What's a Root Crown and Why Is It Important?

The root crown of a tree is the area where the below-ground parts of a tree meet the above-ground parts. Its placement is important and it should be at the ground level. If the placement is not correct, it can harm the long-term growth and the life of the tree. Unfortunately, the placement is often incorrect and during the nursery production, it may be over-potted and the root crown may be placed below the potting mix.

Some problems incorrect placement of the root crown can cause include:

Collar Rot

Collar rot is one of the most dangerous problem for trees. It can occur if the root crown is buried too deep. Collar rot is a fungal disease. Over time, the fungus will girdle the trunk, which prevents important nutrients and water from moving into the tree's vascular system and can cause death of the tree if not treated.

Girdling Roots

If the root crown is buried deeper than it should be, it can cause the tree to develop girdling roots. Girdling roots are roots at or slightly below the soil line that can wrap around the tree trunk "girdling" it. Girdling roots can cut into the main trunk and restrict water and nutrients between the roots and the branches of the tree.

Fibrous Roots

Fibrous roots can also form above the root crown and original rootball. This makes it difficult for water to get into the rootball causing a setback in tree growth or even a potential death because of moisture stress.
