grass types
Grass Pokemon are weak against Fire, Ice, psychic, Poison, Flying, and Bug type moves. The effectiveness of these types of attacks may be increased or decreased if the Pokemon has two types. For example, Bulbasaur is a dual Grass / Poison, so Poison attacks are not as effective.
Water type moves and Grass type moves. Electric moves will have no effect. Flying types and Pokemon with levitate ability are good as ground-type moves have no effect against them.
Rock-type Pokemon are weak against Water, Grass, Ground, Steel, and Fighting-type attacks, which doubles the damage received from one of these types.
The types that are good against the ground type are water, grass, and ice types. Water and Ice types are usually profoundly effective, as the ground type is often paired with the rock type.
