Husband - creep that's often at the bottom of the garden (5)
I believe the answer is:
hedge
'often at the bottom of the garden' is the definition.
I can't judge whether this defines the answer.
'husband creep' is the wordplay.
'husband' becomes 'h'.
'creep' becomes 'edge' (I've seen this in other clues).
'h'+'edge'='HEDGE'
'that's' is the link.
(Other definitions for hedge that I've seen before include "Financial contract" , "Bushy barrier" , "Try to avoid answering questions or dealing with issues" , "Barrier of shrubs etc" , "avoid making commitments" .)
