Types of olives
The olive tree is a perennial, evergreen tree, with its height ranging from 5 to 20 meters. 30 olive varieties have been recorded in all 5 continents where olive trees are found. However, olive trees mostly grow in the temperate and subtropical zones where conditions are more favorable for them. In our country, olive trees blossom from late April to May.
There are several olive varieties and the distinction is made based on olive leaves, fruit and stones. 'Koroneiki' variety is used in olive oil production whereas 'Kalamon' is preserved as edible. Finally, 'koutsourelia' is used in olive oil production and can also be preserved as edible.
Olive trees can be planted from November to February and they need regular watering in order for the tree to yield as much fruit as possible.
As soon as the olive fruit is mature, it must be harvested. The primary characteristic that distinguishes immature fruit from mature fruit is their color that turns from green to black.
Factors that affect maturation time are the olive variety, the intended use of the fruit as well as a combination of the soil and climate conditions.
