  • Work gloves

Step-by-Step Instructions

1

Prepare Your Lawn

Mow your lawn to about 2-3 inches tall, slightly shorter than usual. Water the lawn thoroughly 1-2 days before aeration to soften the soil.

Pro Tips

  • Avoid aerating during drought conditions
  • Mark sprinkler heads and utility lines
2

Choose the Right Equipment

Select between manual, gas-powered, or electric aerators. Core aerators that remove soil plugs are more effective than spike aerators.

Pro Tips

  • Rent equipment if you don't own an aerator
  • Manual aerators work well for small lawns
3

Aerate in a Pattern

Start at one corner and work in straight lines, overlapping slightly. Make multiple passes in different directions for thorough coverage.

Pro Tips

  • Aerate when soil is moist but not wet
  • Focus on high-traffic areas
4

Leave the Plugs

Don't remove the soil plugs - they'll break down naturally and return nutrients to the soil. They'll disappear within 2-4 weeks.

Pro Tips

  • Plugs contain beneficial microorganisms
  • They help improve soil structure
5

Post-Aeration Care

Water the lawn lightly and consider overseeding or fertilizing. Avoid heavy traffic for 2-3 weeks to allow recovery.

Pro Tips

  • Best time to overseed is immediately after aeration
  • Apply fertilizer within 48 hours

Frequently Asked Questions

How often should I aerate my lawn?

Most lawns benefit from annual aeration. High-traffic areas or compacted soil may need aeration twice per year.

What's the best time to aerate?

Early fall (September-October) is ideal for cool-season grasses. Spring (March-May) works for warm-season grasses.

Should I aerate a new lawn?

Wait at least one year after establishing a new lawn before aerating to allow the root system to develop.

Can I aerate when the lawn is wet?

No, avoid aerating when the soil is too wet as it can cause compaction and damage the lawn.
