This Mango Tree is about 6 years old from what I have been told from the previous owners. It gave 4 Mango's last summer and none at all this year. Based on the pictures please give me advice on how to clean up and treat the tree so it will give fruit. There is a Mango tree in the yard next door that used to give tonssss of mangos then they cut it really bare and this season it only gave about 10 fruit. Does this have any connection with my tree? Also, the drainage for the washer leads in that area right now, the water is well drained but keeps the area damp sometimes. Plus there is a sprinkler system. Is the soapy water harmful? I am new to gardening any advice would be helpful. Thanks :-)
