An investigation by the HSE found a large limb had fallen from the tree in September 2019.
But no investigation was carried out to see whether the tree posed a future risk.
Mr Hall’s son Sam said the last four years had been “a long, painful trail – a path we never wanted to be on”.
He added: “Losing dad was losing my life and strength. I miss every little piece of him – his laughter, wisdom, and adventures we shared.
“Our travels ignited a passion in me, but now every journey feels bittersweet without him.”
HSE inspector Lorna Sherlock said: “This was an utterly tragic event that has caused the death of a much-loved husband and father.
“Had this public area been better managed, this death might have been avoided. No lessons were learned from the limb falling off the tree less than a year before.
“Cheshire East Council had not adopted a formal overarching tree strategy to manage the risks from trees in public places since it was formed in 2009.
“There was no overarching, consistent risk identification process leading to zoning of trees in all frequently accessed public areas.
“Fiona and the family have shown great courage and fortitude throughout their ordeal.”
