Q: I have lots of new hostas in my courtyard garden. Some are growing in containers, and others are planted at the front of a small border. Recently, a few of the plants have started to turn yellow. What's caused this, and how can I remedy the problem?
A: Hosta leaves will turn yellow and die back toward the end of the growing season. This is perfectly normal, and they can be removed as you prepare the plants for winter in the late fall. However, if your hosta foliage has lost its usual hue prematurely, it's likely to be a sign of stress caused by environmental factors.
