Wondering about leaf streak as well. After a recent hard freeze,
the foliage began to show what looks like leaf streak on the outer
leaves, but maybe it is just freeze damage.
Hubby pulled off the affected leaves very early this morning. That was
my pleasant surprise when I got up. Yeah, he's a keeper.
Leaf streak is the one thing I totally dislike. We have researched it, but
haven't found any organic way to tame the beast, except to pull off the
affected leaves and remove leaf debris late winter before the daylilies begin to grow.
Some say to remove leaf debris in the fall, and we do when adding new mulch, but once the freezing temps begin, there will be plenty of dead leaves to remove no matter what.
I really hate to use fungicides, but may have to resort to that if leaf
streak is noted in a big way, and I'm not as yet certain that fungicides really
help all that much. Hope others have ideas.
