I have a fairly large mango tree in the back corner of my yard that I grew from a seed. 10, maybe 15 years old now. It's starting to overhang my 10' tall Marsh Grapefruit, so I have been getting a little tired of waiting for it to bloom. I decided I'd give it one more year. I knew when I planted the seed the odds were against the fruit being any good, so probably no big loss if I cut it down.
Well, the tree must have read my mind. It finally bloomed and set fruit. Three of them. I need to bag them to protect from insects, but there's not much I can do about raccoons or squirrels or bears. Regardless, this is it's last chance. If the animals get them or they aren't really great, the tree is history.
