Thanks for the pic of the fully ripened one - that is definitely what I expected them to look like when ripe. Mine definitely are not ripe, and not ripe enough to mature properly on the counter either - just starting to wrinkle & are still very sour. Still white about half way in to the flesh when I cut them open. I've left one to ripen in my garage just to see - but expect it will not ripen properly. The others I made into green mango pickles which I like.
I've only got 3 left on the tree - really hope one will ripen properly so I get to taste it this season. When racoons pull them off the tree, there are usually some claw marks on the fruit. But none of these have been marred, so I'm wondering if they are dropping for some other reason? It is much hotter than usual for this time of year & no rain - will trees drop fruit with lack of water? I wonder if I should hand water the tree? My manilita & pickering are both loaded with fruit at about the same level of maturity and they are not dropping fruit. Thoughts?
