Mr Obama will arrive in India on Saturday for the first leg of an Asian tour.
But as well as the usual security measures that come with welcoming a a visiting dignitary, Indian authorities have decided to go one step further, by removing all natural threats to the president as well.
All coconuts around the city's Gandhi museum, one of Mr Obama's stops in the city, are being taken down.
Mani Bhavan, where Mahatma Gandhi stayed during his freedom struggle against the British, is among five places the US president is visiting in Mumbai.
"We told the authorities to remove the dry coconuts from trees near the building. Why take a chance?" Mani Bhavan's executive secretary, Meghshyam Ajgaonkar, told the BBC.
