The olearia hedge which we planted 15 years doesn’t appear to be growing any new leaves this spring. It was cut back in the autumn but new grow is virtually non existent. The leaves are dead and shoots appear woodly and dead. Is there any way to revive it and bring it back. It is our boundary hedge which is totally exposed to harsh conditions as it faces directly onto south beach. I fear our early harsh winter has done a lot of damage. How can we tell if there is still life in the roots or what treatment do you advise to try and revive it.
If should have sprouted by now. Scrape away some bark at soil level and it is brown underneath, it is dead.
