Let it turn a little yellow on the tree and then pick it. Mango will have best flavor and sweetness if left to ripen on tree. We have found choc anon to last a long time in the refrigerator if ripened to full yellow before putting it in. It will last 3-4 weeks in fridge and will wrinkle but will not lose its flavor. IOW, it has good shelf life. We really like our choc anon, very productive, tasty little fruit. Have not had any off season bloom or fruit yet though...
