Plants in the genus erinacea typically prefer well-draining, gritty soil and a sunny location with ample light to thrive. Moderate watering is required, with a careful approach to avoid overwatering. To plant, select an area with appropriate sunlight, amend the soil with proper drainage materials if needed, and plant the erinacea at the same depth as in its previous container. After positioning, water the soil to help establish roots, but allow it to dry between watering sessions thereafter. Understanding the specific needs of your chosen erinacea species is crucial for optimal growth, as conditions can vary between species.
