fall. By seeding in the fall  it prevents newly seeded grass from getting burnt in the hot Summer months. Thereby allowing you to get the best, most vigorous stands with the least competition from weeds and insect pests.
