What causes oak wilt?

Oak wilt is caused by a fungus called Ceratocystis fagacearum. This fungus is spread through the movement of sap from infected trees to healthy trees. Sap can be moved between trees through root grafts, wounds, or pruning cuts.

How is oak wilt spread?

Oak wilt is spread through the movement of sap from infected trees to healthy trees. Sap can be moved between trees through root grafts, wounds, or pruning cuts.

Root grafts: Oak trees that are in close proximity to each other can form root grafts, which are connections between the roots of two trees. If one tree is infected with oak wilt, the fungus can spread to the other tree through the root grafts.
Wounds: Oak trees can become infected with oak wilt if they are injured. This can happen if they are damaged by storms, construction, or other activities. If the wound is deep enough to reach the tree’s vascular system, the fungus can enter the tree and cause infection.
Pruning cuts: Pruning cuts can also provide a way for oak wilt to enter a tree. If the pruning cut is deep enough to reach the tree’s vascular system, the fungus can enter the tree and cause infection.

How can I prevent oak wilt?

There are a few things you can do to help prevent oak wilt from infecting your trees:

Avoid planting oak trees in areas where oak wilt is known to occur.
Keep trees healthy by watering them regularly, fertilizing them, and pruning them properly.
Avoid damaging trees by mowing over them, driving over them, or causing other injuries.
