Propagation of Pauridiantha butaguensis var. exsertostylosa
Pauridiantha butaguensis var. exsertostylosa can be propagated both by sexual and asexual methods.
Sexual Propagation
The seeds of Pauridiantha butaguensis var. exsertostylosa can be sown directly into the soil in a well-draining potting mix. The ideal temperature for germination is between 20°C and 25°C.
Before sowing, the seeds can be soaked in water for 24 hours to facilitate germination. Seeds that have not been soaked can have a longer germination period.
Once the seeds have been sown, the soil should be kept moist until germination occurs. The seedlings will generally appear within 2-4 weeks.
Asexual Propagation
Pauridiantha butaguensis var. exsertostylosa can be propagated asexually through stem cuttings. The best time to take the cuttings is during the spring or summer when the plant is actively growing.
The cuttings should be taken from healthy, disease-free plants. The stem cuttings should be at least 10 cm long and should have at least two to three nodes. The leaves on the lower nodes should be removed, and the cutting should be dipped in rooting hormone before planting it in a well-draining potting mix.
The cutting should be placed in a propagator or covered with a plastic bag to maintain humidity. After four to six weeks, the cutting should have developed sufficient roots to transplant into a larger pot or out into the garden.
