Why are some of my newly-planted iris not blooming this spring?

Question

I received some iris starts from a friend last fall. This spring, only six of the ten plants have blossoms. Do you have an idea why the rest haven't bloomed?

Answer 1

 

Probably your iris just need another year to establish themselves. It is common for only about three-fourths of a new planting of iris to bloom the first year, so you are about on target. Just give them another year and a little fertilizer of bone meal this fall, and they should all be blooming next spring.

 

Answer 2

When pulling some weeds among my iris I discovered some mushy rhizomes.  So I cut off those parts until I only had healthy ones left.  My question is, will the newly re-planted iris survive being planted the first of June??

Answer 3

Some of the bulbs have to mature a year-or they might have been old bulbs-check where you bought them-

Answer 4

Can u cut down the ires at the end of the summer.

Answer 5

Make sure the top of the rhizones are barely covered. If they are planted too deeply they will not bloom. Also they do not like to be mulched.

Answer 6

How can I transfer wild irises that are growing all over in one of our lots and plant then in our front yard?
