Rented garden plot (9)
I believe the answer is:
allotment
'rented garden plot' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for allotment that I've seen before include "allocation" , "Vegetable plot" , "cultivated area" , "Small rented gardening plot" , "Share - small piece of land rented for cultivation" .)
