It is tolerant of a wide range of soil types, from sandy to loamy, and can even grow in poor-quality soil, as long as there is adequate drainage. It prefers full sun but can tolerate partial shade.
The plant is propagated from seeds or cuttings. Seeds are best sown in late winter, and the seedlings can be transplanted once they are large enough to handle. Cuttings can be taken in late spring or early summer from mature plants and rooted in a mixture of sand and organic compost.
Watering Needs
Bidens somaliensis Sherff requires moderate watering during the growing season. The soil should be kept moist but not waterlogged, as waterlogging may lead to root rot. Watering should be done early in the morning or late in the evening, and care should be taken to avoid splashing water onto the leaves, as this may encourage fungal diseases.
In winter, the plant should be watered sparingly to prevent the soil from drying out completely. Overwatering during this period may also lead to root rot.
Fertilization
Bidens somaliensis Sherff does not require much fertilizer but benefits from occasional feeding. A slow-release granular fertilizer can be applied to the soil at the beginning of the growing season. Alternatively, a liquid fertilizer can be used every two weeks during the growing season.
Organic fertilizers such as compost or manure can also be used. These should be mixed into the soil or applied as a mulch around the base of the plant.
Pruning
Bidens somaliensis Sherff does not require much pruning. However, deadheading spent flowers can encourage the plant to produce more blooms. The plant can also be cut back in late fall or early winter to promote new growth in the spring.
If the plant becomes too leggy or unruly, it can be trimmed back to a more manageable size, but this should be done in the fall or early spring.
Propagation of Bidens somaliensis Sherff
Bidens somaliensis Sherff is a perennial herbaceous plant that belongs to the Asteraceae family. It is native to Africa and can grow up to 60 cm in height. The plant has yellow flowers and green leaves, making it an excellent addition to any garden or landscape. The following are the propagation methods of Bidens somaliensis Sherff:
Seed Propagation
The most common method of propagating Bidens somaliensis Sherff is through seeds. The plant produces seeds that can be collected after the flowering period. The best time to collect seeds is when the flower head has turned brown and begins to dry out. To collect the seeds, cut off the dried flower head and shake it over a container to release the seeds.
Once the seeds are collected, they can be sown in a tray or pot filled with a well-draining soil mix. The seeds should be sown shallowly and covered lightly with soil. Keep the soil moist but not waterlogged, and place the tray or pot in a warm, bright location. Germination can occur within two to four weeks.
Cutting Propagation
Bidens somaliensis Sherff can also be propagated through cutting. Take cuttings from the plant in the early summer when it is actively growing. Choose healthy stems that have no flowers or buds and cut them at a length of 7-10 cm.
Remove the leaves from the lower half of the cutting and dip the cut end in rooting hormone powder. Plant the cutting in a pot filled with a well-draining soil mix and cover it with a plastic bag. Place the pot in a shaded area and keep the soil moist. Rooting can occur within two to four weeks, and once rooted, the cutting can be transplanted to a permanent location.
Division Propagation
Bidens somaliensis Sherff can also be propagated through division. This method is best done in the early spring before new growth appears. Dig up the plant carefully, then divide the clump into smaller sections. Each section should have some roots and stems attached.
Plant each division in a pot or a permanent location filled with a well-draining soil mix. Water the divisions regularly and keep them in a shaded location until new growth appears. Once new growth appears, the plants can be moved to a brighter location and treated as mature plants.
Overall, Bidens somaliensis Sherff is an easy plant to propagate and maintain. Whether through seed, cutting, or division, it is a beautiful and valuable addition to any garden or landscape.
