The Most Trusted Name in Lawn Care






Turfgrass in compacted soil (left) grows slowly, lacks vigor and becomes thin or does not grow at all. Core aeration (center) removes small cores of soil, depositing them on the surface of the turf. This improves the depth and extent of turfgrass rooting (right), and it can help save money on your water bill.


– What is Aeration?

Core aeration is a form of soil cultivation through the process of removing plugs of soil and thatch from the turf by passing a drum with hollow tines over the surface. Core aeration reduces soil compaction, promoting a greater exchange of air between the soil and the environment. The breakup of soil compaction creates small channels which allow water, oxygen, and nutrients to reach the turf roots.


What are the Benefits of Aeration?

Core aeration will not only make your turf healthier and more enjoyable, the process will save you money by reducing your maintenance needs. Professional lawn aeration results in the following benefits:

  • Increased oxygen deeper in the soil where grass roots reside.
  • Promoted soil water uptake and reduced water runoff and pooling.
  • Improved fertilizer uptake and less wasted product.
  • Reduced soil compaction allowing for stronger turfgrass roots and more turfgrass growth.
  • Less “baking” and “caked” soil, lowering heat and drought stress damage.
  • Enhanced turf resiliency and cushioning under each step.
  • Promoted thatch breakdown through organic microbial decomposition.


How Often is Aeration Recommended?

Lawn care professionals unanimously agree that seasonal lawn aeration provides the greatest benefit for your turf. Aeration in the spring will increase water absorption and encourage a thick lawn throughout the growing season. Fall aeration will help to break up the soil compaction which will naturally occur due to regular watering and the constant hardening from sunlight. Cool climate grasses like Kentucky Blue-grass and Rye-grass enjoy spring aeration to break up thatch that accumulates through the winter, while fall aeration enhances root growth which will promote a quick spring greening. Aerate regularly to maximize the efficiency of each core cultivation service.


How Do I Prepare for Turf Aeration?

Packed clay soils which are so common in Colorado will require a professional aeration to combat restrictive soil compaction. Heavily trafficked and south facing lawns are also heavily affected by soil compaction. The benefits of turf aeration are maximized by close tine spacing and deep plug depth. It is important to develop deep water penetration while being cautious not to turn the yard into a bog. Over-saturation of the lawn will not withstand the weight of the cultivation equipment, leading to likely turf damage.

Lawn Care Plus recommends heavy watering in the days leading up to the aeration service and restricted watering the day of service.


What Happens After the Aeration Service?

Following your core aeration, you will notice many small plugs of soil across your lawn. These plugs are intentionally left behind and will return necessary microbes when they disappear into the soil. The aerification cavities will now allow water and nutrients to penetrate much deeper into the soil.

Your lawn can now sustain longer periods without water. If you previously experienced pooling or poor drainage, you will see an immediate correction of this issue. Regular aeration will strengthen your lawn to withstand heat and drought stress. Within two weeks you will notice white roots spreading into the aerification cavities. This is a sure sign your lawn growth is promoted by core aeration.


Why Schedule with Lawn Care Plus?

Like many things in life, the quality of the product is determined by the type of service equipment. In core aeration, the standard of excellence is directly connected to the type of machine used. Some cut-rate providers will use an open-tine aerator which punches the soil, unlike the hollow-tine aerator used by Lawn Care Plus which pulls soil cores. Core depth is crucial to aeration efficiency, and Lawn Care Plus machines will reach core depths up to 2-3/4 inches and feature thirty tines spread over a 19-inch swath.
