Edna didn't die in any specific episode. The Simpsons were oddly indirect about addressing Marcia Wallace's & therefore Edna's death until Season 25's The Man Who Grew Too Much. They were a little more direct when they showed Ned wearing a black armband with a photo of Edna (& Maude) saying to Nelson, "I sure do miss her laugh".It was in later seasons that they finally showed Edna has a ghost.
