Q.Iris Plants Had Too Much Rain This Summer
My Immortality irises are usually reblooming, but show no signs of it after a summer of rain. Will they com e back as good as new next year? Is there anything I can do to help. Can I thin them out this Fall?

Bearded irises can rot if they get too much water. If your soil is well draining, the summer rains hopefully did not damage them. Reblooming is not guaranteed, so it may not have been the rain that stopped fall blooming.
If the stands are crowded, or they have been growing for at least three years, you can dig them up and divide them. Wait till a day when they have dried out, however.
