Propagation of Nivenia diversifolia
Nivenia diversifolia, commonly named as yellow aster, is a deciduous herb that belongs to the family Asteraceae. It is native to Africa and found in tropical and subtropical regions. For gardeners and horticulturists who love to grow this plant at their place, its propagation is quite easy and can be done in several ways.
Propagation by Seeds
The most common method for propagating Nivenia diversifolia is by using its seeds. One needs to collect the seeds once the flowers have faded and dispersed their dandelion-like seeds. The seeds should be sown immediately after collection, and they will take approximately two weeks to germinate. One can sow the seeds in peat pots or directly into the garden bed. Nivenia diversifolia seeds are lightweight and require light to germinate. It is advisable to cover the seeds with a thin layer of soil to ensure that they do not dry out rapidly.
Propagation by Division
Another common method of propagating Nivenia diversifolia is by division. This method involves digging up the plant and dividing its roots into smaller sections, each with several shoots. One should use a sharp knife to ensure that each division has plenty of roots and shoots. The divided plant should be replanted at the same depth as before and watered adequately. This method is best done in the spring and is suited for more established plants that have been grown in the same spot for some time.
Propagation by Stem Cuttings
Propagation of Nivenia diversifolia can also be done by taking softwood stem cuttings during the summer months. The cuttings should be about 6 cm long and should contain two or three pairs of leaves. One should remove the lower leaves and insert the cuttings into a well-drained rooting medium. The medium should be kept damp, and the cuttings should be kept in a warm and humid environment. The cuttings will root in approximately 4-6 weeks.
Disease Management
Nivenia diversifolia is generally a hardy plant, but it is susceptible to several diseases. The most common diseases that might affect this plant are:

To manage this disease, it is best to remove the affected parts of the plant and dispose of them properly. Some fungicides can help to prevent powdery mildew from spreading.
2. Leaf spot:
Leaf spot is caused by a fungus and can cause yellowing and browning of leaves. Management of leaf spot involves removing the affected leaves immediately and disposing of them properly. Fungicides can also be used to prevent the spread of this fungal disease.
3. Botrytis blight:

They secrete a sticky substance called honeydew that can attract other pests and create ideal conditions for fungal diseases. To manage an aphid infestation, it is best to spray the plant with water to dislodge them or use insecticidal soap.
2. Spider mites:
Spider mites are tiny pests that can cause yellowing and mottling of leaves. They create small webs and can reproduce quickly, leading to a severe infestation in a short time. To manage spider mites, it is best to regularly check the plant and isolate any infested areas. Insecticidal soap or neem oil can be used for control.
3. Thrips:
Thrips are tiny insects that suck the sap from leaves and flowers. They can cause deformed and discolored growth. To manage thrips, it is best to prune and dispose of the affected parts of the plant. Insecticidal soap or neem oil can also help to control this pest.
