Type of green turf needs cutting
I believe the answer is:
pea
'type of green' is the definition.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for pea that I've seen before include "Edible green seed" , "Common vegetable seed from pod" , "veg" , "Leguminous plant" , "12 in a pod" .)
