I'm a little stuck... Click here to teach me more about this clue!

'what nurseries' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'ask for looking after them?' is the wordplay.
I cannot really understand how this works, but
'ask for' could be 'charge' (I've seen this before) and 'charge' is located in the answer.
The remaining letters 'smalls' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'may' acts as a link.
