It evolves with Leaf stone.
the only way to evolve a exeggcute is to give it a leaf stone. i hope this helped!
Exeggcute evolves when you use a leaf stone on it.
Exeggcute doesn't evolve by levelling up. It evolves into Exeggcutor when exposed to a Leaf Stone.
exegutor does not evolve only exeggcute evoles
Exeggcute will evolve at any level since you need to use a Leaf Stone on it in order to evolve.
you have to trade it to evolve.
