Budew evolves into Roselia with:
Max Friendship
DayTime
and then when you get these requirements, just level up!
Then poof! You'll now have a Roselia, Roselia evolves into Roserade with a Shiny Stone
Budew, whether playing Diamond, Pearl or Platinum will only evolve if you have a strong friendship with it. Once you have a close bond with Budew, you must level it up during the daytime for it to evolve into Roserade.

There is no specific level that a Budew will evolve at. However, if you level it up on high happiness, you will end up with a Roselia. And if you use a Shiny Stone on the Roselia, you will get a Roserade.

You'll need to make it have high happiness/friendship during the day to make it evolve into Roselia.
