Blew pot with nerves trembling (9)
I believe the answer is:
overspent
'blew' is the definition.
(overspending is a kind of blowing)
'pot with nerves trembling' is the wordplay.
'with' says to put letters next to each other.
'trembling' is an anagram indicator.
'pot'+'nerves'='potnerves'
'potnerves' anagrammed gives 'OVERSPENT'.
(Other definitions for overspent that I've seen before include "Beyond budget" , "financial crisis" , "Used too much money" , "broke" , "Invested too much" .)
