|Oak Wilt and Arborist Service
Tree Removals and Trenching Service
(Ceratocystis fagacearum) is a fungus that infects and grows in an oak
tree. Simply, the fungus clogs the tree's vascular (or vein) system and
the tree slowly wilts and dies without nutrition and water. Live oaks can
die within one to three months (though about 10% survive with various
degrees of damage). Red oaks and Spanish oaks usually do not survive
the infection. (information obtained from various sources).
The sign of Oak-Wilt infection in a red oak is wilting of the leaves (which
happens very quickly). The tree literally looks sick. An off season color
change in the leaves (to brown or brilliant color) could be another
indication of the fungus infection. In live oaks, there is a term called
"veinal necrosis" where the leaves are green but the veins are yellow or
brown. This is not an absolute but rather, a rule of thumb.
There is not a 100% effective cure for Oak-Wilt. While some treatments
have varying degrees of success, unfortunately infected trees can die or
never fully recover. Some infected trees survive on their own. There is
no one authority on oak wilt and opinions are changing.
You can protect your beautiful trees by painting pruning cuts and
removing infected or suspected trees (with proper identification). Oak wilt
can spread through the root systems of same specie trees where the
roots have grafted to each other. Oak-Wilt is estimated to move about 75
to 100 feet a year in this manner though there is plenty of room for
speculation. We can provide safe pruning and chipping like the picture
of our job below along the Medina River.
|We can help with Oak Wilt identification, tree removal, trenching,
planting of new trees, chipping, haul-off of dry wood, or set up burn piles
to remove the infected trees from your property and adjacent healthy
trees. We also work with other professionals who apply nutrition based
therapy to help strengthen the resistance of the trees adjacent to the oak

identification pictures of this potentially devestating disease.
