Incorrectly and badly grown (5)
I believe the answer is:
wrong
'incorrectly' is the definition.
(I know that incorrectly can be written as wrong)
'badly grown' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'grown' anagrammed gives 'WRONG'.
'and' acts as a link.
(Other definitions for wrong that I've seen before include "Treat unjustly" , "Inappropriate" , "Unjust - incorrect" , "Inaccurate" , "Injury - incorrect" .)
