The Garden of Eden is said to be where God created the first humans, Adam and Eve, and they lived there until the “Fall.” During the time of the Fall, God cast Adam and Eve out of Eden for eating the fruit from the Tree of Knowledge, which they had originally been forbidden to do.
The Garden of Eden is linked to the secret garden when Martha tells Mary the story of Mistress Craven and the garden’s history. Martha tells Mary of the lovely and peaceful times that Master and Mistress Craven spent within the garden together. These divine times came to an end with the literal “fall” of Mistress Craven, or when she fell out of a tree and to her death in the garden. After this fall, Master Craven banished himself from the garden and locked it up, so that no one could enter, as Mistress Craven’s death had tainted the beauty and sanctity of the garden. This parallels how Adam and Eve’s (less literal, more figurative) Fall caused them to be banished from the Garden of Eden by God.
Later on, Mary and Dickon reenter the garden together. For them, the garden represents a paradise of beauty and innocence, much like the Garden of Eden and the secret garden originally did for the Master and Mistress Craven. In the garden, the children develop and experience an exceptionally intimate relationship with God. They work to rejuvenate the garden together and seem to become “Adam and Eve,” returning to the garden to right what had been wrong there. The motif of the Garden of Eden adds another dimension to The Secret Garden, and allows the audience another perspective on and another window into the events that take place in the story and, more specifically, in the secret garden itself.
