Coconuts fall at different stages of their life. We have 4 trees surrounding our home and we have a net around the trees which catches the fall of the coconuts. Also parking under a coconut tree is always risky, I have had my parked car along a road dented and windshield broken because of a falling coconut from the tree above. If I had noticed the tree that day (they curve a lot), I wouldn't have parked below.
