My Shirey that I set out the last week of April is doing well, growing tall, about 5' and with some nice large leaves. They are starting to develop a flower head and I am wondering if this is the proper time to top the plants.
Here is an image of the largest plant that shows the development of the flower head to date.

Is this the proper stage for topping, or should I let it grow for a while longer?
