How do you use cut after beating misty?

After defeating Misty, the Cerulean City Gym Leader in Pokémon, you can use the move Cut to access new areas. First, ensure you have obtained the Cut HM (Hidden Machine) and taught it to one of your Pokémon. Then, head to locations with small trees blocking paths, such as certain routes or areas in the game, and approach the tree. Select the Pokémon that knows Cut, and interact with the tree to clear it, allowing you to explore further.
