Cone flower transplants

We have had nice, cool, rainy weather for a few days.  I decided to transplant coneflowers while it was so perfect.  Unfortunately, the heat is back. Tomorrow the temperature will be in the 90's and sunny.  Not good for my babies.  I have to get my misters up and running.  The garden has not needed any extra watering for a good while, but if I am going to save the transplants, they will need help.  I am also going to mulch around them.
