buddleia stems

shelleyh(z5 NY)March 22, 2014

I have 2 buddleias that are about 12 years old and the stems are very thin on top compared to the original bottom stems that were there when I planted them. I cut them down every Spring to around a foot. Should I not cut them back in order to allow the top stems to thicken? What will happen to the plants if I don't cut them back?

If they bloom on new wood, which is why it is recommended to cut them back every spring, then they wouldn't bloom as much if not cut back.
Every few years, you can cut the bigger, older stems all the way to the ground, and let some of the younger stems grow. This can rejuvenate the plant.
