Growing Berries
Berries can be planted in any empty patch of soft soil. The soil that the Berry was planted in will start out dry and can be watered by the player, the soil may dry up over time depending on the mulch and Berry used. Weeds and Pokémon may appear around the Berry tree which changes the amount of Berries depending on whether they are dealt with.
Mulch can be made by placing three Berries in the composters. Three Mulches are produced each time, and the type of Mulch produced is based on the colours of the Berries.
Mutation
Mutation will sometimes occur when two different types of Berries are placed next to each other. Once a certain mutation has been performed once, the formula for it can be reviewed with the Scientist in the Berry grower's hut. Using Surprise Mulch or Amaze Mulch on the trees involved increases the chance of a mutation.
