What happens if you cut the surface roots of a pine tree but leave the tap root?

Cutting the surface roots of a pine tree can lead to significant stress for the tree, as these roots are crucial for water and nutrient absorption. While the tap root may provide some stability and access to deeper moisture, the tree may struggle to remain healthy without its surface roots. This can result in reduced growth, increased vulnerability to disease, and ultimately, the potential decline or death of the tree. It's generally advisable to avoid cutting any roots unless absolutely necessary.
