Waking your lawn up the right way – Core Aeration

After you have dethached your lawn as needed, it is important to determine if your lawn is in need of core aeration. Core aeration is perforating the soil with holes to allow air, water and nutrients to penetrate the grass roots.  The main reason for aerating is to alleviate soil compaction.  The following are signs that your lawn is a candidate for aeration:

  • water puddling on lawn after rain or watering.
  • vehicles driving or parking on lawn.
  • lawn has been exposed to prolonged drought
  • difficulty sticking a screwdriver or a pencil into soil.
  • heavy clay soil.
  • thin, patchy or bare grass.

The following are results you can achieve through proper core aeration:

  • Enhanced soil water uptake.
  • Improved fertilizer uptake and use.
  • Reduced water runoff and puddling.
  • Stronger turfgrass roots.
  • Reduced soil compaction.


How to Core Aerate:

The first step in aeration is to determine which aerator is right for your job.  Lawn area and time allotted for job are the best determining factors. The following is a general guideline:

Residential walk behind =  12,000sqft and under

Commercial walk behind =  12,000-25,000 sq ft

Commercial ride on= 25,000sqft and over

It is important to note that all of the above machines produce the same end results in regards to core aeration.  The difference is sq ft coverage per hour and cost of rental unit

  • for best result aerate after a rainfall or watering your lawn
  • be  sure to flag irrigation heads as needed
  • for best results aerate lawn in two perpendicular directions
  • do not turn with tines engaged as this will create turf damage as well as increase the likelihood of damaging the aerator itself
  • after you aerate, leave soil plugs in place to decompose
  • additional watering is recommended after aeration
  • you can fertilize and seed your lawn immediately following aeration, However it is highly recommended to topdress* or amend soil prior to seeding for best results
