Soil requirements:
Venidium semipapposum DC. prefers well-draining soils that are rich in organic matter. It can grow in a variety of soil types, including loam, sandy loam, and clay loam soils. The pH of the soil should be slightly acidic to neutral (between 6.0 and 7.5). The plant is not tolerant of waterlogged soils, and as such, adequate drainage is critical to its growth.

Propagation of Venidium semipapposum DC.
Venidium semipapposum DC. can be propagated both by seeds and cuttings. The propagation method depends on the purpose of the propagation. For instance, if you want to propagate the plant to get more plants, seeds are a good option.
Propagation by Seeds
You can collect the seeds of Venidium semipapposum DC. from the plants when the seed pods are dry and brown. Once you have collected the seeds, you can sow them in the soil. The best time to sow Venidium semipapposum DC. seeds is in early spring or fall.
Before sowing the seeds, prepare the soil by adding organic matter and ensuring it is moist. Water the soil before sowing the seeds to make it compact. Sow the seeds half an inch deep and cover them with soil. Keep the soil moist until the seeds start germinating. The germination period for Venidium semipapposum DC. is between two and four weeks.
Propagation by Cuttings
You can propagate Venidium semipapposum DC. by using stem cuttings. Choose a healthy stem and cut off a six-inch section using a sharp, clean knife. Remove the leaves from the lower half of the stem and dip it in rooting hormone powder.
Fill a pot with well-draining soil and insert the cutting into the soil. Keep the soil moist and place the pot in a shaded area. The cutting should root within a few weeks, and you can transplant it into a larger pot or outside if the weather permits.
Make sure you keep the cutting in a warm, humid, and shaded environment until it starts putting on new growth.
