Propagation of Sonchus bipontini Asch. var. exauriculatus Oliv. & Hiern
Sonchus bipontini Asch. var. exauriculatus Oliv. & Hiern, commonly known as the dwarf sowthistle, is a herbaceous plant native to the Mediterranean region. It belongs to the family Asteraceae, and it is commonly grown as an ornamental plant. It is a quick growing plant that needs little maintenance and can adapt to various different environments. Propagation of this plant is possible through different methods that are not too complicated.
Propagation by seeds
Propagation by seeds is the easiest and most common method. Seeds should be collected from mature plants after the flowering season, which is usually in late summer or early autumn. The seeds need to be sown immediately, and it is better to do it during autumn or early spring. The soil should be previously prepared, ensuring it is not too compact, and adding organic matter to enrich it. Seeds should be sown at a depth of around 2-3mm, and after sowing, the soil should be kept moist until the seedlings emerge. Once the seedlings appear, they should be thinned out to ensure they are not overcrowded and have space to grow.
Propagation by cuttings
Propagation by cuttings is also possible for Sonchus bipontini Asch. var. exauriculatus Oliv. & Hiern. The cutting material should be taken from young shoots in spring or early summer. The cuttings should have a length of around 10- 12 cm, and they should be made just below a node. Cuttings should be dipped in rooting hormone powder and planted in a well-draining and moist soil. The soil should be kept moist until roots form, and then the cuttings can be planted outdoors.
Propagation by division
Propagation by division can be done in spring or autumn when the mother plant is dormancy. The plant needs to be dug out, and the root bulb should be carefully divided into sections. Each section should have at least one shoot or bud. After division, the divided plants should be replanted in a well-draining and moist soil. Water the plant immediately after replanting, and regularly until new growth appears.

Diseases
Fungal Root Rot: This is a common disease that can affect Sonchus bipontini Asch. var. exauriculatus Oliv. & Hiern, particularly in wet and humid conditions. The disease causes the lower leaves to yellow and wilt, and the roots to rot.
Management: To manage fungal root rot, it is essential to provide the plant with well-drained soil. Avoid overwatering or watering the plant at night when there is no sun. In case the plant is already infected, remove and dispose of the affected plant parts.
Pests
Aphids: Aphids are tiny, pear-shaped insects that may appear in large numbers around the growing tips, buds, and flowers of Sonchus bipontini Asch. var. exauriculatus Oliv. & Hiern. They feed on plant sap and secrete honeydew, which attracts other pests like ants and spreads fungal diseases.
Management: To manage aphids, you can spray the plant with insecticidal soap or neem oil. Alternatively, you can use a strong jet of water to dislodge the aphids from the plant. Introducing ladybugs, lacewings, or hoverflies to the garden can also help control aphids.
Slugs and Snails: Slugs and snails are common pests that feed on the leaves of Sonchus bipontini Asch. var. exauriculatus Oliv. & Hiern. They leave behind large holes and shiny mucus trails.
Management: To manage slugs and snails, you can create a barrier around the plant using copper strips, diatomaceous earth, or eggshells. You can also handpick and dispose of the pests or use traps like beer traps. Applying iron phosphate baits or using nematodes can also help control the pests.
In conclusion, Sonchus bipontini Asch. var. exauriculatus Oliv. & Hiern rarely suffers from diseases and pests. Managing the few common problems is relatively easy, and the plant can thrive for years, providing a lovely addition to your garden.
