An eTwinning project about olive oil. Students from the Vocational school of Ierapetra write about the olive tree.

1. By students from
1st EPAL Ierapetra’s

2. Introduction
 Olive trees can live for
hundreds of years. This is the
oldest tree in the area. The
maximum diameter of the
trunk is 4,9 m and the
circumference is 14,20 m.
Based on the method of
annual rings, it is estimated
that the tree was planted in
the period 1350-1100BC!

3. Planting
 They must be planted in
warm places that don’t
have much humidity.

4. Pruning
 They must be pruned
every year.

5. Watering
 Olive trees need
watering from May to
November.( Those
months it doesn’t rain on
Crete.)

6. Fertilizing
 You can fertilize the olive
trees in February or
March after picking the
olives with nitrogen,
potassium and
phosphorus. These
fertilizers don’t leave
traces in the olive oil.

7. Enemies
 The main enemy of the
olive tree is the fruit fly.
It is a fly that makes a
hole in the olive and lays
its eggs. When the eggs
hatch the worms eat the
olive. This affects the
quality of the olive oil.
Fruit
fly
Trap

8. Diseases
 The main disease that
the olive tree can be
affected by is a kind of
carcinoma. Lumps are
formed on the branches.

9. Picking the olives
 The olives are ripe to be
picked from December
to March. You use tools
like rods, nets and
generators.

10. Conclusion
 Like all living organisms,
olive trees need care so
that they can give us
their fruit and fresh olive
“juice”- olive oil.
