Trim wood (6)

Ross

I believe the answer is:

I believe this is a double definition.

'trim' is the first definition.
(synonyms)

'wood' is the second definition.
(spruce is a kind of wood)

(Other definitions for spruce that I've seen before include "tree with needle-like leaves", "Neat and trim like fir tree", "Coniferous tree", "wood", "Neat and tidy like tree".)

I've seen this clue in The Times.
