The scarifier is a firm favourite and is also a good cartridge for those who are 'beginners' when it comes to lawn cultivation. It is designed to remove surface debris, thatch and dead moss from your lawn prior to mowing. We recommend using this cartridge about once a month during mowing season to keep on top of your lawn. It does also help to lift lateral growth upright prior to cutting.
The verticut cartridge can be used roughly every two weeks.
The aims of verticutting:
To prune the grasses to improve tillering and stolon formation. This increases turf density.
To control thatch. The verticut cartridge blades are designed to be used above the thatch layer to remove dead and dying grass plants that will ultimately contribute to the thatch layer.
To produce upright grass prior to mowing to give a cleaner more consistent cut.
To control weeds and weed grasses without using harmful chemicals
Verticutting will also help remove annual meadow grass seed heads and promote finer grasses, such as bent and fescue.
