Mulch (Japanese: こやし Fertilizer) is a type of item introduced in Generation IV. Mulch may be used before planting Berries in soft soil to promote healthy Berry growth in various ways. Mulch has no use in battle (aside from being thrown with Fling, in which case the move will have 30 Power).

If more than one Mulch is spread on one patch of soil, only the effect of the most recently used one will apply. According to the lady in the Berry Master's house in Sinnoh, Mulch is made "by mixing high-grade soil with Poké know..."

Mulch can be bought from the girl in the Berry Master's house on Route 208, or in the Goldenrod Flower Shop after acquiring the Berry Pots.

Due to the lack of soft soil in the Unova region and the fact that the Berry Pots are not obtainable, Mulch is a valuable item in Pokémon Black and White. In Pokémon Black 2 and White 2, Mulch can be sold to a Pokémon Breeder at the end of Mistralton City's runway for $1000 each.

In Pokémon X and Y, Mulch can be acquired from one of the Berry fields composters. By putting in different combinations of Berries, different kinds of Mulch can be produced. If traded to Pokémon Omega Ruby and Alpha Sapphire, Mulch cannot be used, as the soil is unsuitable for Mulch.

  • Because some Mulch can alter a Berry's growth rate, it is possible for some Berries with different base growth times to grow in the same amount of time. Similarly, Berries with the same base growth time can vary in actual growth time.
  • Inside the Berry Master's house there is a book titled "Much Ado About Mulch: A Berry-Grower's Guide". The title of this book is based on William Shakespeare's "Much Ado About Nothing".
