Cornell Cooperative Extension has sent out another notice about Oak Wilt, which was found earlier this summer in the Town of Islip. Since the original notice over the summer, more and more accounts of Oak Wilt have been happening in other towns within Suffolk County. The DEC is urging homeowners to prune their oak trees during the winter and not during growing season. “One way that oak wilt spreads is through insects (sap beetles are one of the main culprits), which can move the fungus from an infected tree to a healthy tree. During the warmer growing season sap beetles are active and attracted to the fresh wounds, increasing the chances of disease spread.” So be on the lookout! You can read more on the DEC’s website here.
