Something to do after sowing (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
reap
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for reap that I've seen before include "Cut the corn" , "Harvest (a crop)" , "Derive as advantage" , "Get -- derive" , "Cut and gather (crop)" .)
