wintertime

'december?' is the definition.
(December is part of winter)

'women put in ground with draw to' is the wordplay.
'women' becomes 'w' (standard abbreviation).
'put in ground' becomes 'inter' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'draw to' becomes 'time' (I am not sure about this - if you are sure you should believe this answer much more).
'w'+'inter'+'time'='WINTERTIME'

'entice mass in' acts as a 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 wintertime that I've seen before include "when cold" , "Season" .)
