What is the correct technique for planting a tree?

The technique of digging a hole twice the width of the root ball is crucial for ensuring that the tree has ample space to grow and establish itself in its new environment. This method allows for the root system to spread out and encourages stronger growth. When the hole is wider than the root ball, it also helps to break up compacted soil and provides a better aeration and drainage characteristic, which are essential for root health.

In addition, this technique helps to prevent issues such as girdling roots, where the roots circle the trunk instead of growing outward, and provides an area where roots can easily penetrate the surrounding soil. Proper spacing encourages the integration of the tree’s roots with the native soil, promoting healthier growth and stability.

Choosing to dig a hole that is only slightly larger than the root ball, planting at higher elevations, or using artificial supplements can lead to poor establishment of the tree, nutrient deficiencies, or even root suffocation. Therefore, digging a hole twice the width of the root ball is widely accepted as the best practice for planting trees successfully.
