Do away with uncultivated vegetation (5)
I believe the answer is:
scrub
This clue might be a double definition.
'do away with' is the first definition.
(I've seen this before)
'uncultivated vegetation' is the second definition.
'scrub' can be an answer for 'vegetation' (scrub is a kind of vegetation). I am not sure about the 'uncultivated' bit.
Can you help me to learn more?
(Other definitions for scrub that I've seen before include "remove cosmetic" , "Curbs (anag.)" , "Clean, low vegetation" , "Abandon" , "plants" .)
