Help with rotting guavas

[M5thfl]

Hello, I posted earlier but now I can't find the post. I have an unknown variety of guava bush growing in my yard. Last year and this year the fruit starts rotting on the bush while it's green. Can someone let me know what to do next year so it doesn't happen again?
Thank you!

If they are full of worms you need to bag them. My first thought is carib fly.

Did you ever get fruit that were not damaged/rotting?  If so, did it ever color up?

The bush was here when we moved in a couple years ago.
So what do I do if it's carob fly?

Could it be overripe?

Protect with bags

These can handle plenty of water so you don't have to worry about root rot. They also react well to very heavy pruning so shape it how you like and tip prune as the branches grow to make it bushier. I would put down a heavy layer of mulch as well and just keep it off the trunk. You can make it like a foot deep. Unless you want to drench it weekly with insecticide I would just bag the fruits if you find maggots in the fruit.
