I have a couple of guava trees but my tallest and oldest has recently had its leaves develop tiny holes on its leaves. I cant find any bugs or anything on it. It is slowly starting to show on more leaves now and its worrying me. What is the cause of this? If anyone can tell me what causes it, i will appreciate it.
If you have guava trees, what do you fertilize it with? What can i spray on it? Can you spray it with neem oil or liquid iron?
