Embellished his garden differently (9)
I believe the answer is:
garnished
'embellished' is the definition.
(garnishing is a kind of embellishing)
'his garden differently' is the wordplay.
'differently' indicates anagramming the letters.
'his'+'garden'='hisgarden'
'hisgarden' is an anagram of 'GARNISHED'.
(Other definitions for garnished that I've seen before include "Added parsley, perhaps" , "Decorated" .)
