Gardener's tool (6)
I believe the answer is:
trowel
'gardener's tool' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for trowel that I've seen before include "Mortar-spreading tool" , "Scoop-shaped tool with short handle" , "Small hand tool for scooping" , "Small triangular tool for weeding in garden" , "This makes plaster spread" .)
