Butterfly Bush 'Pink Delight' problems — and how to fix them
Butterfly Bush 'Pink Delight' (Buddleja davidii 'Pink Delight') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor or sparse flowering
Most often from inadequate sun or no annual prune. Plant in full sun and cut back hard in early spring to force flowering new wood.
Invasive self-seeding
Prolific seeder, invasive in some US states and parts of the UK. Deadhead before seed disperses, or remove unwanted seedlings promptly.
Spider mites in heat
Stippled, dull leaves and fine webbing during hot, dry spells. Raise humidity around the plant, hose foliage and support natural predators.
Powdery mildew
Whitish film on leaves in crowded, humid sites. Thin growth, improve air movement and avoid wetting the foliage.
