Having recently retired and being quite
interested in gardening, I would like to learn more about growing irises.
My interest in irises began about 25 years ago when a dear friend gave me starts
of his beautiful hybrid irises. I now have many; but in recent years they
have developed a number of ailments that I do not know how to effectively
control. Last spring when they began growing, I noticed a substantial
number of slugs chewing on the leaves. The leaves became striped with
brown and many eventually died. I tried spraying Sevin and removing the
dead or dying leaves. Also tried a fungicide but this may not have been
timely. The blooms were fewer than normal. This fall I cleaned out
all of the dead foliage and soaked the ground with a spray of Sevin and
Any good ideas regarding control of iris insects
and diseases would be helpful. What I have been doing has not been
adequate to date.
