Answer: Boxwoods are usually carefree hedging plants so I'm not sure what might be wrong with your plant. If it is turning brown, there's a root problem. The most common is root rot from poorly draining soils. But the browning might also be caused by dog urine or from lack of water. I can't really diagnose the problem without seeing the plant. Try watering once each week - twice a week when the weather is really hot. When you water, apply the water slowly so it has a chance to soak into the soil. Inspect the plants for signs of insects, as well. Wish I could offer more help!
