Pruning
Alectra sessiliflora (Vahl) Kuntze var. barbata (Hiern) Hilliard & B.L.Burtt does not require pruning as it has no stem or leaves. However, it's essential to remove any damaged or dead host plant parts to prevent further damage to the growing Alectra sessiliflora.
Propagation of Alectra Sessiliflora (Vahl) Kuntze var. Barbata (Hiern) Hilliard & B.L.Burtt
Alectra sessiliflora (Vahl) Kuntze var. barbata (Hiern) Hilliard & B.L.Burtt can be propagated through both seed and vegetative means.
Seed Propagation
The seeds of Alectra sessiliflora (Vahl) Kuntze var. barbata (Hiern) Hilliard & B.L.Burtt can be sown during the rainy season in the natural habitat of the plant. The seeds can be collected when the fruits start to dry and can then be stored in a cool and dry place until the next rainy season.
Before sowing the seeds, they need to be scarified, as they have a hard seed coat that prevents germination. Scarification can be achieved by rubbing the seeds with sandpaper or by soaking them in warm water for 24 hours before sowing.
The seeds should be sown in a seedbed that is well-drained and enriched with organic matter. The soil should be kept moist, but not waterlogged, until germination occurs. The seedlings should be transplanted into individual pots once they have developed their first set of true leaves.
Vegetative Propagation
Alectra sessiliflora (Vahl) Kuntze var. barbata (Hiern) Hilliard & B.L.Burtt can be propagated vegetatively through stem cuttings.
The stem cuttings should be taken from mature plants during the growing season and should be around 10 cm in length. The cuttings should be dipped in rooting hormone and then planted in a well-drained potting mix that is moist but not waterlogged.
The cuttings should be kept in a warm and humid environment until they develop roots and start growing. Once the new plants have grown to a suitable size, they can be transplanted into individual pots or directly into the garden.
Disease and Pest Management of Alectra sessiliflora (Vahl) Kuntze var. barbata (Hiern) Hilliard & B.L.Burtt
