Cultivation methods for Bidens ruyigiensis T.G.J.Rayner
Bidens ruyigiensis T.G.J.Rayner can be propagated by seed or cuttings. For propagation by seeds, they must be sown in a well-drained seed-raising mix and placed in a bright, warm, and semi-shaded location. Germination may occur within 2-3 weeks. Cuttings, on the other hand, should be taken during the growing season and inserted into a well-draining, moist potting mix.
When planting Bidens ruyigiensis T.G.J.Rayner, choose a site with well-draining soil and ample sunlight. It prefers a fertile soil base that contains organic matter, but it will also tolerate sandy soil. They grow well in gardens, pots, and hanging baskets.
Watering needs for Bidens ruyigiensis T.G.J.Rayner
The Bidens ruyigiensis T.G.J.Rayner prefers well-drained soil that is evenly moist but does not require frequent watering. Overwatering may cause root rot and other fungal diseases. To prevent this, water only when the topsoil is dry to the touch.
It is best to water the plant in the morning or evening to avoid water loss due to evaporation and to reduce the risk of fungal infections. During the hot summer months, it may require more frequent watering, and during winter, it may need a little less often.
Fertilization for Bidens ruyigiensis T.G.J.Rayner
Bidens ruyigiensis T.G.J.Rayner needs regular feeding to promote healthy growth and flowering. You can add controlled-release pellets into the soil at planting, or apply a liquid fertilizer every two to three weeks during the growing season.
When fertilizing, always follow the manufacturer's instructions. Excessive fertilization can burn the plant and negatively affect its overall health.
Pruning Bidens ruyigiensis T.G.J.Rayner
Bidens ruyigiensis T.G.J.Rayner does not require much pruning. However, it may help to pinch back any leggy or floppy stems to encourage branching. Deadheading spent blooms can also promote continued flowering.
Remove any damaged or diseased stems as soon as possible to prevent the spread of disease. Additionally, regularly inspect the plant for any sign of insects or pests, and treat them promptly.
Propagation of Bidens ruyigiensis T.G.J.Rayner
Bidens ruyigiensis T.G.J.Rayner can be propagated through different methods which include:
Seed Propagation
Bidens ruyigiensis T.G.J.Rayner can be propagated from seed. Seeds can be obtained from a mature plant. The seeds can then be sown in fertile soil that is moist and well-drained. The seeds should be sown at a depth of about 1 cm and should be kept moist until they germinate. Germination usually occurs after 14 to 28 days. The seedlings can then be transplanted to individual pots.
Cuttings Propagation
Bidens ruyigiensis T.G.J.Rayner can also be propagated through stem cuttings. Cuttings can be taken from a mature plant and should be about 10 to 15 cm in length. The bottom of the cutting should be dipped in rooting hormone before planting in a well-draining potting mix. Cover the pot with a plastic bag to maintain humidity and place in a warm place with bright but indirect light. Rooting usually occurs after 2 to 4 weeks.
Division Propagation
Bidens ruyigiensis T.G.J.Rayner can also be propagated through division. This method is more suited for more mature plants that have multiple stems and are at least 2 years old. The plant should be dug out of the soil and the root ball should be teased apart into smaller clumps. The clumps can then be replanted in the ground or in separate pots. Water the divided plants well and place in a shaded position to allow it to recover from the shock of being divided.
