When the flowering period comes to an end, a butterfly bush is littered with withered flowers. This circumstance initially affects the appearance, while countless seeds develop in secret. So the question is definitely justified. Read here why faded flowers on Buddleja davidii should go.
Why should you cut off spent flowers on the butterfly lilac?
Withered flowers on butterfly lilac should be cut off to prevent uncontrolled spread by seeds. Cut off the withered inflorescences just above the next leaf node or bud and dispose of the cuttings in household waste.
Cutting off wilted flowers stops the spread
Its limited winter hardiness down to -20 degrees Celsius does not prevent a butterfly bush from acting as an invasive neophyte in the garden. This property results less from strong root growth than from its countless seeds. So that the majestic buddleia species does not act as a plant imperialist, cut off the dead flowers in good time. This is how it works:
- Clean out wilted inflorescences during and after the flowering period
- Use the scissors in time before the capsule fruits grow
- Make the cut just above the next leaf node or bud
So that the seeds don't find their way into the bed from the compost, please dispose of the clippings in the household waste.
