know they won't die without it, but perhaps it would be of some
benefit. Late in the season, around August, the iris gradually start
getting yellow or brown leaves. Is it better to cut them off? I don't
know if these leaves protect the rhizome, or maybe they are better
removed to prevent insects and rot from getting in.
My worst problem is 2 Siberians I bought this Spring. They grew about
8 inches, and that is it. They are in with the Tall Bearded. Perhaps
they take 2 years to get established. >>
Laetitia,
I would not recommend mulching any bearded Irises. It can lead to rot.
I would recommend removing the brown Iris leaves. Not only does it make the
plants more attractive, it also reduces the risk of an infestation by the
Iris Borer.
Siberians should be easy to grow in your area. They did fine for me
when I used to live in Kentucky. Siberians usually like conditions more
acidic than the bearded Irises. Most people grow them in separate Iris
beds. Sometimes, they can be a little slow to establish.
