Responding to social media posts, Mr Macron said people should not read symbols into everything.
Trump and Macron planted the tree with their wives watching on but it was not in the lawns of the White House for long as it was soon placed in quarantine due to national law regarding the potential introduction of parasites.
He then promised to send another oak from the Belleau Wood in northern France, where more than 1,800 American soldiers died in a key World War I battle in 1918.
As Macron wrote on Twitter at the time, the tree "will be a reminder at the White House of these ties that bind us". "We have disagreements but we continue working together", TASS cited the French leader as saying.
"It turns out that this oak was put in quarantine for American sanitary reasons and the poor thing did not survive", Macron said.
It died in quarantine after being dug up.
Macron confirmed that the tree had died but said there was no tragedy. "Of course. Because I think we need someone strong".
Concerned over the security of Europe, Macron has also been critical over Trump's decision to withdraw from the decades-old Intermediate-Range Nuclear Forces Treaty (INF), which banned the ground-launched missiles with a range between 500 and 5,500 kilometers.
"I think that chaos is here".
