Kali,

>From the information above it is difficult to determine why your iris
are growing so poorly.  The high nitrogen fertilizer could be a factor,
but you failed to mention how you used it.  It is generally accepted
that a low nitrogen fertilizer is best for iris.  Too much nitrogen will
promote lush growth at the expense of flowers and perhaps burn the
foilage.  Use a fertilizer with the first number under 10.  Something
like 6-20-20 or 5-10-5 would be better. 

I would be interested in hearing how you prepared your new bed in order
to come to any conclusion!
