The plant can tolerate high temperatures, but not the scorching sun, particularly during the summer season, which may cause sunburn to the plant. Similarly, the temperature should not be too low as the plant might not be able to survive in extremely cold temperatures. Winter temperatures below 5°C may affect plant growth and development.
Soil Requirements
Osmitopsis asteriscoides prefers well-drained and loamy soil rich in nutrients. The pH range of the soil should be between 6 to 7.5. Excess drainage or waterlogging may lead to root rot and ultimately plant death. Adding organic matter to soil can improve its fertility and enable better soil structure.
Cultivation

It requires well-drained soil and partial to full sun to grow to its full potential. The plant can propagate through seeds or cuttings, but it is easier to purchase a young plant from a reputable nursery.
Watering Needs
The plant needs regular watering to maintain healthy growth, but not too much to avoid waterlogging. It is advisable to water the plant when the soil is dry to the touch but not wilted. The frequency of watering will depend on the weather, with hotter climates requiring more regular watering.
Fertilization
Osmitopsis asteriscoides (P.J.Bergius) Less. requires nutrient-rich soil for optimal growth. You can use a slow-release fertilizer in early spring and early fall. Additionally, you can add organic matter like manure to the soil yearly to improve the soil's nutrient content.
Pruning
The plant requires minimal pruning, but you can trim the tips of the branches to maintain the desired shape. Avoid heavy pruning as it can damage the plant. The best time to prune the plant is in late winter or early spring before the new growth starts.
Propagation of Osmitopsis asteriscoides
Osmitopsis asteriscoides, commonly known as the Cape daisy, is a perennial plant species that belongs to the Asteraceae family. It is native to South Africa; these plants are popularly used as garden plants for their bright yellow and daisy-like flowers. Propagation of Osmitopsis asteriscoides is typically done through two methods:
Propagation by seed
Propagation of Osmitopsis asteriscoides by seeds is the most common method. This can be accomplished by sowing the seeds in a well-drained potting mix, under a light layer of soil, and watering them. The seeds should be planted at a depth of about 2 to 3 millimeters and should be kept in a warm and moist environment. Germination of seeds usually takes about 10 to 14 days.
Propagation by division
Another way to propagate Osmitopsis asteriscoides is through division. This method is most successful when dividing the plant in spring. This can be done by gently digging up the plant and dividing the clumps of stems and roots into separate sections. Each section should then be replanted into its separate pot filled with well-draining soil. Water the newly planted divisions thoroughly and ensure that they are kept in a warm and moist environment until new growth appears.
Disease and Pest Management for Osmitopsis Asteriscoides (P.J.Bergius) Less.
