Tidy jasmine at entrance, clipping what's choking it (6)
I believe the answer is:
neaten
'tidy' is the definition.
(I know that tidy can be written as neaten)
'jasmine at entrance clipping what's choking it' is the wordplay.
'clipping what's choking it' indicates a hidden word (remove the letters that are smothering the answer).
'NEATEN' is hidden in the letters of 'jasmine at entrance'.
(Other definitions for neaten that I've seen before include "Trim" , "Groom" , "Spruce up" , "Straighten up" , "set in order" .)
