I don't have time to read all the stuff on irises so hoping someone (or several) can answer my questions. I live in zone 5 Colorado. Cold, snowy winters and hot, dry summers (although not this year).
I have many iris, 2-3 years old. They are planted in several small "plots", only one of which gets a good amount of sun, the other 2 areas are in partial shade. When they bloom, I only get a few blooms and some have never bloomed. The foliage is outstanding and appears quite healthy.
Is the lack of bloom being caused by (1) being planted too close together, (2) being planted too deeply, (3) too little sun, (4) other factors? I have
Also, I have been given several healthy rhizomes early this week (4th week of July). I do not have time to plant them now. How can I store them and how long can they be stored? I would like to relocate all the iris to a dedicated iris bed. What is the best time to transplant?
