Care Instructions
Showy Mullein thrives in full sun and prefers moderate temperatures. It is drought-tolerant and does not require frequent watering. The plant can handle low humidity levels and is generally easy to care for, making it suitable for outdoor gardens.
Soil
Verbascum speciosum prefers well-draining loamy soil. It can tolerate poor soil conditions but performs best in moderately fertile soil. Ensure the soil dries out almost completely between waterings to prevent root rot.
Fertilizer
This plant does not require regular fertilization. If desired, a light application of a balanced fertilizer in early spring can promote growth, but it is generally not necessary.
Repotting
Repotting is not typically required for Verbascum speciosum as it is usually grown directly in the ground. If grown in a container, repotting should be done in early spring before new growth begins.
Propagation
Verbascum speciosum can be propagated by seeds or root cuttings. Seeds should be sown in late spring or early summer, while root cuttings can be taken in late autumn or early winter.
Pruning
Pruning is not necessary for this plant. However, removing spent flower spikes can encourage a tidier appearance and may promote a second flush of blooms.
