Roserade cannot learn Razor Leaf through leveling up. However, Budew, Roselia, and Roserade can learn Razor Leaf through breeding.
In order for one of the three Pokemon to know Razor Leaf, you need to breed a female Budew, Roselia, or Roserade with a male Bulbasaur, Ivysaur, Venusaur, Bellsprout, Weepinbel, Victreebel, Chikorita, Bayleef, Meganium, Sunkern, Sunflora, Nuzleaf, Shiftry, Tropius, Turtwig, Grotle, Torterra, Cherubi, Cherim, Snover, Abomasnow, Cottonee, or Whimsicott.
Please note that the Pokemon listed above in bold are able to learn Razor Leaf, and may require them to know Razor Leaf to breed with Budew, Roselia, or Roserade for a Budew that knows Razor Leaf.
