Erinacea generally requires full sun exposure, well-draining gritty soil, and moderate to low water levels, mirroring its natural arid habitats. Common challenges include root rot from overwatering, and pests such as spider mites. In spring and summer, erinacea enters a growth phase, needing consistent but minimal watering. During autumn and winter, reduce watering as erinacea goes dormant. Protect erinacea from frost and ensure good air circulation to prevent pest infestations and disease.
