Berry farming

[Progfan_r]

I am not familiar with the berry farming mechanics of Pokemon Reborn.

 

1. Which generation berry mechanics does Reborn follow?
2. Is there a guide available somewhere?
3. If not, can someone explain it here?

 

I am particularly focused on maximizing the number of berries I have in the quickest way possible.

Pokémon Reborn uses Gen 4 Berry Mechanics, although there might be some tweaks. I don't know if there is a guide somewhere, but most of the Bulbapedia article should apply. In general you want to keep your plants watered, as it increases the yield. Reborn also doesn't have repeatable methods to get mulch, so you cannot use those, unfortunately. 

As for where you can grow berries, there are some spots in the Aventurine Forest on Route 1, and once you've restored the city some much more convenient spots in Lapis Ward (where the Aqua Hideout used to be), South Obsidia Ward (once the slums are renovated) and the Malchous Forest. 
You can buy the Wailmer Pail from the Sweet Scent shop in Lapis Ward, and the berries themselves from a few different places, including all of the soil spots and the Obsidia Department Store. You can look up where to find everything in this item guide.
