Beware of Oak Wilt...

Oak Wilt is caused by a fungus that enters the tree and stops the flow of water and elements by plugging the vessels in the vascular system.

Some species of oaks are more tolerant than others, even though all are susceptible. Red Oaks are highly susceptible while oaks in the White Oak family are more tolerant of an infection. The first symptom in the Red Oak family is an oily green appearance in sections of the tree's canopy, quickly turning a tan or red color. A heavy and rapid shedding of foliage with individual leaves displaying these symptoms is another indication.  However, this may not be the case in the months of February and March, as this is the normal process of leaf shedding during these months. 

Oak Wilt spreads from tree to tree by root-to-root contact as a general rule. Overland spread is another method of possible contamination.  Sap-feeding nitidulid beetles can carry spores from fungal spore mats on a dying Red Oak to a wound on a nearby tree. The spores can infect the tree only if the wound is fresh and created in the previous 24-48 hours. 

Oak Wilt can expand 75 feet or more in a dense group of live oaks. In a rural area, trenching between infected and non-infected trees can eliminate the disease. This is more difficult in an urban area due to underground utilities and other obstructions.
