There are many reasons why your iris may not bloom.

Not all will bloom the following summer from planting.

Read the FAQ.

No need to use bonemeal, that's pretty old fashioned although some would like it becuase it is "natural."

Many irises take a year to get established. They need lots of sun, and the top of the rhizome should be above soil level. They don't need to be fertilized much- I never fertilize mine. If you decide to fertilize, wait until early next spring and use a low nitrogen product.

Good luck!

As Renee said it is quite normal for beardeds to take a year, even 2 sometimes, to settle in.

To know if your soil is deficient in phosphorus and potash, both of which rhizomes, you would have to do a soil test.

If you dislike bonemeal, superphosphate is another source or phosphorus. Don't know its base.

You can burn chicken/fish bones to supply nutrients more quickly. This type of raw compost used as is would take forever to break down and animals may root it up.
