Bed of roses with trees, as yet to be replanted (4,6)
I believe the answer is:
easy street
'bed of roses' is the definition.
(thesaurus)
'trees as yet to be replanted' is the wordplay.
'to be replanted' indicates anagramming the letters (letters get placed or planted in new positions).
'trees'+'as'+'yet'='treesasyet'
'treesasyet' with letters rearranged gives 'EASY STREET'.
'with' is the link.
(Other definitions for easy street that I've seen before include "one appreciated by deliveryman?" , "Financial security -- teeters, say (anag)" , "enjoyed by a roundsman?" , "A bed of roses" , "the life of Riley" .)
