How deep do you have those iris planted? I don't see the rhizome. The top of the rhizome should be above ground so that it can get sunlight. If not they don't bloom, or bloom very little.

In zone 4 I would think it is still too early for stalks to appear yet. I could be wrong.

You can't see in that pic, but the tops of the rhizomes are exposed. Maybe you are right and it's just too early for stalks. I saw all these posts about blooms and just assumed I was foiled again this year! I can't recall the phenology of when iris bloom here.

I think it might be too early yet. I still have a number of irises that have not bloomed, and I'm in California.

Good news.... I have about 6 buds waiting to blossom into flowers!!! I was just too impatient. ;-) Will post pics when they bloom!!

That's great! I have one clump of no shows, can't remember what they are.

I learned the hard way, and most transplants I lose a season of bloom. Some other ones even if I don't get them planted exactly right, they eventually do their own thing and bloom.

I think it helped some to bloom faster once I read on this forum to leave some rhizome exposed and trim. But one huge bunch I planted too deep took 3 years to bloom and now they are too many for where they are, blooming like crazy.

Can't wait to see!
