Care and Maintenance
Plant the base of the bulb at a depth three times the height of the bulb. This species typically emerges in late Summer or early Fall, so it can accept some water in the warmer part of the year. Stop watering once the leaves begin to turn brown, but keep leaves on the plant until they turn completely brown.
