The organic matter produced by mulching retains the moisture in the soil during summer. This creates a temperature and moisture buffer and the plants are protected against heat, which, in turn, protects the lawn from drying out. As a result, there is less need for watering. If the sward produces too much biomass (clippings), it can also negatively affect the sward! Make sure the grass cuttings are sufficiently small. Slow-growing plants make this easier.
Your lawn will be healthier
According to a study by Prof. Dr. Karl-Ernst Schönthaler of the Vienna University of Soil Culture, a mulched lawn looks more vital, has a denser sward and the grass is a more beautiful green. In addition, this research demonstrated that soil organisms in the soil under mulched grass are 40 percent more active. This allows the soil to breathe better. Moreover, the added nutrients strengthen the lawn, giving weeds and moss less chance to grow.
