Obtainability
Berry trees
Berries are principally obtained by harvesting them from berry trees, which can be found in most tillage-viable areas—namely routes and forests, wherein most berry-tree allotments can be found.
Berry trees are monoproductional, meaning that they will return the exact-same berry archetype each time it grows. Most berry trees will regrow after three real-world days have elapsed; the only outlier to that is the EV-berry trees, which regrow after 4 days.
EV Reduction Berry trees
There are 3 locations where you can find EV Reduction berries out in the open:
- Viridian Maze where you can find all 6 of these berries
- Route 115 where you can find Kelpsy, Tamato and Pomeg berries (Attack, Speed, HP).
- Route 212 North where you can find Qualot and Hondew berries (Defence, Sp. Attack).
- Route 218 where you can find Grepa and Qualot berries (Sp. Defence, Defence).
- Route 224 where you can find Grepa berries (Sp. Defence).
- Route 228 where you can find Grepa and Pomeg berries (Sp. Defence, HP).
Berry Tower
- Main article: Berry Tower
The Berry Tower is one of the most prolific hotbeds for berry-obtaining, as they reward its challengers with EV-reductive berries. The only one currently available is stationed on Route 13 in Kanto. The tower offers 2 different challenges that reward berries:
- Normal challenge. The challenger must enter with pokemon of level 50 or below. All NPC trainers of the challenge have pokemon at level 30.
- Elite challenge. The challenger has no limitations on his pokemon. All NPC trainers of the challenge have pokemon at level 75.
The Berry Tower Normal challenge entails carrying a full on-hand lineup of level-50-plus Pokémon and defeating a gauntlet of NPCs en route to the top floor; losing to any one of them will effectively forfeit the reward payout, since you will respawn in a Pokémon Center and be precluded from rechallenging it until the cooldown time has elapsed (which is initiated as soon as you venture into the challenge). Once you reach the uppermost floor and speak to the prizewoman, you will be rewarded 5-15 of one type of the EV-reductive berries.
For a fee of 
2,000, you can do the Elite-mode challenge of the Berry Tower; this will reward EV-reductive berries contingent that you complete it—either 5 of each of the gamut of them or 25 of a particularized type of them, depending on what prizeset you select. The elite-mode challenge has a three-day cooldown, as opposed to the standardly one-day cooldown.
Headbutt Trees
Headbutting trees will have a chance of dropping berries.
Berry shops
Upon defeating the Pumpkin King boss in Vermilion City Graveyard, a berry-vendor will be made accessible in Goldenrod City Flower Shop. He will sell all EV-reductive berries for 3,000 apiece, thereby providing the most prolific avenue of obtaining them for those that are affluent enough to expend the requisite Pokédollars for them.
Extra-organic usages
All non-EV-reductive berries can be sold to the item-buyers that exist on the first floor of all Department Stores for 25 apiece, thereby providing a more marginal method of moneymaking for those that have plentifully collected berries.
