Propagation of Bidens abyssinica Sch.Bip. ex Walp.
Bidens abyssinica Sch.Bip. ex Walp. can be propagated through various methods to expand the population of the species. Two effective methods of propagation for this plant include seed and vegetative propagation.
Seed Propagation
The most commonly used method of propagation for Bidens abyssinica Sch.Bip. ex Walp. is by seed. The seeds of the plant should be collected and sowed in well-prepared soil. The seeds should be sowed at a depth of 2.5 cm with a spacing of 30 cm and a row spacing of 60 cm. The seeds should be watered regularly and kept moist to germinate. The ideal temperature range for germination is 20-25°C.
The seedlings should be thinned down to 15 cm apart after they have grown to a height of 10 cm. The planting beds should be kept weed-free, and a balanced fertilizer should be applied to promote healthy growth. The plants should be watered regularly and protected from pests and diseases.
Vegetative Propagation

The basal end of the cutting should be dipped in rooting hormone powder, and it should be planted in a well-prepared planting bed with a spacing of 30 cm and a row spacing of 60 cm.
The planting bed should be kept moist to encourage root growth. The cuttings should be watered regularly and protected from pests and diseases. The plantlets should be transplanted to individual pots after 4-5 weeks after rooting, and they should be planted in the field after the last frost.
Disease and Pest Management for Bidens abyssinica Sch.Bip. ex Walp.
Bidens abyssinica, also known as the Ethiopian beggarticks, is a flowering plant that can be affected by several diseases and pests. Managing these diseases and pests is crucial for maintaining the health and vigor of the plant. Here are some common diseases and pests that might affect Bidens abyssinica and ways to manage them.
Diseases
One of the most common diseases that affect Bidens abyssinica is powdery mildew, which is caused by a fungal infection. Powdery mildew appears as a powdery white coating on the leaves and stems of plants. To manage this disease, it is important to promote good air circulation around the plant by spacing them adequately and removing affected plant parts. Fungicides can also be used to control severe cases of powdery mildew.
Another disease that can affect Bidens abyssinica is leaf spot, which is caused by bacteria or fungi. Leaf spot appears as dark, water-soaked spots on the leaves, which can later turn brown and cause leaf drop. To manage this disease, remove affected plant parts and avoid overhead watering, as this can spread the disease. Fungicides can also be used to control severe cases of leaf spot.
Pests
One of the most common pests that can affect Bidens abyssinica is aphids, which are small, soft-bodied insects that feed on the sap of plants. Aphids can cause distorted growth, yellowing, and stunted growth in plants. To manage aphids, you can spray them off the plant with a strong jet of water or use insecticidal soap. Predatory insects like ladybugs or lacewings can also be released into the garden to control aphids naturally.
Another pest that can affect Bidens abyssinica is spider mites, which are tiny pests that feed on the underside of leaves. Spider mites can cause yellowing, stippling, and webbing on leaves. To manage spider mites, you can spray them off the plant with a strong jet of water or use an insecticidal soap. Predatory mites can also be released into the garden to control spider mites naturally.
By managing diseases and pests on Bidens abyssinica, you can ensure the health and longevity of this beautiful flowering plant. Remember to always use the least toxic method available to manage diseases and pests, and avoid using broad-spectrum pesticides that can harm beneficial insects and other wildlife.
