I am a hobby gardener with no expertise - I have moved lots of iris onto a sunny bed and they bloomed marvelously this spring. But they are huge!! Many have formed large seed pods. I am unsure about when to move them, to thin them, and when (or if) to cut the foliage back.
I, on the other hand, have iris plants but no blooms for 2 years now, and I am perplexed by this. OK, last year, they were bitten by the Easter freeze. Then they were probably stressed when I had to take them up for an exterior paint job on our house, But I replaced them in their beds and they should have bloomed this spring. Alas, nothing!
