Plant Lilies either in fall or early spring, 8-10" apart 3 times as deep below surface of ground as the bulb is high. If the bulb is 2" high, its bottom should be 6" below ground level. All lilies prefer light, loamy soil with a deep organic mulch, and require good drainage. Fertilize at beginning of growing season to encourage larger plants. If the season is dry, keep ground moist but not wet by watering thoroughly once a week until plants flower. After flowering, reduce water and allow them time to dry. Lilies are great naturalizers so with proper care they will continue to multiply. If the plants become crowded over time then it's best to dig and divide after they have hardened off at the end of the growing season.
