If it's not dying, then it sure look very very depressed or close to dying. Just recently bought a carrie mango tree in a 5 gallon container with some bloom. I repotted it in a 15 gallon not long after purchasing it in potting soil and mulch. Then started noticing all the bloom became brown/died, so i spread some copper fungicide. Well now the leaves are dropping and the blooms are history, and the leaves that are on the tree look like they're on their last leg... any idea??
