Why you pack earth tightly around the root when planting trees?

Packing earth tightly around the roots when planting trees helps eliminate air pockets that can hinder root growth and water absorption. This ensures better soil contact, allowing roots to establish more effectively. Additionally, compacted soil provides stability for the tree, supporting it as it grows and develops. Overall, proper soil packing promotes healthier root systems and improves the tree's chances of thriving in its new environment.
