I can't get my iris plants to bloom. They were planted last year. What could be wrong?

They aren't planted very deep. I have one that has grown alot, but no blooms. Can anyone help? Thanks, Candice

most of the time it can take at least 2-3 years after you plant them for them to bloom. be patient it will be worth the wait to see the beautiful flowers next year.
Reply:Maybe not enough sun or water. Some plants take two years or more to bloom.
Reply:If you have bearded iris and have the bulb part fully underground they likely aren't blooming because they are too deep. Bearded iris like to have at least the top half of the fleshy bulb (called a rhizome) above the ground.



If this is the problem dig them up and replant so that the top of the rhizome is above ground but the roots are buried. You probably won't get blooms this year unless they are a late or rebloomer.



Sometimes iris don't bloom because they aren't strong enough, and will wait a year to build the reserves needed to flower. It can also be that they need more time to settle, but at a year I'd think it would be planting depth more than anything. Another cause could be they are really late bloomers, and won't bloom until the end of what is considered iris season.
Reply:I planted 3 rhizomes each of 2 different irises 2 autumns ago. The one iris bloomed the following spring, but only on one of the rhizomes. The other one grew alot of leaves but no blooms. This year, the iris that did bloom last year has flower stalks on all the rhizomes and is blooming beautifully. The other one has buds on it but looks like it is being hit with Iris borer. I had to cut the biggest flower stalk off because it had streaks of flesh exposed and the rest of the flower stalks don't look very good. It looks like this particular variety is very susceptible to Iris Borer. I will have to dig them up and burn them. You don't want to compost foliage that is suspected of having borers.
