We used to own a property in Ovacik with a big garden and as we liked Olive trees we planted eight around it.It takes a few years for them to produce olive.You can have them pressed in a cooperative with you neighbours I believe.This gives you the quantity needed.We just gave a neighbour the olives.
We also had a larger property along in Koycegiz which had olives and fruit trees in the garden and when we were not there the neighbours would graze their goats there and we never saw what happened to the fruit and olives.This is Turkey!!!
The crops were being used and appreciated and that was very satisfying.Our neighbours would give us little gifts like salad or a pastry or some goats meat cooked meals.I don't think money is considered,it is more give and take in a courtesy level.Friendship of your neighbours in Turkey is very valuable,or anywhere come to that.I really don't think it would be a moneyspinner for anyone but maybe I am wrong.
