Propagation of Holothrix squamulosa Lindl. var. scabra Bolus
Holothrix squamulosa Lindl. var. scabra Bolus can be propagated in two ways:
Propagation through Seeds
The plant produces small, round, black, and papery seeds, which can be collected after the flower has faded away. The collected seeds can be stored in the dry and cool place for future use.
Before sowing the seeds, they should be scarified to break the hard seed coat. The seeds can be scratched with sandpaper or nicked with a knife. After scarification, the seeds should be soaked in water for 24-48 hours to improve germination.
After preparing the seeds, sow them in a well-draining, sandy soil mix, covering them with a thin layer of soil. Keep the soil evenly moist and maintain a temperature of around 20°C to 25°C. Germination should occur within 2-3 weeks.
Propagation through Division
Another propagation method is through the division of the plant. This method is suitable for mature plants that have clumped together.
It is best to divide the plant during the growing season. Dig up the plant and separate the roots and rhizomes, making sure each section has its roots and leaves. Trim off any damaged or dead roots. Plant each section in a well-draining soil mix and keep the soil evenly moist until the new plants are established.
Propagation through division is a quick and easy way to propagate Holothrix squamulosa Lindl. var. scabra Bolus, and it can help to revitalize older plants.

- Destroy any infected plant material to prevent the spread of the disease.
Common Pests
1. Aphids: Aphids are small, soft-bodied insects that suck sap from the plant. The insect infestation can lead to stunted growth and yellowing of leaves.
Management: To manage aphids, you should take the following precautions:
- Spray insecticidal soap or neem oil on the plant to kill the aphids.
- Introduce natural predators like ladybugs to control the population of aphids.
2. Spider mites: Spider mites are tiny mites that feed on the sap of the plant. They can cause yellowing of leaves and the appearance of webs on the plant.
