plumbed

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

'got to the depth of' is the definition.
I can't judge whether this definition defines the answer.

'fruit plot' is the wordplay.
'fruit' becomes 'plum' (plum is a kind of fruit).
'plot' becomes 'bed' (a plot of land).
'plum'+'bed'='PLUMBED'

'the' is the link.
