Orange tree leaf fall

[Dan[_9_]]

Hi all,
My Washington Navel Orange tree has started shedding its leaves. Leaves have
turned yellowish and are carpeting the ground under the tree. I have five
other citrus trees including another orange and they seem to be unaffected.
I live on the Atherton Tablelands in a subtropical climate. Though the area
sometimes gets frost I am too high on the side of a hill to get frost except
in extreme conditions, and there has been no frosts this season so far.
Does anyone have any idea what may be the cause and, if so, what I can do
about it.
Thanks,
Dan

Did you just fertilise the tree? Has it been very wet lately?

Hi David,
No to both. I generally fertilize when crop is finished - around September.
We had a fairly wet summer, but have had dry weather for some weeks. Another
citrus is almost touching this one and it is unaffected. A bit of a puzzler.
Cheers,
Dan

sounds like what happened to my mandarin - didn't figure it out and
couldn't save the tree. Good luck
