Greens convert Pip to cycling (6,3)

I believe the answer is:

turnip top

I'm a little stuck... Click here to teach me more about this clue!

'greens' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'convert pip to cycling' is the wordplay.
'convert' becomes 'turn' (synonyms).
'cycling' indicates an anagram.
'pip'+'to'='pipto'
'pipto' with letters rearranged gives 'iptop'.
'turn'+'iptop'='TURNIP TOP'

Can you help me to learn more?

(Other definitions for turnip top that I've seen before include "vegetable?" , "Following two years of growth" .)
