Q.My Afterglow Hosta Only Has 4 Leaves. The Plant Is 4 Years Old, And The Leaves Look Healthy. What’s Wrong?
I have a 4 year old Afterglow hosta that only has 4 leaves on it. The leaves look healthy. The hosta is planted in a huge pot that sits in a partial shade spot in my garden.

It sounds like the container is too large for the plant to thrive. This can cause the plant to stay too wet for too long. Try planting it in the ground or in a smaller container with rich, well draining soil.
