These high traffic areas can usually be done by “hand” as described in the next section. The type of grass will determine whether to aerify in the fall or in the summer. Lawns composed of cool-season grasses such as Kentucky bluegrass and tall fescue are best aerified in the fall when there are less scott accugreen 3000 heat stress and danger of invasion by weedy annuals.

You need to produce a number of holes, at least 4 inches apart, to improve the appearance and density of the stand.

Turfgrass in high traffic areas may need aerification more often than the rest of the lawn.
