New to Siberian Iris --advice?
So far, my only experience has been with bearded iris (a little).
I have a long ditch that feeds a permanent stream--the ditch always has some level of water in it. I was thinking I'd like to try the Siberian or Japanese iris in this location.
Are these hardy enough to take an occasional zone 5 type winter? (admittedly we don't go way below zero often but it has happened).
My soil is about a 6.8. Is this acid enough?
Where is the best location for the iris? (Top of the 3 ft+ bank in the dryer section, halfway down or almost in the water?)
Is there any special way to set them in the ground, any required amendments for my situation (silty loam)?
Thanks very much for advice. I'm looking at ordering from Siberian Iris Gardens in NY.
