watering olive trees
We have a beautful old olive tree which is the focal point of our view from the villa. Unfortunately it has suddenly (over the past 4 months) started to look very sad, many leaves have dropped off and the remaining ones are yellowing, although it does have quite a few olives. Our gardener thinks it need watering as a year ago we paved the area around the olive. All our other olive trees are fine - has anyone experienced this with an olive tree before?
