Second-class mango trees tend to be medium-sized and prosperous, with wide and drooping leaves, soft and slender branches, tower-shaped crown, convenient pruning and shaping, beautiful crown and easy management.

3. fruiting time: a mango can bear fruit many times a year, and it can blossom and bear fruit in the third year after planting.
