Level it up at Eterna Forest.
To evolve your Evee into Leafeon, get a leaf stone, and use it on Evee, and it will evolve into Leafeon! Have fun with Leafeon! -Garrett
You level up evee in eterna forest
You can't leafeon doesn't exist in leafgreen.
you can evolve evee to leafeon by taking leafeon to a stone in the forest by the second gym leader.
no have to trade from dppt
Get an Eevee and go to Eterna forest and level it up. You should have a Leafeon.
Glaceon: To get Glaceon you got to have an evee first then go to a route where in snows most likely stand next to a tree that has snow on it give the evee a rare candy and it should evolve to a Glaceon. Leafeon: To get Leafeon you got to have an evee first then go to a forest EX: Eterna forest then stand to a normal tree give the the evee a rare candy and it should evolve to a Leafeon. NO CHEATS!!!!!!!!!!!!!!!!!!!!:)
In the woods before Eterna, there is a Mossy Rock, you must have an Evee with you and a rare candy, stand next to it and level up the Evee and it will evolve to Leafeon.
Evee will never evolve to leafeon in firered because leafeon wasn't created until diamond, pearl and platinum came out meaning it doesn't exist in firered.
you can't. there's no moss-stone to evolve it, so you'll need to trade it from diamond, pearl or platinum
you have to take it into the eterna forest, find the moss covered rock and level up your eevee there. then it will evolve into leafeon.
eevee can evolve into vaporeon, jolteon, flareon, espeon, umbreon, leafeon, and glacieon.
