Hi
Many thanks for your response.
I will see what the water does around the tree as you suggest.
The treee does get some automatic spray from the irrigation system that waters around 05.00am.
The tree seems have got worse recently since it became quite windy and hot. I was wondering if it could be wind burn? Are these trees open to this?
I will get hold of a PH testing kit as you suggest and the fungicide spray etc
What PH should the soil be?
Thanks again
