Why is my Lilly Pilly tree declining in health?

[murrayjohn]

Hi Garden discussion

I am trying to figure out why my lilly pillys are not looking well  i live  geelong victoria they were planted 5 years ago always been looked after trimmed, and sea soled sprayed twice a year nice and health

Now in the last 6 months the have declined rapidly i have read all you articles on care and pests etc some one suggested the look like a lack of water but get watered when dry maybe to much every thing is growing around the area

have inspected the leaves closely and found no pests the branches at the top are britle snap easily have always trimmed to a manageable height  6-7 ft

should i give them a really good cut back a dose of eco oil as some suggestion have been written

 i don`t want to lose them as i love my gardening  i will up load some images

thanking you

Thank you @Noelle

i thought that might be the case should i hand trim all the deadwood up top which means i probably have to trim 100mm off top or should i wait till it get  a bit cooler down here in vic

Wait until it's a bit cooler - around mid March.
