Lawn Aeration

We often get asked three questions with regards to aerating: 1) Why is aerating good for my lawn, 2) How often do I need to aerate, 3) When do I need to aerate?

1) Aerating serves multiple purposes for a healthier turf. The number one reason to aerate is to reduce soil compaction. Over time, the soil gets compacted from lawn mowing equipment, foot traffic, etc. Core aeration removes “plugs” of soil and brings them to the top of the surface. In addition to reducing soil compaction, aeration allows water and nutrients to penetrate deep into the soil. As these plugs are pulled, there is essentially a small hole left where the water and nutrients don’t have to fight through turf, thatch and compacted soil. Lastly, aeration also reduces thatch! If done properly (making two passes) core aeration will remove 10% of thatch buildup.

2) Aeration can be done multiple times per year, but twice is our recommendation.

3) We recommend aerating once in the spring, and once in the fall. There are two times during the year when it is unwise to aerate: The first is when the soil is frozen, and the second is when the weather is especially hot and dry. It is an excellent practice to fertilize immediately following an aeration to allow the fertilizer to penetrate deep into the soil.
