How does aeration benefit your lawn?
Just like any plant, grass needs water, air and nutrients to grow well. Unlike your other plants, grass is often played on, walked on, driven on by equipment, and more. All of this action your lawn receives means that the soil holding the roots of your grass gets compacted. Dense, compacted soil blocks your grass from getting the proper amount of water, air, and nutrients it needs to thrive.
When aeration is performed, it breaks holes in this compacted soil, alleviating the compaction and allowing the good stuff to get the roots of your grass. This is why even after proper watering and fertilization, sometimes lawns still struggle.
Not all lawns need aeration every year. The sandy soils of our area tend to allow for better drainage than more clay filled soils. Usually, your grass will signal when it is time for aeration. You may see puddling of water on your grass, decreased green color, or thinning grass. To test if you soil is compacted, you can simply grab a screwdriver and press it into your turf. If you meet much resistance, your lawn needs aeration.
