Aeration and scarification are mandatory lawn care procedures. When aerating the lawn, you ensure normal air access to the root system, which contributes to the health of your lawn. After the aeration procedure, lawn feeding should be carried out, since aeration makes fertilization more efficient and targeted. Just like aeration, scarification improves the root system of the lawn. When combing scarifying a lawn covering, you remove the remnants of mowed and dead grass, the so-called "felt", which, like with aeration, improves air access to the root system.
