Which one of these is a method of managing turf health to control weed growth?

Managing turf health is essential for creating a strong environment that can naturally suppress weed growth. Regular aeration and watering are effective practices in achieving this.

Aeration involves removing small plugs of soil from the lawn, which helps alleviate compaction, enhances root growth, and allows for better penetration of air, water, and nutrients to the turf grass roots. This encourages the development of a robust and healthy lawn, making it more competitive against weeds.

Regular watering is equally important, as it ensures that the turf grass receives adequate moisture to thrive. Healthy, well-watered grass can develop deep roots, which helps it outcompete weeds for water and nutrients. Together, these methods promote overall turf vigor, making it less susceptible to weed infestation.

In contrast, frequent compacting of soil can damage turf health, limit root growth, and create an environment conducive to weed establishment. Limiting sunlight directly contradicts the needs of grass species, which require light for photosynthesis. Applying heavy fertilizers might encourage rapid growth of grass but can also lead to excess nutrient levels that can promote the growth of weeds if not properly managed.
