Thank you, i've updated my profile. I'm from Sydney, Australia.
The female flower issue I seem to have is they die off before they open from what I can see. When they are small and immature they start to turn white (so I think they are developing), then develop brown spots, go brown, then drop. I have been checking every morning because I heard the flowers open in the morning for a couple of hours so I want to catch them to hand pollinate.
I have had two females flowers a couple of week back but since then, nothing.
I'll hit the plant with another spray of copper fungicide, and I have had snails.
