Maintaining a green and healthy lawn exuding lushness that is the envy of your neighbours requires a little more than simply running a lawnmower over it once or twice a week during the summer months. To promote the finest growth the roots of your grass need to be able to breath freely and absorb moisture throughout the growing season; allowing this process to happen requires that you scarify or aerate your grass to remove built-up thatch and debris accumulated over the season’s grass mowing. This is a job best achieved using a powered aerator or scarifier, dispensing with the old fashioned and time-consuming methods of using a hand fork and sprung rake. It is possible to choose either petrol-powered aerators or electrically powered scarifiers and aerators, the choice depending on your personal preferences and the size of your garden. As a rule of thumb, if you need to treat an area of lawn more than half a tennis court in size, a petrol powered aerator will be best, giving you the freedom to work without the need for fiddly power cable extensions.
