Temperature Requirements
Osteospermum hispidum Harv. var. hispidum plant prefers moderate temperatures between 20°C and 26°C. The plant thrives in warm environments and does not tolerate very low temperatures. In winter, the plant may experience dormancy in areas with temperatures below 10°C.
Soil Requirements
The plant requires well-draining soil to grow and develop roots effectively. The pH of the soil should be slightly acidic or neutral (pH 6.0 – 7.5). The soil should be rich in organic matter with a good level of water retention capacity. Osteospermum hispidum Harv. var. hispidum grows well in sandy or loamy soil types. The soil should be moist but not waterlogged because waterlogging may lead to root rot.
Cultivation Methods
Osteospermum hispidum Harv. var. hispidum is easy to cultivate, even for beginner gardeners. The plant prefers well-draining soil with a pH of 5.5 to 7.5 and requires full sunlight exposure for optimum growth. It can be grown from seeds or cuttings and is suitable for both container gardening and outdoor gardens.
Watering Needs
Proper watering is essential for the healthy growth of Osteospermum hispidum Harv. var. hispidum. The plant requires regular watering, especially during the hot and dry seasons. It is recommended to water the plant moderately, allowing the soil to dry out between watering sessions. Avoid overwatering, as it can lead to root rot and damage the plant's health.
Fertilization
Regular fertilization is vital to ensure the plant's healthy growth and vibrant blooms. In the growing season, apply a balanced fertilizer every two weeks, following the manufacturer's instructions. Avoid over-fertilization, as it can reduce the plant's flowering performance and cause damage to its health.
Pruning
Pruning is not essential, but it can help to create a bushier and more compact plant. Deadheading the spent flowers regularly can also promote larger and more abundant blooms. To avoid damaging the plant, use sterilized pruning tools and cut just above a set of leaves or budding nodes. Perform the pruning during the growing season, and avoid pruning during the dormant period.
Propagation of Osteospermum hispidum Harv. var. hispidum
Osteospermum hispidum Harv. var. hispidum, commonly known as the African Daisy, is a popular flowering plant among gardeners. It is a great ornamental plant for borders, rock gardens, and containers due to its beautiful lavender-blue blossoms.
Propagation Methods
There are several methods to propagate Osteospermum hispidum Harv. var. hispidum. Some commonly used propagation methods are:
- Seeds: This is the easiest and most cost-effective method to propagate this plant. The seeds should be sown in trays or small pots filled with a well-draining potting mix. The trays should be kept in a warm and moist place until germination.
- Cuttings: Stem cuttings taken from mature plants during the growing season can be used to propagate the African Daisy. The cuttings should be around 10 cm long and treated with a rooting hormone before planting in a well-draining potting mix. Placing a plastic cover over the pot can help retain moisture and increase the chances of success.
- Division: This method involves dividing the mature plant into smaller sections and planting them individually. It is best to do this during the growing season as the plants will have enough time to establish and produce new shoots.

Disease and Pest Management for Osteospermum hispidum Harv. var. hispidum
Osteospermum hispidum Harv. var. hispidum, commonly known as the hairy Cape daisy, is a herbaceous perennial that is native to South Africa. Like any other plant, it is susceptible to a range of diseases and pests that can affect its growth and health. Here are some common diseases and pests that may affect the plant and ways to manage them.
Diseases
1. Leaf Spot: This is a fungal disease that appears as circular or irregular-shaped spots on the leaves. It can cause the leaves to turn yellow and fall off. To manage this disease, remove the affected leaves and avoid wetting the foliage while watering.
2. Powdery Mildew: This is a fungal disease that appears as a white powdery coating on the leaves. It can cause the leaves to become distorted and can stunt the plant's growth. To manage this disease, prune affected leaves, improve air circulation, and avoid overhead watering.
3. Root Rot: This is a fungal disease that affects the plant's roots, causing them to turn brown and mushy. It can cause the plant to wilt and eventually die. To manage this disease, ensure that the soil is well-draining, and avoid overwatering.
Pests
1. Aphids: These are small, soft-bodied insects that feed on the plant's sap. They can cause distortion of the leaves and stems and transmit diseases. To manage aphids, use a strong stream of water to wash them off, or apply insecticidal soap.
2. Spider Mites: These are tiny, spider-like insects that feed on the plant's sap, causing stippling on the leaves. They thrive in hot, dry conditions. To manage spider mites, ensure adequate moisture, prune affected leaves, and apply insecticidal soap or neem oil.
3. Thrips: These are tiny, black insects that suck the plant sap, causing distorted growth and browning of the petals. To manage thrips, improve air circulation, keep the soil moist, prune affected leaves, and apply insecticidal soap.
In conclusion, by incorporating these disease and pest management strategies, you can help ensure the health and growth of your Osteospermum hispidum Harv. var. hispidum plant.
