Yes! Aeration is extremely important for a healthy lawn. It is even more important if your lawn is getting compact due to being in a high traffic area. The process of aeration removes small plugs from your lawn, creating holes that allow water, air, and fertilizer down to the root level.This produces stronger roots, reduces disease and thatch build-up, and prevents water runoff. Plugs should be left on the lawn to break down and return into the soil.
