Oak wilt spreads to other oak trees in two ways – long distances with the aid of certain beetles or locally through common or grafted roots. Once infected the tree has limited time before the vascular system becomes constricted which causes death to the tree. Certified arborist Sam Hanson is available for consultation to discuss treatment options. Primarily we use microinjection or macro-infusion with Alamo®.
