Shoot for almost the whole season (5)
I believe the answer is:
sprig
'shoot' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sprig that I've seen before include "Small nail without a head" , "Young person" , "Stem of holly, for example" , "Small leafy stem" , "Youth" .)
