Butterfly Bush Growing Tips

Light: Full sun is ideal for Buddleja; it needs at least 6 hours of direct sunlight daily to flourish and produce abundant flowers.

Fertilizer: This plant needs no fertilizer other than a thin layer of compost spread over the root zone each spring.

Pruning: Prompt removal of spent flower spikes will usually promote blooms until frost. Prune in early to mid-spring to allow time for the new growth to mature and flower in the same year. Avoid pruning in winter, as it may lead to frost damage of new shoots.

Propagation: Propagate by hardwood cuttings in autumn or by semi-hardwood cuttings in summer

Pests and Diseases: Watch out for aphids, spider mites, and caterpillars. Buddleja can also be affected by root rot, downy mildew, and leaf spot.
