Dip the cuttings in rooting hormone and plant them in a well-draining potting mix. Cover them with a clear plastic bag or plastic wrap to create a mini greenhouse. Place the pot in a warm, bright spot and ensure the soil remains moist. Within 3 to 4 weeks, the cuttings will have formed roots and can be transplanted into individual pots.
Division Propagation
If the plant has an established root system, it can be propagated through division. Dig up the plant gently and divide it into smaller sections, ensuring that each section has a healthy root system. Replant the divided sections into individual pots filled with well-draining potting mix. Water the plants thoroughly and ensure they are placed in a warm, bright spot.
Whichever method you choose, ensure that the young plants are well cared for and protected from extreme weather conditions. With proper care, your Helichrysum zwartbergense Bolus plants will thrive and reward you with beautiful yellow flowers.
