Propagation of Justicia diclipteroides Lindau subsp. kibarianiensis Hedrén
Justicia diclipteroides Lindau subsp. kibarianiensis Hedrén is propagated by stem cuttings or seeds. The plant can be propagated at any time of the year, but it is best to do so during the growing season for the best results.
Propagation by stem cuttings
Stem cuttings are the most common way to propagate Justicia diclipteroides Lindau subsp. kibarianiensis Hedrén. Take a 10-15cm (4-6 inch) long stem cutting from a healthy plant, making sure that it has at least two nodes. Remove the lower leaves and dip the cut end of the stem in a rooting hormone powder. Place the cutting in a pot with a well-draining potting mix and keep it in a bright, shaded area with consistent moisture. After 4-6 weeks, the stem cutting should develop roots and can be transplanted into a larger pot or outdoors.
Propagation by seeds
Justicia diclipteroides Lindau subsp. kibarianiensis Hedrén can be propagated by seeds, but it can take longer than stem cuttings. Sow fresh seeds in a well-draining potting mix and keep the soil consistently moist. Place the pot in a bright, shaded area with a temperature of around 21-24°C (70-75°F). The seeds should germinate in 2-3 weeks. After the seedlings have grown to a suitable size, they can be transplanted into larger pots or outdoors.
