The plant requires full sunlight to grow and should be protected from strong winds.
Watering Needs
Lepidium flexuosum Thunb. requires moderate watering, and the soil should be kept evenly moist, but not waterlogged. Water the plant when the top 2 cm of soil is dry to the touch. In dry weather, water the plants deeply once or twice a week, depending on the soil moisture level and the weather conditions. Ensure that the soil drainage is proper to prevent root rot.
Fertilization
Lepidium flexuosum Thunb. requires fertile soil to grow, but excessive fertilization may harm the plant. It is recommended to add a slow-release organic fertilizer to the soil before planting. Alternatively, use a balanced 10-10-10 fertilizer, diluted to half the recommended strength, every four to six weeks during the growing season. Nitrogen-rich fertilizers should be avoided as they promote foliage growth and do not enhance flower production.
Pruning
Lepidium flexuosum Thunb. does not require pruning, but it is recommended to trim back the plant after flowering to encourage bushier growth and prevent self-seeding. Cut the stems back by half their length, using sharp, clean pruning shears. Remove any dead or damaged foliage and stems regularly throughout the growing season to maintain the plant's health and appearance.
Propagation of Lepidium flexuosum Thunb.
Lepidium flexuosum Thunb., commonly known as twining peppercress, is a creeping or twining herb that belongs to the family Brassicaceae. This plant species is distributed throughout the world and is widely used in traditional medicine.
Seed Propagation
Seed propagation is the most common and easiest method for Lepidium flexuosum Thunb. The seeds of this plant can be directly sown into the soil or seed trays. The best time for sowing the seeds is in late summer or early autumn, which provides enough time for the seeds to germinate before the winter sets in. The seeds should be sown at a depth of 1 to 2 cm, and the soil should be kept adequately moist until the seeds germinate. The seedlings can be transplanted into their permanent position once they have grown 2 to 3 true leaves.
Cuttings Propagation
Another propagation method for Lepidium flexuosum Thunb. is through stem cuttings. Cuttings should be taken during the growing season, preferably in the spring or early summer. The cuttings should be 8 to 10 cm in length, and the leaves should be removed from the lower half of the cuttings. Dip the end of the cutting in rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and place the pot in a warm and bright spot. Rooting may take up to 4 weeks, and once the cuttings have rooted, they can be transplanted into their permanent position.
Division Propagation
Lepidium flexuosum Thunb. can also be propagated through division. This method is best suited for larger and more established plants that have formed clumps. Divide the plant into smaller portions using a sharp, sterile knife, ensuring that each division has enough roots and shoots. Plant the divisions immediately into their permanent position, taking care not to damage the roots.
Overall, Lepidium flexuosum Thunb. is an easy-to-grow plant that can be propagated by seed, cuttings, and division.
