Settling in? They were all happy in their pot,so they bloomed, now they have more room to grow roots, so they're working on that for a while. I take care of gardens, and I've noticced that most of the blooms on Siberians are toward themiddle of the clump, where they are more crowded.

Are they in the ground or in a pot?

They bloom sparsely in shade, much better in sun.

Mine didn't bloom this year either. Wonder if it was the weather?

I found the secret to the iris blooming.Pull the mulch away from the base of iris.Pull it back all around the plant and like to be crowded.It will bloom imediately.Mine are done blooming here.

Well, neither the ones in the sun nor the ones in the shade are blooming. There's no mulch around them. So right now, it sounds like the settling in or the weather hypotheses are fitting best. But they did bloom last year. Hmmm ...

The main problem for not blooming is too much mulch or soil on roots,Alot of roots are sticking out of ground o0n mine.pull some soil away see if they bloom.I did and within 2 days buds were up.
