How do you tell when a mature white oak is dying?

A mature white oak may show signs of dying through several indicators. Look for excessive leaf drop, discoloration of leaves (yellowing or browning), and a decline in overall foliage density. Additionally, cracks in the bark, fungal growth at the base of the tree, or dead branches can signify poor health. Finally, if the tree exhibits poor growth or stunted development despite adequate conditions, it may be a sign of decline.
