Cleaning up the garden bed for a little party (7)

I believe the answer is:

weeding

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

'cleaning up the garden bed' is the definition.
I can't tell whether this definition defines the answer.

'little party' is the wordplay.
'little' becomes 'wee' (similar in meaning).
'party' becomes 'ding' (I can't justify this - if you can you should believe this answer much more).
'wee'+'ding'='WEEDING'

'for a' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
