Dimorphotheca thrive in full sunlight and well-draining, loamy soil, with moderate water needs, emphasizing less frequent, deep watering. They prefer warm, mild climates and can have issues in extremely high temperatures or frost conditions. Common challenges include aphids, whiteflies, and fungal diseases like powdery mildew. Seasonally, dimorphotheca require protection from frost, reduced watering in winter, and might benefit from mulching to keep roots cool in summer.
