Leaf to turn over recently (2,4)
I believe the answer is:
of late
'recently' is the definition.
(synonyms)
'leaf to turn' is the wordplay.
'turn' indicates an anagram.
'leaf'+'to'='leafto'
'leafto' anagrammed gives 'OF LATE'.
'over' is the link.
(Other definitions for of late that I've seen before include "Alternative to 21 down" , "Recently, not long agor" , "recently, not long ago" , "In the past few days" , "Not long ago, in recent times" .)
