Mowing and fertilizing a commercial lawn should be done on a regular basis to ensure optimal health. Mowing frequency will depend on the type of grass, weather conditions, and amount of foot traffic it receives. Generally speaking, mowing should take place every 7-10 days during the growing season (April – October). Fertilizer applications should occur at least once per month in order to promote growth and maintain healthy turf. Following label directions when applying fertilizer is essential, as over-fertilization can lead to nutrient runoff into local water sources.
