Girl initially put out by date refreshing Instagram to reveal trees (9)
I believe the answer is:
tamarinds
'trees' is the definition.
(tamarind is a kind of tree)
'girl initially put out by date refreshing instagram' is the wordplay.
I cannot really see how this works, but
'girl' could be 'tamar' and 'tamar' is located in the answer.
'date' could be 'd' (common abbreviation eg in DOB, date of birth) and 'd' is found within the answer.
The remaining letters 'ins' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'to reveal' is the link.
(Another definition for tamarinds that I've seen is " trees".)
