Well, I sure applied too much for the plants that died outright or were badly damaged, but the target plant that was showing chlorosis did great. So several different plants responded to the same solution in an extreme way both positive and negative and there were some that showed no effect. It was the fastest result I've ever had using a chemical. Because that area tended to not have available iron that plants could take up, it helped a lot. I actually used it as a herbicide on some plants that didn't like it and had been really hard to eliminate. The Saint Augustine grass got thick and healthy and very green. It was exactly what it was needing. If these daylilies don't need it, it could go either direction or have no effect. Nitrogen hasn't corrected it.
