The stages of the annual cycle of the olive tree
It's interesting to know the stage or state of growth in which you find an olive tree, this way we can tell the period in which the olive grove is, which is very important in order to provide appropriate treatment for potential diseases, and thus obtain the most effectiveness from them. But keep in mind that all the olive trees do not go through exactly the same phases at exactly the same time, they can vary slightly.
Before the ripening of the fruit, the olive tree goes through 10 phases:
- PHASE 1:Winter bud. At this stage the buds of olive trees have short stems, are acute and fully closed.
We can see that the bud is completely closed.
- PHASE 2: Sprouting. During this period the buds fatten, the stalk begins to elongate and the formation of the flower cluster begins.
In this case we can see how the buds get fatter.
The stage where we can see the calyx.
- PHASE 4: The corolla. This is divided into two sub-phases:
a) Formation and prevalence of the corolla. You begin to see the corolla, the calyx is opens out and the flower bud inflates.
b) Changing the color of the corolla. The flower bud continues to increase in size and the corolla color changes from green to light yellow (almost white).
In this stage we can see the corolla.
- PHASE 5: Stamens come out. The flower bud continues to grow and the corolla begins to open, so we can see the stamens.
As the corolla opens we can see the stamens.
- PHASE 6: Flowering. This is divided into two sub-phases:
a) Beginning of flowering. The first flowers begin to open, until they are completely open.
b) The full bloom. All or almost all the flowers are open, so you can see the pollen.
In this stage all the flowers are open.
- PHASE 7: Blossom. The ovary is fertilized, it grows. You can see the olive. All the petals begin to wilt and eventually fall.
In this stage the olive starts to jell.
- PHASE 8: Pit hardening. The fruit grows, to approximately half its size. The pit begins to take woody aspect, providing resistance to being cut.
The fruit grows up to half its size.
- PHASE 9: Veraison. The fruit reaches full size and some strips start to change to a different color which then spread until the whole fruit changes colour.
- PHASE 10: Fruit ripening. The olive reaches full maturity, so it can come loose from the stalk. Once the fruit ripens it begins its winter rest.
In this stage the olives drops off the stalk.
