Place the lilies in an area with the highest light possible, but avoid glaring, direct sunlight. Moderately cool temperatures are best. Remove spent flowers. To enjoy Easter lilies year after year in the garden, plant them outside now in an area with bright light or with morning sun and afternoon shade. Lilies like their heads in the sun and their feet in the shade.
Good drainage is important.
A raised bed of organically enriched, loamy soil that is neutral to slightly acidic is ideal. Keep the soil moist. When the original foliage begins to die back, cut the stems back to about 3 inches above the soil surface. New growth will emerge. While the Easter lily is forced to bloom in March in time for the religious season, it will bloom in the garden sometime between April and May.
