Which of the following is NOT a proper cultural practice for maintaining healthy turfgrass?

Infrequent mowing is not a proper cultural practice for maintaining healthy turfgrass. Regular mowing is essential for promoting dense and healthy growth in turfgrass. When mowing is infrequent, the grass can grow too tall, leading to several adverse effects, including increased susceptibility to pests and diseases, shading of lower leaves, and a poor overall appearance.

In contrast, high-quality seed selection, proper fertilization, and regular watering are all vital cultural practices that contribute to the health of turfgrass. High-quality seeds ensure that the turf is resilient and suited to the local environment, while proper fertilization provides necessary nutrients for growth. Regular watering helps maintain adequate moisture, which is crucial for the overall vitality of the grass. By adhering to a routine of frequent, appropriate mowing, along with these other practices, turfgrass can thrive and resist environmental stressors more effectively.
