irises

I don't know about when, maybe in the spring would be better. But I do know that you don't really bury the bulb deep at all, almost like having it just covered with dirt. I learned this from a friend who got irritated with me because I wanted to really bury the bulb like other plants..lol

Are you close to getting snow? If you have about a month before snow/frost will hit, you can still plant them. I found this site that might be helpful... http://www.beautiful-view-iris.com/planting.html Hope this helps. :)

Well without more information I can only give the following advice on Irises. You'll need to plant them in the spring, mid or late April or later and it'll be fine. Depending on the type of iris you'll need different planting conditions. For example, bearded irises (common, probably what you got) need less moisture or a dryer site and will bloom earlier so you can watch for that. Siberian irises need much more moisture. The best news for you though is that Irises are rather hearty plants and they can even survive general neglect. They'll grow in any zone at 3 or higher too.
