Cutting back Buddleia
Hi, i have a buddleia at the front of the house which was about 5/6ft when i moved house in 2006 and it never got pruned. Consequently it grew to about 20ft and was starting to attack the guttering. I cut it back to about 5ft in September and I know that I should cut it back further in March time but one side is lots of stems from the ground that I can cut but one side is a thickish trunk with stems only starting about 3-4ft up. I have attached a picture. Please could anyone give any advice what is the best way to tackle this buddleia.
