Suffering from draught

We took to Sweetheart's olive fields to check if the trees bear olives for the harvest next month... and most of them don't; they even dropped their leaves in order to survive the draught of the past half year. It's truely a sad sight how the olive grove is doing now. 
Sweetheart must have an irrigation system in his fields placed before coming Spring to help his trees survive coming Summer and years... in the area of Iraklion many hillsides have trees that turned brown and died off, because of the draught, and heat of the past three years.
