Once the seedlings have grown to about 8 cm in height, they can be transplanted into individual pots and then planted in the desired location.
Vegetative Means
Psiadia gnaphaliopsis Schweinf. & Volkens can also be propagated through vegetative means, specifically by stem cuttings. The cuttings should be taken from matured plants and should be about 10 to 15 cm long. The bottom leaves should be removed, leaving only a few at the top. The cuttings should then be dipped in a rooting hormone and planted in moist soil. The cuttings should be watered regularly and kept in a shaded area until they have rooted.

To manage these diseases, it is best to remove any infected plant parts and dispose of them properly. Avoid overhead watering and ensure proper air circulation around the plant to prevent the spread of fungal spores. Fungicides may also be used as a preventative measure or to treat the disease in severe cases.
Pest Management
Several insect pests can affect Psiadia gnaphaliopsis Schweinf. & Volkens, including aphids, thrips, and spider mites. Aphids are small, soft-bodied insects that can cluster on the undersides of leaves and suck the sap from the plant, causing distorted growth and yellowing leaves. Thrips, on the other hand, are tiny insects that feed on the flowers and buds, causing them to distort or drop. Spider mites, which are not actually insects but arachnids, can also be a problem, causing yellowing leaves and webbing on the plant. To manage these pests, it is best to monitor the plant regularly and take action as soon as any signs of infestation appear. Insecticidal soap or neem oil can be used to control aphids and thrips, while spider mites can be controlled using predatory insects or miticides. It is important to follow the instructions carefully when using any pesticides and to avoid using them during times when bees and other beneficial insects are active.
