I have a customer whose hedge is dying back and need some help please.
It is a Griselinia littoralis and is approx. 60m long with a dog leg. Probalb yabout 20 years old??
It started dying back, leaves, branches, stems everything; about 3 years ago and is slowly spreading to the whole hedge.
What could be the reason and would it be ok to replant similar in same position.
The garden is on the edge of a quiet road, 1 mile or so from the sea.
