African thistle plants require full sun to partial shade and thrive in well-draining, loamy or sandy soil. Consistent moisture is important, but african thistle plants are drought-tolerant once established. Preferring mild temperatures, they face challenges like aphids and fungal diseases. Seasonally, african thistle requires extra care during harsh winters and may need protection from extreme cold. Summer is the peak growing season, necessitating regular watering. In spring, cut back any dead foliage, and reduce watering in autumn as growth slows.
