Digs the peaty soil up (4)
I believe the answer is:
room
'digs' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for room that I've seen before include "Chamber; scope" , "Enclosed space in a building" , "Space; chamber" , "Place" , "Box ---, storage area" .)
