Creeps pollarded growths around garden (5)
I believe the answer is:
edges
'creeps' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for edges that I've seen before include "Fringes" , "Outer limits" , "Margins" , "Slowly moves" , "They're used for cutting" .)
