Avoid commitment to a boundary (5)

I believe the answer is:

hedge

I believe this is a double definition.

'avoid commitment' is the first definition.
(I've seen this before)

'to a boundary' is the second definition.
(I've seen this before)

(Other definitions for hedge that I've seen before include "bush as a > barrier" , "Bushy barrier" , "Be shifty" , "Stall" , "Fence formed by bushes" .)

I've seen this clue in The Daily Express.
