In a statement, Miss Roper's father, Adrian Roper, said he hoped concerns raised by an arboricultural consultant earlier in the inquest would be taken onboard.

“A lot of people do it because they think it’s going to enhance flowering, but it actually delays flowering onset as much as a month,” said Tom Smiley, senior arboricultural researcher at Bartlett Tree Research Laboratories in Charlotte.

The arboricultural report said the tree had been "in hazardous condition for several years, and prior to January 2018 at least three stems would have been clear threats to the railway".

After the two leaders departed, U.S. officials dug up the tree and isolated it in quarantine — the arboricultural version of family separation — and there it died.

As clamor built to save the tree, the garden retained an arboricultural consultant, James R. Clark, co-author of one of the tree trade’s standard textbooks.
