Aeration is the process of increasing the porosity of your lawn, meaning adding pores. In the same way that your skin needs pores to breathe, your lawn also needs pores for many reasons. Without these pores, the soil becomes compacted, especially if the yard sees heavy use. Compacted soil cannot absorb the key nutrients it needs to stay healthy. Aeration opens the pores of our lawn to be able to absorb these key nutrients and allows your yard to flourish. Fall is the best time of year to perform lawn aeration in New England, right before the snow falls.
