> Palms begin to bear fruit in 4 to 5 years and reach full bearing at 10 to 15 years, yielding 40 to 80 kg (90 to 180 pounds) or more each.

But I've also read that some dates won't also bear fruit or something like that? Like how some trees are male and need some female to fruit or vice versa. Maybe its a climate thing too, we're on tropical climate.

Any first-hand experience about dates?

Our date trees are already 5 to 6 years old and are as tall as 8 to 9 feet but they havent shown any fruits or flowering?
