Perform a soil pH test. Lilies prefer a pH of 6.5. Your county cooperative extension agent can advise you on how to adjust the pH of the soil in your area.
Plant the pink perennial lily bulbs in the fall, at a depth three times the height of the bulb. Cover lightly with soil and then cover with a 4-inch layer of mulch. Allow the mulch to remain over the winter, pulling it back when you see new growth in the spring.
Sprinkle 5-10-10 fertilizer on the soil in the spring and use a hand cultivator to scratch it into the top inch of soil.
Keep the soil moist to a depth of 6 inches at all times.
