Sprinkle garden plot before we return (5)
I believe the answer is:
bedew
'sprinkle' is the definition.
(thesaurus)
'garden plot before we return' is the wordplay.
'garden plot' becomes 'bed' (I've seen this before).
'before' means one lot of letters go next to another.
'return' shows that the letters should be reversed in order.
'we' reversed gives 'ew'.
'bed'+'ew'='BEDEW'
(Other definitions for bedew that I've seen before include "Moisten (poetic)" , "Sprinkle with water (poetic)" .)
