Due to drought I have watered more than usual this summer. Now some of my iris in one area look kind of sickly. These are planted in front of a stone wall that is part of my 2 level raised bed. Most of my iris leaves as well as my daylilies look a bit sad, but these are yellowed and spotty. Since it's a raised bed with loose amended soil I was not expecting any problems with drainage. This is a mixed bed with iris, daylilies, and other perennials. I am wondering if the conditions I am providing for the others do not suit the iris. In the previous bed they were all together with no problems.

Would the position next to the wall cause that area to retain more water? The irises away from the wall all look fine (with allowances made for time of year). Should I pull off some of the sickly leaves?

Very few bloomed this year either; they were transplanted into this new bed last summer (2004) and grew leaves like weeds. But very few flowers.
