Try hard to fix legs holding gardener's basket (8)
I believe the answer is:
struggle
'try hard' is the definition.
'fix legs holding gardener's basket' is the wordplay.
'fix' indicates anagramming the letters.
'holding' is an insertion indicator.
'gardener's basket' becomes 'trug' (type of basket used for carrying flowers).
'legs' with letters rearranged gives 'sgle'.
'sgle' enclosing 'trug' is 'STRUGGLE'.
'to' acts as a link.
(Other definitions for struggle that I've seen before include "Try hard to get free - labour" , "Strenuous effort against opposition" , "Make strenuous efforts to overcome" , "Tussle" , "Make one's way with great difficulty" .)
