I like to give each rhizome as much space as I can- 12" to 24" but it's never enough.
Water when dry two inches down. Every region has different requirements. Good luck - you're in good company here!

i cannot plant them that far apart in my current, tiny garden, and have to dig and divide every 1 - 2 yr., which can be back breaking work in the heat of summer and early fall.
here's some information to get you started, and as for planting iris, there are several videos on youtube.

Lestv said:Yes, always map your garden. In case the tags go missing or it blooms as the wrong iris, you have a source to check to see what that iris should be.
