Nope, the mangoes can grow bigger than our hand palm. I believed as they are cultured/genetically modified they are built this way.
I'm sharing a YT link here so you can get an idea of what I'm talking about.
This can be a real problem solver to modern agri and especially urban fruit production.
We learn something new every day! I never expected to see a mango growing on a tree that size.
When I go back to living in some city and not in a small town this will be an idea I would love to consider. Mango is one of my favorite fruits :)
