I'm not a plant guy so looking for some help. We have had some really hot(100+ degrees) and dry days. Getting a break from both this week. I redid our landscape this past feburary so most plant have been in the ground for about 5 months. All were looking nice and healthy up until now. The Yews, rhododendrum, and acuba all look nice and healthy. The hydrangeas(i know the heat has worked on them), fothragilla, barberries, and some of the sweet shrubs are looking pretty bad. Wilting and leaf edges turning brown. Most plants get hit by the pop up or rotor sprinklers. I've been running them daily for the last 3-4 weeks since I've done some lawn work. I may have fertilized at installation, but other than that they haven't gotten anything other than overspread from my lawn(which I've done 3 times in the past month) Will they make it? What can I do? Hand water?
