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.
