Setup, Compatibility & Care

For the best results, plant your bulbs during the autumn or winter months in a location with fertile, well-draining soil. Dig a hole to a depth roughly three to four times the size of the bulb and space individual bulbs approximately 10 cm apart. If you are not planting them immediately upon arrival, it is critical to store the bulbs in a cool, dry, and well-ventilated location like a garage or shed. Ensure they are kept in a frost-free environment and protected from rodents. Once established, these perennials require very little maintenance, though removing spent flower stalks can help the plant direct energy into the bulb for the next season.
