Tree maintenance check (7)

Ross

I believe the answer is:

service

I believe this clue is a double definition.

'tree' is the first definition.
(service tree is a kind of tree)

'maintenance check' is the second definition.
(eg a boiler service)

(Other definitions for service that I've seen before include "Work done by one for the benefit of another" , "Waiting" , "See 4" , "Act of worship" , "Tennis opening shot" .)

I've seen this clue in The Telegraph.
