Field of fruit — beginning to be harvested (5)
I believe the answer is:
range
'field' is the definition.
(I've seen this in other clues)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for range that I've seen before include "Cooking appliance" , "Limit of effectiveness" , "Old-style cooking stove" , "Scope; ambit" , "Cut; cultivated plant" .)
