Need help with Iris pallida variegata argenta
Several years ago I bought two of these plants and they have bloomed beautifully and grown to about 8 plants to-date. I have just realized that they have not bloomed this year and on inspecting the foliage I noticed papery brown stripes down the edges of several of the leaves (see pics.). I have had an infestation of Iris borer on the bearded Iris clump with is right next to these some years ago, but this does not look like Iris borer to me. Any ideas of what the problem might be? I'd appreciate any suggestions - moving, fertilizing? Thank you.
