If we talk about olive cultivation, June is a very interesting month for the development of the future olive fruit. Having had a remarkable fruit set, now is the time to balance the nutritional needs of the olive tree and provide all the energy necessary for the final fruit development. From now until  september, you have to water olive trees and eliminate the stems that grow on the trunks and that prevent the sap to the branches and fruits. Sometimes it is even necessary to re-fertilize the soil.
