When does Roselia evolve into roserade on Pokemon diamond?

Answer 1

To evolve a Roselia into a Roserade you must use a shiny stone on it. It won't work if you make a Roselia hold it. Just select use and then use it against Roselia. It'll evolve into a Roserade. Roserades have a high amount of Special Attacks so use Tms on it that teach special moves. Here's a list of them. Shadow Ball, Sludge Bomb, Energy Ball, Extrasensory, and Attract. The last one will help out because Extrasensory isn't that good with Roserade.

you need to find a Roselia you can get 1 in the tropey garden, you can run into: pichu, pikachu,krickitoon maby other Pokemon. well you have to use a shiney stone on it it'll become a roserade
