I have a coastal live oak tree in my backyard, that until
recently has been in great health.
However, today I noticed some brown spots on
the leaves - in fact, this is quite widespread.
I posted a photo at:
Nothing very special happened to the tree recently.
Below it there is some dry leaves-covered ground,
and (not adjacent to the trunk) a lawn that is
also somewhat dry.
Recently, the gardeners put a small amount of
fertilizer on that lawn, but that had been done
before without ill effect.
Any idea of what this is?
