Hi again, I updated by profile and posted on the new members board.
I have also uploaded some picture, below are the links.

When they were planted, no special fertilizer was added. Then I read online and I learned that I need a special NPK mix, so I went out and got some custom made fertilizer from a local Organic factory. I then dug about an inch deep around the plant and mixed that fertilizer with the soil plus some Vermi then flattened it back and watered normally. At some point also I found spots on my Fig tree, so I read its Fig rust or something called leaf miners; I got Neem oil and sprayed the whole garden including the banana and now no more fig rust.
I have let my gardener go as he did not spot or help on any of this, so i decided to read up and become an expert gardener myself
Did I do something wrong?
