Lilies are a large family of flowering perennials grown from underground bulbs. The family contains numerous species including oriental, Asiatic, trumpet and hybrid lilies. Each species produces pink lilies in varying hues, from the palest ballet pink to deep cerise. Plant all summer flowering lily bulbs in much the same way. They are easy to establish and maintain if planted with care.
Select a planting location with a full sun, filtered sun or partial daily shade, depending on the specific needs of your variety of lily and your climate. All lilies require some sun to bloom.
Prepare a planting bed of nutrient-rich and deeply tilled soil. Use a hand trowel to churn up at least 12 inches of soil, and remove any hard clumps of soil or clay and any rocks that you find. Amend the soil with compost or well-aged manure. Mix in a dose of good-quality granular bulb fertilizer.
Plant your pink lily bulbs 8 inches deep in the soil or at a depth three times the height of the bulb. Position the bulb in the soil slope side up with the root plate facing down. Cover the bulb with the amended soil and pack down the soil around the bulb to ensure good contact.
Water your bulb deeply at planting and maintain evenly moist but not wet soil around the bulb throughout the growing season. Depending on the time of year and climate, you might have to water every day, once a week or even less. Do not allow the bulb to sit in standing water because it will rot.
Mulch over your planted and watered pink lily bulbs with a few inches of shredded bark, cocoa bean hulls or compost. Mulch holds moisture in the the soil, so you won't have to water as much, and it will keep weeds at bay.
