7-year-old curly willow (BC, Canada) has dead central trunk to top, cracked/peeling bark at base. Arborist care history. Expert suspects internal wood rot from old wound.
Fungi enter wounds, decay wood slowly. Tree walls off infection. Eventually: more dead branches, structural failure in storms. No cure. Fertilize/water to slow progression.
Monitor until hazard risk, then remove. For replacement: consult local forestry/nursery for Okanagan Valley species (consider space, soil, water, power lines). Provided USDA tree care publication link.
