Spring time flowers on the olive tree are white and quite insignificant but each tiny bud holds the promise of a fruit maturing in the winter sun.
Our neighbours tell us that a major pest which can prevent the tree fruiting is the ant.
If you look carefully you can see the tiny olive blossom.
In this part of Spain nurserymen often quote the price of olive trees as €1 per year of growth; they will happily show you trees (they estimate) of 1000 years of age at the corresponding price of €1000.
We chose to grow our own from seedlings and now have small established trees.
