Steps

1
Determine the best timing based on grass type. Aerate cool-season grasses (e.g., bluegrass, fescue) in early spring or early fall. Aerate warm-season grasses (e.g., Bermuda, St. Augustine) in late spring or early summer.
Tip: Avoid aerating during drought or extreme heat to prevent further drying out the grass.
2
Prepare the lawn by mowing the grass shorter than usual a few days before aerating. This allows the aerator tines to reach the soil more easily.
Tip: If using a spike aerator, rake and remove all leaves and debris first.
3
Soften the soil by watering the lawn well (applying about one inch of irrigation) the day before you plan to aerate, or time the task for one day after a heavy rain.
Tip: Aerate in the morning to prevent moisture from evaporating.
4
Identify and mark all hidden obstacles, including sprinkler heads, shallow utility lines, and stumps using landscaping flags or spray paint.
5
Execute the aeration. For core aeration, push or pull the machine in a criss-cross pattern across the lawn. For spike aeration, work in straight lines, turning and traveling in the opposite direction for each pass.
Tip: Ensure holes are approximately 2 to 3 inches deep and spaced about 3 inches apart.

6
Verify coverage. If the soil shows heavy compaction, go over the lawn a second time in a perpendicular direction to the first pass.

7
Perform post-aeration care. Leave core plugs on the surface to break down naturally. Water the lawn immediately after finishing and avoid walking on the grass for a few days.
8
Apply optional enhancements. While the holes are open, fertilize, add soil amendments, or overseed to increase seed-to-soil contact and nutrient penetration.
Tip: Water newly aerated and seeded lawns every few days for about 2 weeks to aid regrowth.

Pro Tips

  • Core aeration is best for large yards, clay soil, or thick thatch, while spike aeration is better for sandy or lightly compacted small lawns.
  • Aerate every 1 to 5 years depending on soil type: clay/high-traffic lawns need it 1-2 times per year, while sandy/low-traffic lawns only every 2-3 years.
  • Liquid aerators are generally less effective than physical mechanical aeration for severe compaction.
