I was talking to a guy at the Home Garden Area at HD today. He had some other suggestions, 1) I am using Midnight mulch, he said it could be too hot and it doesn't absorb water well, making it run off my plant. 2) He said it could be too close to brick or concrete, however mine are just flowerbed stones. He said it could be reflecting heat, what do you think, could this be it? Thx

Hmm.. I think we are really grasping at straws here. Your other coneflowers are doing well and they are in the same bed with the same mulch so I'm not convinced that it is too hot, although if the mulch is thick, it could very well be shedding the moisture before it can trickle down to the root system of your plant. An easy fix is to rake away the mulch and see if that does the trick. I don't think reflected heat is the problem. I'm sticking to my original diagnosis - root stress. Either damaged or diseased roots or a problem with too much/ too little moisture. Try the shade cloth draped over 4 stakes, or move the plant to a site that has morning sun and afternoon shade. This particular plant just doesn't seem to be thriving under normal sunny conditions so you may have to baby it along. Good luck with your coneflower.
