I find Papaya (Mexican) to be even more productive in SE Texas. I have a bunch of volunteer papaya plants that came up at the bases of Citrus trees around my orchard (from spreading compost from my huge compost bin). Some make it through our freezes and in their second or third year easily produce 50-100 pounds of fruit each. I started harvesting ripe fruit last October from just 3 “trees”:
I continued harvesting fruits every few days until January. In mid-January (just before the killer freeze) I harvested the largest of the nearly-ripe fruit from those 3 trees - over 180 pounds of it!
I gave away a bunch of it, and have been eating 1-2 papayas every day since. Here is what one of the (now multi-trunked due to repeated freezes knocking it back to a stump) plants looked like last fall:
Here is the stump on that 3-year-old papaya plant before the most recent freeze:
