Propagation of Polycarpon tetraphyllum (L.) L.
Polycarpon tetraphyllum (L.) L. can be propagated by seeds, cuttings, and division method.
Propagation by Seeds
The seeds of Polycarpon tetraphyllum (L.) L. can be sown directly into the soil in pots or seed trays. The best time to sow the seeds is in the spring or autumn. The soil should be well-drained and slightly alkaline with a pH of around 7.0.
Before sowing the seeds, they should be soaked in water for 24 hours to enhance their germination. Then, spread the seeds evenly on the soil surface and cover them lightly with soil. Water the soil regularly and keep it moist until germination occurs, which usually takes around two weeks.
Propagation by Cuttings
The cuttings of Polycarpon tetraphyllum (L.) L. can be taken in the summer. Select a healthy stem and cut a 4-5 cm long piece from the tip. Remove the leaves from the lower half of the cutting and dip the cut end in rooting hormone powder.
Then, plant the cutting in a mixture of equal parts peat moss and sand. Water the soil and cover the pot with a plastic bag to create a humid environment. Place the pot in a shaded area and keep the soil moist until roots start to develop, which usually takes around four weeks.
Propagation by Division Method
The division method of propagation is best done in the spring. Dig up the plant and carefully separate the clumps of roots with a sharp knife. Ensure that each clump has at least one shoot and a sufficient amount of roots.
Plant the divided clumps in a well-drained soil mixture and water them well. It is essential to keep the soil moist until new growth appears, which usually takes around two weeks.
