Why are my boxwood shrubs turning yellow and dying?

Homeowners trying to save boxwoods during hot and dry weather often increase watering frequency, only to watch the foliage get progressively worse and develop yellow or brown patches. This leaves them guessing whether the shrubs are suffering from a reversible seasonal change, severe drought stress, or a disease like blight, and unsure whether trimming the damaged bits will help.

“Is this dying? Blight? This is one of five boxwoods I planted about 3 years ago, but the only one yellowing/browning.”source ↗

“Is it reversible? Maybe just seasonal yellowing (but seems like the other 4 would be doing it too). Should I trim the yellowing bits off?”source ↗
