Hello.
My front lawn is a mix of bermuda and fescue. I've been noticing
patches of
yellowing on the fescue grass throught my lawn. it seems to be
spreading (slowly but surely). the blades seem to be covered with a
yellow powder that comes off on your fingers if you touch it. it
looks like there are some small granuals on the blade as well. my
first thought was pollen, but it seems to only be affecting the fescue
grass.
I do have a young jacaranda tree that is shedding its small leaves,
but the yellow grass is in other parts of the lawn as well.
I don't recall this yellowing last winter. any thoughts?

thanks.
