Re: Pruning a buddleia

Buddleias should be pruned March/April time. They flower on new wood. If flowering is over or you really need to prune now then prune the branches back by about a third.
When new growth begins in Springtime you can cut back to around 8 inches.
I hope this helps sort out your problem.
