Applied manure to garden and drive, and scattered seeds (7)
I believe the answer is:
dressed
'applied manure to garden' is the definition.
(I've seen this before)
'drive and scattered seeds' is the wordplay.
'drive' becomes 'dr' (abbreviation used in road names).
'and' means one lot of letters go next to another.
'scattered' indicates anagramming the letters.
'seeds' is an anagram of 'essed'.
'dr'+'essed'='DRESSED'
'and' acts as a link.
(Other definitions for dressed that I've seen before include "Applied manure to garden" , "Attired" , "Clad" , "with mayonnaise, say" , "in fancy packaging" .)
