Re: RE: Deep planting

I am glad that worked for you.  I can't say deeper planting helps my 
survival rate
at all.  Of the new TB's that I received third week in August that year 
and which
I had planted that way only 50% survived.  A bigger factor in the 
survival rate for
me is when I plant them.  I rarely lose any irises if I plant them in July.
