Mowing is important to maintain turfgrass because it maintains top growth within specified limits, controls undesirable vegetation intolerant to mowing, sustains turfgrasses, and produces a functional athletic surface for sports fields.
A standard rule in the industry for moderately to intensively maintained turfs is to never remove more than 1/3 of the grass blade in a single mowing. Removing more than 1/3 can result in poor plant health and growth. Mowing frequency is the number of mowings per unit time. Mowing frequency depends on turfgrass growth, level of maintenance, weather conditions, and climatic conditions.
