Will post some more photos later.

I am South East QLD. I have no idea how many vines there are, as I just let them grow wild. Rough math, I planted them in a 4 by 4 grid, and there were roughly 2 vines that grew from each spot. So maybe 32?

The leaves started to die off, so decided to harvest the ripe melons just in case they got infested by something.
