Iris need at least a half day sun, so check that. they could be crowded or planted too deep. Need the top of the rhizome showing.

They are getting the sun and are not to deep as I replanted them last fall, and was very careful not to plant to deep.

In the south I plant where the rhizome is at least half out of the soil if not more. From what you said they are getting enough sun. How long is several years, Sundra? Are they growing with other plants that get fertilized? Many fertilizers that plants need are high in nitrogen. If irises receive a lot of nitrogen they will grow wonderful fans with little or no bloom. If you re-planted them last fall they may have taken this year to adjust and become established. Many irises do this and will bloom great the following year if the change has given them better growing conditions. You may have wonderful blooms next spring.

BTW, welcome to the irises forum!

Welcome! One other thing to consider is that they may not get enough chill during their winter. Some bearded irises need a cold spell before they bloom. I'm not sure of your climate there. Do you know what cultivar you have? Are they tall bearded, or the little ones?

can you post a few pictures of your trouble making irises? Could help in the diagnosis.

Not sure of the kind of iris they are as my grandfather planted them like 10 years ago. I will get some pictures of the today. Oh and they have been in this bed with no other plants tell this season when I just planted some Dianthus.

Welcome! Sundra ! It looks as if you have some fairly healthy plants, in a well maintained bed, with no weeds ,or grass for competition. I'm betting that next year will see a lot more bloom !
The others have all made some valid comments, so there is little I can add, but, to "restate": at least a half day's sun.....you say you have that. Planting depth "right'......in "heavy" soils (clay), the rhizome should be "partialy exposed', in "lighter" soils (sand), they can be planted an inch under the surface (but no more !), yours look to be about correct, as to depth. It's not unusual for iris to NOT bloom ,the first year after division, and replanting...especially in areas where they are "marginal" i.e. at the limits of their zone range, or, nutrient levels in the soil aren't quite 'correct" for iris (too much nitrogen, soil ph not quite correct, too wet (or too dry) growing conditions, etc. So, my thinking, if they were mine.....I'd expect bloom next year!
