A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied once a month during the growing season. Be careful not to over-fertilize as this can lead to excessive foliage growth and reduced flower production.
Pruning
Pruning can be done to shape the plant, promote bushier growth, and remove dead or damaged stems. It is best done after flowering has ended. Cut back the plant by up to half its size, making sure to leave a few leaves on each stem. This will encourage the plant to produce new growth and flowers.
Propagation of Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis
Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis is a plant endemic to Kenya and Tanzania. It grows naturally in rocky soils and open woods, and it is commonly utilized in traditional medicine for its anti-inflammatory and antiseptic properties.
Propagation Methods
Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis can be propagated through seeds, cuttings, or division.
Propagation by Seeds
The seeds of Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis are small and can be sown directly into well-draining soil. They should be surface-sown and kept at a temperature of 20-25°C until they germinate. Once germinated, the plants should be watered sparingly to avoid waterlogging the soil.
Propagation by Cuttings
Propagation by cuttings is also possible for Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis. The cuttings should be taken from healthy and mature plants and should be about 10cm in length.

Disease and Pest Management for Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis
Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis is a herbaceous plant that belongs to the sunflower family. As with all plants, it is susceptible to various diseases and pests that can reduce its growth and yield. Here are some of the common diseases and pests that may affect this plant and the ways to manage them.
Diseases
1. Powdery mildew: This fungal disease appears as a white powdery coating on the leaves and stems of the plant. To manage it, remove and destroy the affected parts of the plant. Ensure proper ventilation and avoid overhead watering.
2. Leaf spot: This is another fungal disease that appears as circular brown or black spots on the leaves. To manage it, remove the infected leaves and ensure the plant's environment is well-drained to reduce moisture.
3. Root rot: This disease is caused by various fungal pathogens that attack the plant's roots, causing them to rot. To prevent it, ensure proper drainage and avoid overwatering. If the infection has already occurred, remove and destroy the infected plants and improve soil aeration and drainage.
Pests
1. Aphids: These are small, pear-shaped insects that suck the sap from the tender parts of the plant, causing stunted growth and distorted leaves. To manage them, use insecticidal soap, neem oil or introduce natural predators such as ladybugs.
2. Thrips: These are tiny insects that feed on the leaves of the plant, causing them to become distorted and withered. To control them, use insecticidal soap or introduce natural predators like mites or lacewings.
3. Whiteflies: These are small, white insects that feed on the underside of the leaves, causing yellowing and wilting. To manage them, use insecticidal soap, neem oil or introduce natural predators such as parasitic wasps.
In conclusion, managing diseases and pests is an essential aspect of maintaining healthy and productive Sphaeranthus ukambensis Vatke & O.Hoffm. var. ukambensis plants. A combination of cultural, physical and chemical methods can help prevent and control the spread of these harmful organisms.
