• Rejuvenation: Every few years, trumpet lilies benefit from rejuvenation through a moderate division of bulbs and removal of overcrowded or non-productive growth.

Propagation

The propagation of Lilium ‘Thunderbolt’ enables enthusiasts to expand their trumpet lily collection and share the beauty of these plants with others. Understanding the various propagation methods, such as division, bulblet formation, and seed propagation, equips individuals with the knowledge to propagate trumpet lilies successfully.

Propagation Methods

Division

Division is the most common and reliable method of propagating trumpet lilies. This process involves separating the bulblets or scales from the parent bulb and transplanting them to a predetermined location.

Division Process:

• Gently dig up the lily bulbs during the dormant season, ensuring minimal damage to the scales.
• Separate the individual bulblets or scales from the parent bulb, ensuring each division possesses viable roots and a growing point.
• Transplant the divisions into prepared planting sites or containers, providing appropriate care until they establish themselves.

Bulblet Formation

Bulblet formation occurs naturally as trumpet lilies age and develop small, daughter bulblets around the parent bulb. These bulblets can be carefully separated and replanted, initiating new plants.

Bulblet Propagation:

• Wait until the bulblets develop into viable, independent bulbs before carefully detaching and transplanting them.
• Provide adequate care to the newly separated bulblets, ensuring they have suitable growing conditions and maintenance.

Seed Propagation

Seed propagation is a more labor-intensive and time-consuming method compared to division or bulblet formation. However, it offers the opportunity to produce new Lilium ‘Thunderbolt’ hybrids and explore genetic diversity.

Seed Propagation Steps:

• Collect mature seeds from the trumpet lily once the seed pods have ripened and split.
• Sow the seeds in a suitable germination medium and provide the necessary conditions for successful seedling establishment.
• Select and transplant vigorous seedlings into individual containers or prepared planting sites after they have reached an appropriate size and maturity.
