'sweet way to' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'tree fall over' is the wordplay.
'tree' becomes 'gum tree' (gum is a kind of tree).
'fall over' becomes 'drop' (synonyms. I am not sure about the 'over' bit.).
'gum'+'drop'='GUM-DROP'

'see' acts as a link.
