Olearia Hedge

QuestionsOlearia Hedge
Paul Byrne Staff asked 16 years ago

I planted 140 Olearia plants in early 2006 as a wind break along 35 metres of my garden which runs to the sea. They had flourished until this month. I notice that approx 30/40 are dead or dying in intermittent clumps along the garden. There has not been any spraying near the hedge. I dug one up but did not notice any pests in the root ball.Why would this be?
