Did you know pruning your oak trees right now could actually kill them? Experts are warning that a sneaky fungus called oak wilt is spreading fast in Ontario (and beyond!), wiping out red oaks in just weeks. Beetles carry the fungus to fresh wounds, so if you have oaks, skip the pruning until November and seal any cuts ASAP. Losing these trees would be a disaster for our neighborhoods and forests. Keep an eye out for wilting, bronzed leaves, or a weird fruity smell! #OakWilt #TreeCare #InvasiveSpecies #Science
