Which of the following is NOT involved in lawn care management?

Lawn care management primarily focuses on the cultivation and maintenance of grass and the overall health of the turf. Each activity mentioned contributes directly to the care and management of lawns.

Weed identification is crucial because it allows lawn care professionals to determine which species are present, enabling them to apply the appropriate control methods and maintain a healthy turf environment. Core aerifying helps alleviate soil compaction, allowing water, air, and nutrients to reach the roots more effectively, thus promoting healthier grass growth. Mowing is essential for managing lawn height, encouraging dense growth, and controlling weeds.

In contrast, pruning trees does not directly contribute to the management of lawn care. While it is an important task in landscaping and tree care, it pertains more to the maintenance of trees rather than the management of turfgrass. Therefore, this choice stands out as not being directly involved in lawn care management.
