Good for you propping up the tree and getting a big papaya! I've had them fall over too. One, just the top fell off. The rest tried to regrow but eventually died. I can't figure out papayas either, what makes some thrive and others not. Ive had some seedless ones too but they tasted just as good. I don't know what's up with that either. So many new things to figure out! It keeps every day interesting.
