What common technique is used to promote healthy lawns?

1. Overseeding

2. Aeration

3. Fertilizing

4. Mulching

The correct answer is: Aeration

Aeration is a common technique used to promote healthy lawns by improving soil structure and enhancing the growth of grass roots. This process involves creating small holes in the soil to alleviate compaction, allowing air, water, and nutrients to penetrate deeper into the root zone. When soil becomes compacted, it can restrict root growth and prevent essential resources from reaching the grass, leading to a weak and unhealthy lawn. By aerating the lawn, you create an ideal environment for roots to expand, which can ultimately enhance the overall health and appearance of the grass. Additionally, aeration can help with thatch management, as it allows for better decomposition of organic matter at the soil surface. This technique is particularly beneficial for lawns that experience heavy foot traffic or have been subjected to drought conditions.
