Light Requirements
Sonchus bipontini Asch. forma luxurians R.E.Fr., or commonly known as Creeping sow thistle, grows best in full sun to partial shade. It can still thrive in areas with limited sunlight exposure, but its growth may be stunted.
Temperature Requirements
Creeping sow thistle is a hardy plant that can survive in a wide range of temperatures. However, it prefers temperatures ranging from 18°C to 24°C during the day and 10°C to 15°C at night. When exposed to temperatures higher than 30°C, its leaves may become scorched and wilted.
Soil Requirements
The plant thrives in well-draining soils that are rich in organic matter. It can grow in various soil types such as sandy, loamy, and clayey soils. However, it prefers slightly acidic to neutral soil with a pH range of 6.0 to 7.5.
Moreover, it is essential to ensure that the soil is moist, but not waterlogged, as the plant does not tolerate standing water. Overwatering may also lead to root rot and other fungal diseases.
Cultivation Method
Sonchus bipontini Asch. forma luxurians R.E.Fr., also called Greater Sowthistle, is a herbaceous, fast-growing plant that requires full sun to partial shade for cultivation. It can be grown in almost any soil type, from sandy to loamy and well-drained soil to clayey soils. However, it prefers loamy, well-drained soils that are rich in organic matter.
Watering Needs
The Greater Sowthistle plant requires regular watering, especially during dry periods, to keep the soil moist. However, it is essential to avoid over-watering to prevent soggy soils that can cause root rot.
Fertilization
Greater Sowthistle thrives well in rich, fertile soils. Therefore, it would be best to fertilize your plants with a balanced fertilizer regularly during the growing season. Avoid over-fertilizing, as it can cause excessive vegetative growth, which may reduce the plant's flower production.
Pruning
Pruning is not necessary for the Greater Sowthistle plant. However, if you want to control its size and shape or ensure continuous blooming, you may clip off the spent flowers regularly. Also, cutting back the stem can stimulate growth, and it is best done in early spring when the plant is still dormant.
Propagation of Sonchus bipontini Asch. forma luxurians R.E.Fr.
Sonchus bipontini Asch. forma luxurians R.E.Fr., also known as the Great Burdock, is commonly propagated by seeds. However, it can also be propagated by root cuttings.
Propagation by Seeds
Propagation by seeds is the most common method used by gardeners to propagate Sonchus bipontini Asch. forma luxurians. The best time to start planting seeds is in late spring or early autumn. The seeds should be sown in seed trays or pots, with a well-draining potting mix. The seeds should be sown to a depth of 1 cm and spaced out around 5 cm apart. Keep the soil moist, and germination should occur within 14 to 20 days. Once the seedlings have developed two true leaves, they can be transplanted to their permanent location in the garden.
Propagation by Root Cuttings
Propagation by root cuttings is another method to propagate Sonchus bipontini Asch. forma luxurians. This method involves taking a section of root from an already established plant and placing it in a well-draining potting mix. The root cutting should be around 5-10 cm long, and its diameter should be approximately that of a pencil. The cutting should be placed horizontally in a potting mix and kept moist at all times. Once the cutting has produced new growth and a good root system, it can be transplanted to the garden.
