Neil maybe it is because I plant way too
close , have no air circulation. Or that I compost all my iris leaves including
ones with leaf spot. I did not spray for leaf spot this year because it has been
dry. I did have a little later this fall. I have been known to use 12-12-12 when
that is all I have.
Some might not grow great but it doesn't
kill hardly any. Squirrels kill more than I do.
I dug about 90% of them this year
and growth is not looking great now, maybe if it cools off.
Planted with a Power Shoehorn
Most are two year
clumps. One to 4 rhizomes planted per clump.
