Lawn aeration and dethatching are meant to solve the same problem, loosening up compacted soil so that the root systems can grow and receive more water, oxygen, and nutrients. Aeration is the gentler option and often the preferable one. Dethatching completely tears out the thatch layer of the lawn and can inadvertently yank out healthy grass if done incorrectly. Aeration loosens the soil and only removes small cores of it.

The frequency of lawn aeration depends on various factors such as soil type, grass variety, and lawn usage. In most cases, aerating once a year, typically in the fall or early spring, is sufficient to maintain a healthy lawn. However, lawns subject to heavy foot traffic or especially compacted soil may benefit from more frequent aeration, possibly every six months. It's essential to assess your lawn's specific needs and consult with a lawn care professional if you're unsure about the ideal aeration schedule for your property.

The frequency of lawn aeration depends on factors such as soil type, grass variety, and lawn usage. In general, it is recommended to aerate cool-season grasses like Kentucky bluegrass or fescue once a year during the fall. On the other hand, warm-season grasses such as Bermuda or zoysia benefit from aeration in late spring or early summer. However, it's essential to assess your lawn's specific needs, as signs of compaction and reduced grass health may indicate the need for aeration outside these general guidelines.
