Hi. I bought an olive tree in March. It's a more mature one so wasn't cheap! It has developed peacock spot and I'm struggling to understand how to treat it. I have sprayed it with a copper mixture already. The peacock spots are still appearing. Will all the older leaves get infected and drop off? Also fruit is budding so should I pinch off the fruit to allow the plant the best chance of recovery? Any help or advice is much appreciated!
