The Popular Madonna Lily In The West
Although most lilies can be transplanted in September, it is desirable to plant Madonna lily bulbs in August. Madonna lilies start rooting at once and develop a small rosette of leaves before winter sets in, and these remain green throughout the winter. Unlike other lilies, the Madonna lily should be planted shallow. The bulb can be planted with the top of the bulb placed just underneath the soil, or somewhat deeper, but usually no more than two inches deep.
