TV star Tom Selleck plants a tree on his California ranch every time a close friend dies.
The actor decided on the gesture after crooner Dean Martin, who once owned the estate, died - and he has quickly created a mini forest of remembrance.
The former Magnum, P.I. star reveals, "I plant trees for people - oak trees, sycamores, California peppers.
"I planted a tree for Dean. And I planted one when my friend Frank Sinatra died. President Reagan and Nancy have a tree, because I knew them pretty well.
"On my own I've probably planted over 2,000 trees."
And the gesture appears to be paying off for the actor - his ranch has become a successful avocado farm.
