This way it provides extra nutrients as well as an element that will help prevent important diseases, such as repilo or tuberculosis of the olive tree.

However, that doesn’t mean that’s the only time it should be applied. This should also be done after harvest. I mean, in the fall. At that time, due to the productivity he had, the trees will be more vulnerable, weak and it is possible that they lack nutrients and need to regenerate.
