pf275:

We here in Ferns are disappointed you did not post this in Ferns. Especially as you posted this in Roses.

Are we somehow less deserving than Roses?

Please post this in Ferns.

Perennialfan, I'm in your zone, and our climates are similar. My irises are not blooming yet, either. But, since yours were planted a few years ago, and healthy but not blooming, I suspect besides being planted too deeply, they have multiplied and need digging up and dividing. Cut the newer rhizomes off and toss the old, original rhizomes, then replant the newer ones with the tops showing. If the clumps have multiplied and gotten too crowded, they won't bloom. Now, you have enough to plant in other places and share with friends. Most importantly, as gardengal said, they want to be planted close to the surface with the tops of the rhizomes showing. This is for bearded iris - I don't know about the other types.

@gardengal and flowers thank you for your advice. As far as the whole "planting too deep" thing is concerned, does this apply to other iris species as well or only bearded iris? As I said I can't remember exactly what species this is so sorry I can't be more specific about that.

Only the beardeds produce that big, fleshy rhizome that needs sun exposure. All the rest can be planted normally.

Posting this thank you. I planted some gifted Iris last year with no idea what they were planting them rather shallowly. One bloomed fantastically and it is a bearded iris. I think my stachus lunetta is covering the other ones and preventing them from blooming. Also the mulch in another bed. I'm going to pull it back and see if that helps. Would it help this year or would I have to wait till next year? Please excuse misspelling on voice recognition I cannot type with who's on my phone.

You need to dig them up and reset them at soil level. And not too close together either. Irises will stop blooming if the rhizomes are too crowded together or planted too deep. I dig a shallow trench and lay the rhizomes in and only cover them about halfway up the sides when I split mine.

I plant the same as Seil and have pretty good luck. Mine were'nt blooming a few years ago and a neighbor said you plant them like you see a duck on the water, about halfway deep.
