Go by front of orchard to get fruit (4)

'fruit' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?

'go by front of orchard' is the wordplay.
'go' becomes 'pep' (both can mean energy or vitality).
'by' is a charade indicator (letters next to each other).
'front of' indicates taking the first letters (the letter at the front of the word).
The first letter of 'orchard' is 'o'.
'pep'+'o'='PEPO'

'to get' acts as a link.
