With a good understanding of what a lawn needs to grow and thrive, a lush, jewel-green yard can be the pride of any homeowner. Like all plants, grass needs a modicum of care to look its best. A homeowner can ensure that his lawn looks beautiful and stays healthy by having it professionally aerated as recommended.


For optimal growth, grass needs room to breathe and access essential nutrients through roots that grow down through the soil beneath each plant. Oxygen needed to metabolize the sugar stored during photosynthesis must be able to reach the plant's root area, or the grass will starve. However, the effects of time and ordinary use compact the soil underfoot that surrounds the lawn's root system. 

Densely packed dirt not only reduces the necessary flow of oxygen, but also makes it difficult for adequate water and nutrients to reach roots. In addition, roots unable to grow down through the tightly packed soil begin to grow laterally in their search for what they need. This creates a weak, shallow horizontal root system that depletes the soil and is preyed upon by opportunistic lawn pests such as grub worms.

What is core Aeration?

Aeration is a process that counteracts the effects of compacted soil and creates beautiful, healthy lawns. Although there are several ways to aerate a lawn, core aeration, which involves removing shallow plugs of grass and dirt at regular intervals, is most beneficial for several reasons. First, the holes the plugs leave behind allow oxygen, water and nutrients to reach the lawn's root system, loosen compacted soil and provide space for roots to grow as they should. Also, removing the plugs stimulates each grass plant to put out new shoots and grow new roots, naturally filling in the holes while increasing the lawn's density. Finally, core aeration helps to break apart and decimate thatch, which can also be detrimental to lawns.

When would be the time to aerate my lawn?

It is time to aerate the lawn if any of these conditions are present:

The lawn is thinning, fertilizing the lawn does not seem to improve it or water no longer soaks easily into the ground and excess runoff is present. All three of these are signs that the soil is heavily compacted and the lawn is being adversely affected.

The type of grass present determines the best time of the year to aerate the lawn. Cool season grasses benefit from fall aeration as long as there are four weeks of growing time for recovery before the first frost. Aerate warm weather grasses during the spring or summer when they are actively growing. In either case, lawn aeration is the key to restoring a tired, thin lawn to a lush carpet of green.
