How To Know When To Aerate Your Lawn

Aerification or aeration accomplishes three key objectives:

  • Relieves soil compaction
  • Can improve the soil mixture around the root zone
  • Reduces the thatch accumulation

But do you know when to aerate your lawn?

Grass Type

Timing is vital for aeration. Your grass type will determine what time of year you should aerate your lawn. Lawn grasses fall into two categories: warm-season and cool-season. Warm-season grasses start active growth in summer. Cool-season grasses are dormant in the summer and begin growth in early fall.

Warm-season grass types – aerate in late spring / early summer: Bahia grass, Bermuda grass, Buffalo grass, Centipede grass, St. Augustine grass and Zoysia grass

Cool-season grass types – aerate in fall: Creeping bentgrass, Fescue (chewings, hard, red, tall), Kentucky bluegrass, Rough bluegrass, Ryegrass (annual, perennial)

Soil Type

Now that you know when to aerate, now determine how often you should aerate based on your soil type. Different soil types require more frequent aeration. Clay soil tends to be very compact and should be aerated at least once a year. You can aerate a sandy lawn once a year or alternate years. In dry climates, aerating twice a year will promote turf growth and health.
