Frequently Asked Questions

What factors influence the ideal height for cutting grass?

The ideal height for cutting grass depends on several factors, including the type of grass, the season, and the local climate. Different grass species have different optimal heights for healthy growth. For example, cool-season grasses typically grow best when cut to a height of 2.5 to 4 inches, while warm-season grasses thrive at 1.5 to 3 inches.

How does cutting grass too short affect its health?

Cutting grass too short can lead to several health problems for the lawn. It increases the risk of weed infestations, as shorter grass provides less shade for the soil. Additionally, grass that is cut too short may struggle to photosynthesize effectively, leading to weak roots and overall poor health.
