Brown spots on evergreens
Hi. We have 8 of these ornamental evergreen shrubs around the foundation of our house. 2 of them have developed brown spots with dead needles. The others look fine. Can you advise us as to the problem and how to treat it?
We live in SW Missouri about 40 miles South of Joplin. We appreciate any assistance you can provide.
I have included photos of the healthy looking shrub and the affected shrub.

These were planted in 2014. They were fertilized in October 2017 with evergreen granules. They are about 3 feet apart, and side by side. It has been very hot and dry for the last 4 to 5 weeks but they are watered once/week for 2.5 to 3 hours using a drip irrigation system. I checked the system and it is working. They are on the East side of the house. Not new construction. House was built in 1930. Thank you.
