If it's just one tree and you can reach, spray the mangoes with chilli water
made by boiling a few really hot chillis then straining the water. Possums
hate it and it will do no harm to the mangoes.

I have a small mango tree with a rapidly reducing number of mangos. The
mangoes are not yey ripe, but already the possums have eaten about three
quarters of the crop. The amngoes are reddening on the top.

Can they be picked at this stage, and left to ripen inside?
