Ridiculous tripe about Victor making hedge (6)
I believe the answer is:
privet
'hedge' is the definition.
(I've seen this before)
'ridiculous tripe about victor' is the wordplay.
'ridiculous' indicates an anagram.
'about' indicates putting letters inside.
'victor' becomes 'v' (phonetic alphabet: alpha, bravo, charlie etc.).
'tripe' anagrammed gives 'priet'.
'priet' placed around 'v' is 'PRIVET'.
'making' is the link.
(Other definitions for privet that I've seen before include "Bushy evergreen shrub used for hedges" , "hedge material" , "Half evergreen European shrub of the olive family" , "Shrub much used for hedges" , "Let the vet rip up the hedge" .)
