Dotted around the Hoenn region, you will find loamy soil, many of which are housing berries. Once you have picked the berries, then you have the ability to use that loamy soil to grow your own berries. These can be any berry and will require attention to get the best crop.

Growing berries works the same as before. Once you get the Wailmer Pail, you'll be able to water the areas too, to keep the soil moist and thus increase the potential yield of the berries. They dry up after every 4 hours.. The mulch from X & Y does not make a return. The berry growth time and yield is different from Pokémon X & Y also.

A returning feature involving berries is the ability to create PokéBlocks. Using the berries, you can use between two and four berries to create PokéBlocks. These are then created based on the contest type of the berry and each berry has a small chance of making the PokéBlock into a PokéBlock +, which gives it double the stat increasing power
