Your olive tree was just in full bloom, now it is producing its first fruits, you are so happy and suddenly yellow leaves appear. Panic quickly spreads, especially among young olive tree owners.
But there is no reason to worry.

Yellow leaves are completely normal in summer, after flowering. Our olive trees are evergreen trees, which means they do not lose all their leaves at once in autumn, like most native trees.
An olive leaf has a lifespan of about three years. This makes the olive very tolerant of drought because it uses its resources sparingly and does not have to regenerate the entire leaf mass year after year, but renews it in stages to save water and nutrients.
After flowering, the time has come for our olives to start this process. It is the time when our trees only need very little water and put all their resources into fruit formation in order to generate new shoots in the autumn on which the fruit for the following year hangs.
