I have planted two olive trees. One in sandy soil and the other in clay--though heavily organic. One of them has grown to about twelve feet tall in a year! I had to laugh when the internet warned that they are an extremely slow-growing tree. Clearly the heat and sun is not harming it. My question: can I expect them to set fruit? We get a low of 14C/57F in the winter at night, and highs of 46C/115F in the summer. If I can expect to get decent production out of them then it would be worth investing in on a large scale judging by the growth of these first ones.
