Re: Iris orders, root pruning et al
I would like to see the 20 varieties Shreiners 'pulled'.
One of our club members, Dr. Bill Greise of Kentucky (Louisville?) wrote an
article a while back about root pruning. I think it was in the AIS bulletin.
He did some experimental comparisons where he root pruned some and not
others and then dug them up over the following growing season (summer fall)
to look at what they were doing below ground. He saw a benefit to the plant
from leaving the roots as intact as possible. At least that's my fuzzy
memory of what he said. I will try to find the article or ask him next time
