Side disorganised away from home fails to survive (4,3)

I believe the answer is:

dies out

'fails to survive' is the definition.
(I've seen this before)

'side disorganised away from home' is the wordplay.
'disorganised' is an anagram indicator.
'away from home' becomes 'out' (synonyms).
'side' with letters rearranged gives 'dies'.
'dies'+'out'='DIES OUT'

(Another definition for dies out that I've seen is " fails to survive".)

I've seen this clue in The Irish News.
