What does sm.rhizomes lined out mean?

Question

I live in Las Cruces, New Mexico and my Iris failed to bloom 2 yrs in a row. They were dug up in November and transpanted in March. Did I kill them?

Answer 1

Digging them up will usually set back blooming for a year or two if not done at the correct time. Irises are best dug up and transplanted in late summer while they are dormant. There are many other reasons as well.
