Certain spots in my hedges are yellow and the branch is dead. What causes this?

Root stress is the usual cause of dead branches on viburnums and boxwoods. Not necessarily diseased, but stress from too much or too little water. You can safely prune out the dead branches, removing them down as far as possible. To prevent this from happening again, be sure to check the soil moisture before watering. Sometimes we place our plants on an automatic watering schedule and that's not always the best course of action. Water as usual and then wait 3-4 days and dig down into the soil. If the soil is still moist an inch below the soil surface you won't need to water for a few more days. If it is dry, it's time to water. Best wishes with your landscape.
