Need to rearrange the garden (4)
I believe the answer is:
eden
'garden' is the definition.
(Garden of Eden in the Bible)
'need to rearrange' is the wordplay.
'to rearrange' indicates an anagram (I've seen 'rearranged' mean this).
'need' is an anagram of 'EDEN'.
'the' is the link.
(Other definitions for eden that I've seen before include "Place of unspoiled beauty" , "Genesis location" , "The most enchanting garden of all" , "Adam and Eve home" , "heavenly spot" .)
