What’s a Root Crown and Why is it Important?

The root crown of a tree references 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 not always correct and during the nursery production, it may be over-potted and the root crown may be placed below the potting mix.

Here are some problems incorrect placement of the root crown can cause.

Collar Rot

Collar rot isn’t as common as some of the other potential problems, but it can occur if the root crown is buried too deep. This means the buried bark and cambium of the tree would essentially rot, making the tree ringbarked. Ultimately, this can cause the tree to die.

Girdled Roots

If the root grown is buried deeper than it should be, it can cause the roots to grow upwards. This means new roots towards the base of the stem receive additional water, causing them to grow rapidly. This can cause girdled roots and expansion of the roots and trunk of the tree can cause it to die.

Fibrous Roots

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