Propagation of Adenandra humilis Eckl. & Zeyh. var. pubescent Sond.
Adenandra humilis Eckl. & Zeyh. var. pubescent Sond. can be propagated by seeds, cuttings and layering.
Propagation by Seeds
Seeds can be sown in trays filled with a well-draining seed starting mix. The seeds should be covered lightly with soil and kept moist. They require bright, indirect sunlight and warm temperatures to germinate. The ideal temperature for germination ranges from 18-22°C (65-72°F).
Once the seedlings emerge, they should be thinned out to ensure that they have enough space to grow. Seedlings can be transplanted to larger pots once they have developed 2-3 sets of true leaves. They can be planted outdoors once they are large enough to handle the environmental stressors.
Propagation by Cuttings
Take cuttings in the summer months, when the plant is actively growing. Select a healthy cutting that is around 5-10 cm long and has a few leaves on it. Cut the stem at an angle and dip it in rooting hormone. Place the cutting in a well-draining potting mix and keep the soil moist. The pot should be covered with a clear plastic bag or placed in a propagator to provide adequate humidity.
The cutting should develop roots within 6-8 weeks. Once the roots have established, it can be transplanted to a larger pot and grown indoors until it is large enough to be planted outdoors.
Propagation by Layering
Layering is a propagation method where a branch of the parent plant is bent and secured to the ground. This part of the stem is covered with soil leaving the tip of the branch exposed. Over time, roots will develop and grow into the soil, creating a new plant. Once the new plant is established, it can be separated from the parent plant and transplanted to a new location.
