There is a little missing information, but I believe that looks a little like aphid damage... That being said, there are several things you could do. A little dish soap and water can help, but try not to spray the soil so much. My preferred method is a product from Foxfarm called Force of Nature Miticide. Use 1oz per gallon about a fourth oz for a spray bottle.

Making sure the newly planted shrubs receive adequate watering while setting down roots can be more difficult in the warm summer months.
Keeping the roots cool and moist with a layer of hardwood mulch will help.

Watering should be daily during the first 2 weeks and then you can back off slightly, but will need to monitor the soil moisture carefully.
Maintain the watering schedule until the fall when plants began to go dormant.
Pruning can take place in the spring of any dead plant material.
