One of our hydrangeas has had 3 (2+ foot long) stems break off at the soil. I first noticed wilt, then thinking the rain had beat them down, tried to 'up' them, and they came off at ground. I find no signs of any pests, and we've had only 1/2 inches of rain in the past week. What should I do?

In the meantime, give it some water. https://www.gardeningknowhow.com/plant-problems/environmental/how-to-tell-if-a-plant-is-dead-and-how-to-recover-an-almost-dead-plant.htm
