Buddleia or Buddleja are probably one of the most popular garden shrubs, removing faded flower spikes during flowering, (dead heading) will keep all varieties of buddleia, flowering longer throughout the summer.Annual pruning encourages plenty of new growth and larger flowers for the coming year.
Leaving on the last of the flowers and letting them turn to seed, provides food for small birds during the winter months.
When to prune Buddleia or Buddleja
The best time to prune Buddleia is late winter or early spring, just as the new buds begin to swell, cutting away the previous years growth to two or three buds from their base.
Don’t be scared buddleia is a hardy shrub, and generally very forgiving when it comes to pruning, easily surviving an oops or 2 with the cutters believe me, any mistakes will soon be hidden by healthy new growth
Unless you want to remove a branch entirely, to reshape buddleia, do not cut back into the older wood, it is usually thicker and darker coloured as this may not readily sprout new shoots.The pruned shrub will have a low framework of branches from which shoots will grow rapidly to produce flowers in summer.
