There are, likely, a few problems. I cannot see the soil, so I cannot confirm whether the plant is rootbound or not. That could be one of the issues.
If the plant is not fertilized, then this could be an issue, as well. Though it isn't important when the tree is young, as it ages the roots can deplete the soil of nutrients.
Proper pruning can help rejuvenate the plant, also, at this plant's age.
