The plant produces a significant amount of seeds, and they remain viable for a few years. The seeds can be collected from the plant after the flowering period and stored in a cool, dry place.
Before planting the seeds, they should be scarified to increase germination rates. To scarify the seeds, they can be nicked with a knife or rubbed with sandpaper.
The seeds can be planted in trays or pots filled with a well-draining potting mix. The soil should be kept moist, but not waterlogged. The seeds will germinate in about 2-3 weeks, and when the seedlings have developed two or three leaves, they can be transplanted into larger pots or directly into the garden.
Cutting Propagation
Another method of propagating Celsia pedunculosa Steud. & Hochst. ex Benth. var. pedunculosa is through stem cuttings. This method is useful for producing identical plants and is commonly used for commercial propagation.
To take cuttings, select healthy stems and cut them just below a node, using a clean and sharp knife. Remove the lower leaves, leaving just a few at the node. Dip the cuttings in a rooting hormone powder and plant them in a well-draining potting mix. Water the soil and cover the pots with plastic bags to retain moisture.
The cuttings should be kept in a warm area with bright, indirect sunlight. Roots will develop in about 3-4 weeks, and when the plants have developed a good root system, they can be transplanted into larger pots or directly into the garden.
Disease and Pest Management for Celsia pedunculosa Steud. & Hochst. ex Benth. var. pedunculosa

Common Diseases and Their Management
One common disease that affects Celsia pedunculosa is powdery mildew. Powdery mildew is a fungal disease that presents as a white, powdery coating on the leaves and stems of the plant. To manage powdery mildew, remove any infected leaves and stems as soon as possible. Avoid overhead watering and improve air circulation around the plant by pruning back nearby vegetation. Use a fungicide spray if necessary.
Another common disease is leaf spot. Leaf spot presents as dark spots on the leaves that eventually turn yellow and drop off. To manage leaf spot, remove any infected leaves and dispose of them. Improve air circulation around the plant and avoid wetting the foliage. Use a copper-based fungicide according to package directions.
Common Pests and Their Management
One common pest that affects Celsia pedunculosa is aphids. Aphids are small, pear-shaped insects that suck the sap from the leaves and stems of the plant. To manage aphids, spray the plant with a strong jet of water to dislodge them. Use insecticidal soap or neem oil if necessary.
Another common pest is spider mites. Spider mites are tiny pests that feed on the underside of leaves, causing them to turn yellow and fall off. To manage spider mites, remove any heavily infested leaves and dispose of them. Improve air circulation around the plant and avoid overwatering. Use a miticide according to package directions.
Regularly inspecting the plant for signs of disease or pest infestation is important to catch any problems early. Proper plant care, including regular watering and fertilizing, will help keep the plant healthy and less susceptible to disease and pest problems.
