The root-heaved post stops lifting the line
When a mature maple or oak root grows under a post it lifts and cocks it, and the lean spreads down the run. Cutting the picket loose and shimming does nothing — the root is still there. We hand-dig around the root, relocate or re-set the footing where the root will not lever it again, and pour a proper 36-inch base. The post holds because we worked with the tree instead of pretending it was not there.
