Go for replanted forest where domestic growth high?
I believe the answer is:
roof garden
'where domestic growth high?' is the definition.
(I've seen this before)
'go for replanted forest' is the wordplay.
'replanted' indicates an anagram (letters get placed or planted in new positions).
'forest' becomes 'arden' (I've seen this before).
'go'+'for'='gofor'
'gofor' anagrammed gives 'roofg'.
'roofg'+'arden'='ROOF-GARDEN'
(Other definitions for roof garden that I've seen before include "where domestic growth is highest" , "where domestic growth high?" , "High-level greenery" , "Elevated area of greenery" , "that's grown at highest level" .)
