Asiatic lilies are low-maintenance flowers that grow easily for most gardeners. Although not a fragrant flower, these lilies produce flowers in wide variety of colors, including red, orange, pink and cream, pointing in various positions depending on the cultivar. They range from 18 inches to more than 4 feet in height in USDA hardiness zones 3 through 8. They prefer full sun and moist, well-draining soil. Proper planting encourages rapid growth and ample blooming.
Plant your Asiatic lilies in the spring or fall for best results, suggests the National Gardening Association. Plant them as soon as you buy them, while they are still damp. Alternatively, store them for two or three days in damp paper towels until planting.
Dig a hole with a shovel to a depth of three times the length of the bulb, about 6 to 10 inches. Space bulbs at least 6 inches apart to ensure adequate root development and space for mature plants. Put bulbs in the ground with the pointed side facing upwards. Cover the bulbs with soil back to ground level. Firm down the soil with your hand or a trowel, taking care not to compress the soil too tightly.
Cover the area with 2 to 4 inches of an organic mulch. This retains moisture and keeps the soil cool in the summer. Keep the area well-watered and free of weeds, avoiding overhead watering. Consider planting a ground cover as an alternative to using mulch. This provides the same benefits without competing with and choking out the lilies.
Asiatic lilies also grow well in large, deep flower pots.
Use shorter lilies in containers for best results, while saving the taller cultivars for open spaces in the back of the flower bed.
Place a wire basket in the ground over the bulbs to keep gophers away.
Continue watering Asiatic lilies after they finish blooming, as bulbs grow throughout the year.
