I'm loving Chris from Truly Tropical's YouTube channel. Great information here. Latest upload: How to know when to pick your Carrie Mango
https://youtu.be/3mYi8osFXkYIn a nutshell look for (in no particular order):
1. Color change- from green to yellow
2. Smooth skin
3. Plump fruit
4. Browning on the stem
5. Sap lines/marks
Doesn't have to be all the above. But should be at least a couple.
-Hopefully others can share if these tips also play out for those in Carrie's family tree (Angie, etc. )
