Tree looks rather healthy apart from black tips and blackened edges. Some leaves have turned completely black and fallen off the tree.

Some of the roots appear to be black and brown seems to be dead roots.

Answer:
Hi Marty, Remember Dale in ‘The Castle’…he dug a hole…pure genius! You need to do the same around the plant/s; look for really dry soil or a swamp. If dry (as Dale & I suspect), get some Everydrop from Bunnings and apply it as per instructions on the container. Be sure to treat a large area about 4m in diameter around each tree. Then put a sprinkler in it for at least an hour. Lastly, get some Yates Anti Rot to help the roots recover. If it is a swamp, move the plant next winter. Don
