Oak Wilt Update From The Clinic

Oak wilt is a disease caused by the fungal organism Bretziella fagacearum. The disease can spread both underground and above ground. The disease is spread underground to healthy oaks through the root system of infected oak trees. Additionally, sap-sucking beetles can be attracted to the fungal mats that form under the bark of infected, dead oaks and can spread the disease above ground as they move to uninfected oaks.

Tips on Oak Tips

Late-season defoliation of established deciduous trees is not usually of great concern. There is little impact on overall tree health because trees have produced and stored enough carbohydrates to support leaf production next spring. Indeed, we’re close to the time of the year when deciduous trees drop their leaves anyway.
