Answer: It is really difficult to diagnose a problem like this without seeing the plant. Yellowing leaves are more likely due to overwatering than anything else, although overfertilizing can cause similar symptoms. Roses should be watered deeply only once or twice a week in the summer time. Water deeply and then allow the top of the soil to dry out slightly before watering again. You might try digging down into the soil to see how well it is draining/holding moisture 3-4 days after a thorough watering. If it is still moist, you wont' have to water for a few days. If it is dry, it's time to water. Hope your rose bush recovers!
