In order to take advantage of an evergreen and lush meadow, it is necessary to ventilate the ground cyclically. This process allows you to remove some debris in the soil, such as plant deposits or moss, which could take away oxygen and nutrients from the grass, preventing its proper growth. To achieve this goal, specific tools are used, called aerators: how do they work and, above all, which is the choice between electric or manual?
In general, the scarifier is a tool with toothed rollers: penetrating deep into the ground, it allows both to carry oxygen and to remove residues that could limit the growth of the tufts of grass. There are different varieties of tools available on the market: there are manual models, which work by pushing, or electric models. The latter have similar features to the common lawnmowers, although the operation is very different, and are suitable for both the speed of execution and to cover large fields. Even though they are less in demand, there are petrol or shoe aerators: in this case they are special toothed soles to be applied directly to your work shoes. The lawn is usually aired at the end of winter, just before the start of the grass’s life cycle. Here are a few tips.
