hello, I have had some problems in the iris that I planted in the ground, in some varieties,
the mother rhizome dry (shrivel) very quickly, in less than a year after planted, leaving only the children; the same with those I have in pots.Here in Portugal southern Europe we have a
hot and dry summer much like that of California.
In summer I water them every week and cover the top exposed surface of the rhizomes with a thin layer of soil.
They catch the sun all day.
Should I plant them where they catch a few hours of shade?
Should I plant them deeper?
Does someone can help me?
Thank you
HELDER
