Dedicated, found in garden, toiling (6)
I believe the answer is:
ardent
'dedicated' is the definition.
(thesaurus)
'in garden toiling' is the wordplay.
'in' indicates a hidden word.
'ARDENT' can be found hidden inside 'garden toiling'.
'found' is the link.
(Other definitions for ardent that I've seen before include "Intensely devoted" , "'Fervent, impassioned (6)'" , "Passionate, fervent" , "Having great warmth of feeling like a lover" , "Enthusiastic, eager" .)
