My Spirea appear to be dying

All 6 of my plants have dead spots. It has been extremely hot and dry here. The middle of the plants at the base also have spider webs. I have started watering them, but wonder what else I should be doing for them. I have been told they do not get spider mites, but maybe they have something else that leaves webs. Should I cut off all the dead branches?

Most likely it is a combination of heat/drought stress and a pest infestation, like spider mites–which do in fact affect these shrubs. Try upping the water and treat the plant with neem oil, which will take care of the pest and is a fungicide as well.

Do I have to wait for cooler temperatures before applying the neem oil? We have been in a heat wave. thankfully we are getting rain.
