You can find berries on Pokemon Diamond is that you can plant them.For free berries,you can find them in Route 211,in a house above where a man was,a girl in Pastoria City,and a girl in Floaroma in the Floaroma shop.
No, you can't buy berries in Pokémon Diamond.
they r not in this game
Bidoof usually holds berries, the are always oran berries in Platinum, so it should be the same in Pokemon Diamond and Pearl. Hope this helped:)
You can find Pamtre berries in Amity Square in Hearthome City
by using the sprayduck or waiting
mostly berries but it could be something else.
the best ones are the chesto, oran, wiki, razz, pamtre, and ganlon. that is all i know at the moment. ill update when i find out more.
To get maximum beauty you have to feed the Pokemon either lv.20+ poffins made from wiki berries, or poffins made from pamtre berries. If you're trying to evolve feebas - which I'm guessing you are - you don't have to completely maximize it but get very close. Pamtre berries can only be found by strolling around in Amity square (with any Pokemon), and even so they are rare.
Pecha berries should be sweet.
I have all of them and nothing happens
Pick them off plants in the soil.
