Berries are extremely helpful items in the game. Pokémon can hold them so their effect is used in battle. To pick berries go to a patch of loamy soil and press to pluck them. You can also plant them using on a patch of soil. Using the Wailmer Pail you can access the grown berries more quickly. Berries can also be blended to give Pokémon special abilities in Pokémon Contests. In FireRed and LeafGreen, berries can also be mixed. In Ruby and Sapphire, a glitch occurs after playing for 100 hours that causes all time events including growing berries to stop. To get rid of this event, trade your game for a newer Pokémon game.
