Aeration and overseeding are two essential lawn care practices that can significantly benefit your lawn. Aeration involves perforating the soil with small holes to allow air, water, and nutrients to penetrate deep into the root zone, which can help reduce soil compaction, improve drainage, break up thatch, and promote healthier grass growth. Overseeding, on the other hand, involves spreading grass seed over an existing lawn to fill in bare spots, improve density, and increase the overall health of the lawn. When combined, these two practices can work wonders for your lawn, making it thicker, healthier, and more resistant to pests, diseases, and drought.
