The answer to 'aeration vs' is that aeration and overseeding are two distinct lawn care practices that serve different purposes. Aeration involves punching small holes in the soil to allow air, water, and nutrients to reach the grassroots, while overseeding involves spreading new grass seed over an existing lawn to fill in bare spots and thicken the turf.
Aeration is beneficial for compacted soil, as it helps to break up the soil and improve drainage and oxygen flow to the roots. This can lead to a healthier, more vigorous lawn. Overseeding, on the other hand, is used to introduce new grass varieties or fill in bare patches, which can help to improve the overall appearance and density of the lawn.
