Hello Alan,
Nitrogen is the biggest problem.  If you use 5-10-10 or 5-10-5 or even 
10-10-10 in small amounts, you should not have any problems.  Nitrogen 
is to iris like salt is to humans, causes increased water retention and 
size increase, which for iris will cause ROT, that awful smelly 
fragrance in the garden.  This is for bearded iris only. Beardless iris 
are heavy feeders and need plenty of the big 3. If you are shipped any 
rhizomes that are huge like potatoes, hang them upside down outside for 
at least a week, and watch the water drip out!!!
How is MA this time of year, and how was your bloom season.
