Pruning Butterfly Bush (Buddleia): Cut Hard in Fall

A North Carolina gardener has two large butterfly bushes with dead wood underneath. Asks about pruning timing and deadheading.

Expert's Method: Hard Fall Cut

Cut all the way back to 2-3 feet in fall. Looks like sticks, but next spring they regrow vigorously and bloom beautifully.

Deadheading

Optional. Removing spent blooms can encourage more flowers, but not required. Fall hard prune is the main event.

Why It Works

Butterfly bushes bloom on new wood. Hard pruning stimulates strong new growth = more flowers. They're very forgiving.
