Gardening equipment, if lost, would be more concerning (9)
I believe the answer is:
scarifier
'lost would be more concerning' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'gardening equipment if' is the wordplay.
I cannot quite understand how this works, but
'if' is found in the answer.
The remaining letters 'scarier' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for scarifier that I've seen is " Tool for lawn care".)
