Questions and Answers

Overseeding is a process that involves spreading grass seed over the lawn.

Core Aeration

A lawn care technique that involves using equipment with hollow tines to puncture the soil, removing small soil plugs called cores.

Cores

Small soil plugs removed from the lawn during core aeration, containing beneficial microorganisms.

Thatch

A layer of dead grass and organic matter that can prevent water and nutrients from reaching the soil.

Holes

Holes left in the soil after removing cores during core aeration, allowing air, nutrients, and water to reach the soil.

Frequency of Aeration

Typically, aerating your lawn once a year is sufficient. However, heavily compacted or thatchy lawns may require aeration twice a year (spring and fall).

Study Notes

Core Aeration

  • Core aeration removes small soil cores and organic debris (thatch) from lawns
  • Generally recommended at least once a year, but may need twice yearly for thick thatch or compacted soil
  • Lawns affected by drought, disease, or insects also benefit from aeration
  • Helps maintain long-term lawn health

Benefits of Aeration

  • Improves Drainage: Reduces turf diseases and insect issues by improving water drainage
  • Reduces Soil Compaction: Allows water, air, and nutrients to reach the root system
  • Reduces Thatch: Removes the layer of living and dead plant material above the soil, reducing root issues.
  • Enhances Deep Root System: Promotes deeper root development for stronger, healthier lawns
  • Combines with Overseeding: Holes created allow grass seeds to fall in and germinate, leading to thicker lawns
