The odd wild yeast in time for mid-March (4)
I believe the answer is:
ides
'for mid-march' is the definition.
(I've seen this in another clue)
'the odd wild yeast' is the wordplay.
'the odd' indicates alternate letters.
'wild'+'yeast'='wildyeast'
The alternating letters of 'wildyeast' are 'IDES'.
'in time' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ides that I've seen before include "March 15; dies (anag.)" , "Period in month" , "Caesar's fateful day" , "Julius Caesar's unlucky day in March" , "Caesar was warned to beware the ones of March" .)
