Just reporting that I have harvested multiple fruits from my 5 papaya trees. Not even one infested since the one I reported last time. So organza bags are such a great solution. So convenient. I have eaten copious amounts of green papaya salad this season. As pineislander noticed, fruit flies do not attack now. The newly formed fruits do not have injuries.
I will be updating this thread from time to time as I planted some other varieties, such as sunrise, sunset, tainung waimanalo low bearing, red lady, improved maradol, red matador, Sun Gold, known you, bella, red queen. At first, I was labeling them but lost patience somewhere on the way lol.
Quite surprising for me: some papayas started fruiting 6 months after planing the seed.
