So that your lawn enters the winter phase well cared for, you can scarify or aerate it again. By scarifying, you remove unwanted moss which has grown in summer. If moss and lawn thatch are removed, the lower parts of the grass receive more air and light again. The individual grass plants can then develop better. Fertiliser gets into the roots again and does not feed the moss and decomposing bacteria between the lawn thatch. In addition, scarifying helps combat weeds. However, scarifying should not be carried out too intensively, especially in autumn, as the grass growth slows down. Any gaps created by scarifying can then no longer close up. Frugal weed types may then in turn grow in these gaps.
Mow the lawn before scarifying. Set the scarifier so that the blades do not penetrate the soil too deeply but simply remove the top layer of lawn thatch. After scarifying, you can lime or fertilise if necessary. Where large gaps appear, you must re-sow in spring.
If you regard scarifying as too intensive for your lawn, you can also aerate it before winter. With aerating, steel springs comb the surface of the lawn without penetrating the soil too deeply. Unwanted moss and lawn thatch is thus removed. The lawn roots receive more air, water and nutrients again. In addition, the soil is slightly loosened, so that the grass roots can develop and spread better.
