Landscaper's supply (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
sod
'landscaper's supply' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sod that I've seen before include "Lump of turf or unpleasant person" , "Piece of grassy soil" , "Surface layer of ground with grass roots" , "Lump of earth" , "A piece of sward." .)
