Bahia grass should be mowed regularly to maintain a height of 2-4 inches. Avoid cutting the grass too low as it will stress the plant and make it more susceptible to diseases and pests. It is best to mow the grass when it is dry. Also, remove weeds and debris regularly to keep the lawn healthy. If there are areas with dense growth, dethatching may be necessary. However, Bahia grass does not require regular pruning as it grows naturally in a low, spreading habit.
