Buddleia Flower Power - does anyone when/how to prune? Some websites say prune hard after flowering, but I've also seen advice that buddleias in general should be pruned hard in early spring. My plant is 2 years old and about 2 feet high at present - it doesn't seem to grow very fast. Any Flower Power owners out there could advise me please?
