I'm closer than ever to completing the national dex in diamond (apart from the event Pokemon with you don't need) but I need a Milotic, and I can't seem to find Pamtre berries to make into poffins. I've been walking around in Amity Square for about half an hour with my pikachu and haven't picked up one berry.
>Diamond, Pearl, and Platinum
Found in Amity Square by a partner Pokémon.
Keep trying; picking up items in Amity Square is random.
And to be honest, while Pamtre Berry does have the highest Dry rating, Chesto or Charti Berries will do just fine; they'll make Poffins that increase the beauty condition as well.
