Pokemon don't evolve through level up in the anime. In the anime, evolution generally happens during a crucial moment, such as when the Pokemon is in trouble. It's also possible that Bulbasaur was well liked by the fans and they didn't want to see him evolve.
Bulbasaur does not evolve during the Pokemon anime series, there is an episode where Bulbasaur is about to evolve, but he restrains himself from doing so, because it didn't wish to evolve
Bulbasaur does not evolve with a stone. Bulbasaur needs to get to a certain level, then go to "Luminous spring", select Bulbasaur, then select "evolve". If YOU are Bulbasaur, then you must get Manaphy and Palkia to join your team, and then go to "Luminous spring".
bulbasaur should evolve into a ivysaur at level 16 and then you can evolve it into a venusaur at level 32 you can find out more about bulbasaur if you go onto this link here http://pokemon.wikia.com/wiki/Bulbasaur !!
well ash's squirtle will never evolve because of the squirtle squad and his bulbasaur chooses not to evolve, in episode 51 bulbasaur was going to evolve along with a large group of other bulbasaur but it chose not to, so it never will.
No...... Ditto can never evolve.
Bulbasaur has to be level 16 to evolve into Ivysaur and level 32 to evolve into Venusaur.
