Good-for-nothing fruit farm (6)
I believe the answer is:
grange
'fruit farm' is the definition.
(thesaurus)
'good-for-nothing' is the wordplay.
'good' becomes 'g' (abbreviation).
'for-nothing' becomes 'range' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'g'+'range'='GRANGE'
Can you help me to learn more?
(Other definitions for grange that I've seen before include "Country house/farm" , "US lodge" , "Farmhouse" , "Country-house" , "farming complex" .)
