Questions and Answers

What is the primary benefit of overseeding in conjunction with aeration?

  • It reduces the need for watering.
  • It prevents weeds from growing.
  • It helps seeds germinate more effectively. (correct)
  • It eliminates thatch build-up completely.

What does the aeration equipment do to the lawn?

  • It punctures the soil and removes small soil plugs. (correct)
  • It spreads fertilizer evenly across the lawn.
  • It kills off existing weeds and pests.
  • It adds a layer of mulch to the surface.

What role do the soil cores play after aeration?

  • They compact the lawn surface.
  • They create a barrier that prevents grass growth.
  • They dry out the soil and reduce moisture levels.
  • They provide a source of nutrients and microorganisms. (correct)

Core Aeration

A process that improves lawn health by creating small holes in the soil, allowing air, water, and nutrients to reach the roots.

Aeration Equipment

Special equipment used for core aeration, featuring hollow tines that puncture the soil and remove small plugs, called cores.

Cores (Aeration)

Small plugs of soil and thatch removed during aeration, containing beneficial microorganisms that help decompose thatch in the lawn.

Holes (Aeration)

The small holes left in the soil after core aeration, allowing air, water, and nutrients to penetrate the soil more easily.

Overseeding

A technique that involves spreading grass seed over the lawn, often in conjunction with core aeration, to encourage thicker and healthier lawn growth.

What is thatch?

A thin layer of organic debris (dead grass, leaves, and other plant material) that builds up on the lawn's surface.

Why is thick thatch bad for your lawn?

When the thatch layer becomes too thick, it prevents water and nutrients from reaching the grass roots, leading to lawn problems.

Study Notes

Core Aeration

  • Core aeration removes small soil cores and thatch (organic debris) from lawns
  • Recommended at least once a year, possibly twice for heavily compacted or thatch-filled lawns
  • Beneficial for lawns affected by drought, disease, or insect damage
  • Maintains long-term lawn health

Benefits of Aerating Lawns

  • Improves Drainage: Reduces risk of turf diseases and insect damage by improving water flow
  • Reduces Soil Compaction: Improves water, air, and nutrient flow to the roots
  • Reduces Thatch: Removes thatch (living and dead plant matter above soil level) which can restrict root growth and harbor pests
  • Enhances Deep Root System: Develops a strong root system, making the lawn more resilient to stress
  • Combines with Overseeding: Helps grass seed germinate and grow into a thicker, healthier lawn

How Core Aeration Works

  • Equipment: Hollow coring tines are used to pull small soil/thatch cores from the lawn
  • Cores: The cores are left on lawn to help break down thatch; these cores contain beneficial microorganisms
  • Holes: Holes in lawn allow air, water, and nutrients to reach the soil; holes will break down over a few weeks
