I would like to know if I can use olive trees to make a tall thick hedge. Also what would be a good variety to hedge and the optimal distance apart for planting. I am looking a creating a fence extension screen, as such the olive trees would be planted in a raised brick garden bed adjacent to a 6 foot high brick wall, thus lifting the height of the tree, then I would like to grow tall straight stems/trucks and allow the foliage at the top of the trees to form a dense hedge. Thanks Nick
What you are looking at doing is called a "pleached" hedge. It has been done for centuries and makes a fantastic looking hedge. Olive trees are perfect for this purpose. They are tough and when pruned create nice thick foliage. I would suggest using a variety called "Mission" it has small leaves and branches well. It still will produce fruit, every variety I can think of does this, but the amount of fruit will be limited due to regular pruning.
