Temperature Requirements
The plant Arctotis diffusa Thunb. grows best in warm climates. It can tolerate warm temperatures ranging from 70°F to 80°F, but it thrives in hot temperatures ranging from 80°F to 90°F. In cooler climates, the plant grows as an annual and may not survive frost. Therefore, it requires temperatures above the freezing point, with the temperature range between 40°F and 50F°F being optimal.
Soil Requirements
The plant Arctotis diffusa Thunb. grows best in well-draining, nutrient-rich soil. The pH of the soil should be neutral to acidic. Soil with a pH range of 6.0 to 7.0 is optimal for the plant's growth. The soil should be fertile and rich in potassium, nitrogen, and phosphorus. Soil with high clay content or compacted soil can hinder the plant's growth, leading to root rot or stunted growth.
Cultivation of Arctotis diffusa Thunb.
The Arctotis diffusa Thunb. is a species that is easy to cultivate, and it can adapt to different types of soils. The best soil for this plant is a well-draining soil mix with a pH level ranging from 6 to 7.
This plant requires plenty of sunlight to grow well, and it thrives in areas with full sun exposure. It can tolerate moderate shade, but it may not grow as well as it would in full sun.
If you're looking to enhance the blooming of this plant, planting it in a spot with good air circulation is ideal. The wind helps to encourage flower formation and petal movement.
Watering Needs of Arctotis diffusa Thunb.
Arctotis diffusa Thunb. requires regular watering to support its growth, especially during the blooming season. The soil should be kept moist but not waterlogged, as excess water can lead to root rot issues.
You can use a watering can or a garden hose to water the plant once a week. However, if the weather is hot and dry, the plant may require more frequent watering to ensure it stays healthy.
Fertilization of Arctotis diffusa Thunb.
Arctotis diffusa Thunb. benefits from regular fertilization to promote its growth and flowering. You can use a liquid or granular fertilizer that is high in phosphorus to support the development of flowers and to strengthen the roots.
Fertilize the plant every two weeks during the growing season to provide it with the necessary nutrients. Be careful not to over-fertilize, as this can damage the plant.
Pruning of Arctotis diffusa Thunb.
Pruning Arctotis diffusa Thunb. is not a necessity, but it can help to shape the plant and control its growth. You can remove the spent flowers to encourage the development of new blooms.

Diseases
1. Leaf Spot: Leaf Spot is caused by a fungal infection and is characterized by the appearance of brown spots on the leaves. To manage leaf spot, you should remove affected leaves and destroy them. Try to avoid overhead watering as it can cause the infection to spread. Fungicide treatment can also be used to control the spread of the disease.
2. Crown Rot: Crown rot is caused by a soil-borne fungus and is characterized by wilting and stem rot. To manage crown rot, you should avoid overwatering and provide good drainage. Remove and destroy infected plants and apply fungicide to the soil to prevent further infections.
Pests
1. Aphids: Aphids are tiny insects that suck the sap from plants and can cause stunted growth and distorted leaves. To manage aphids, you can wash them off with a strong stream of water or use insecticidal soap. Introducing natural predators such as ladybugs can also help to control aphids.
2. Spider Mites: Spider mites are tiny arachnids that can cause yellowing, wilting, and stunted growth. To manage spider mites, you can use insecticidal soap or neem oil. Increasing humidity levels around the plant can also be helpful, as spider mites thrive in dry conditions.
By following these disease and pest management tips, you can help to ensure that your Arctotis diffusa Thunb. plant remains healthy and vibrant. Remember to always carefully follow the instructions on any pest control products and to handle them with care.
