Just so, how often do olive trees produce fruit?

Young and Bitter. If you've provided your olive tree with a happy home, it will begin to bear fruit when it's around five years old. Bear in mind, however, that it's perfectly normal for olive trees to produce fruit only every other year, or to produce alternating heavy and light crops from year to year.

Subsequently, question is, do you need two olive trees to produce fruit? Many varieties of olive trees require cross-pollination but most the varieties that we sell do not because they are self pollinating or self-fruitful. They need another tree or sometimes two other trees for pollination, not of the same variety, but a different variety of the same fruit.

Hereof, why is my olive tree not fruiting?

Pollination Problems Olives are generally considered "self-fertile," meaning they do not require the pollen of another tree in order to set fruit. Because the trees are wind-pollinated, heavy rain during the flowering period can prevent pollination from occurring.

How long do olive trees last?

Provided with the appropriate growing conditions, this tree can survive in relative neglect for hundreds of years. While olive trees may live to be as old as 1,500 years, the average lifespan is 500 years.
