Asiatic lilies are flowering bulbous plants commonly grown for their large, colorful flowers. They are easily identified by the small dots, or freckles, that adorn their petals. Asiatic lily flowers appear in colors of white, pink, yellow, red or orange and bloom during the summer months. Asiatic lilies are easy to grow in the home garden and require only minimal care to flower and thrive in most regions of the United States.
Plant Asiatic lilies during mid-spring in a location that receives full sunlight throughout the day. Spread a 2-inch layer of organic compost over the planting site and use a garden hoe to incorporate it into the soil to increase fertility. Space Asiatic lilies 10 inches apart.
Spread a 1-inch layer of mulch over the soil surrounding Asiatic lilies to insulate the soil, improve moisture retention and prevent the growth of weeds. Allow about 2 inches between the base of the lilies and the beginning of the mulch for the best results.
Water Asiatic lilies once per week during the first two months of growth to help the roots become established. Reduce the frequency thereafter to once every 10 days to keep the soil consistently moist. Never allow standing water to accumulate around Asiatic lilies, as bulb rot may occur.
Feed Asiatic lilies once per year in early spring using a high-phosphorous 5-10-5 NPK fertilizer. Apply following the manufacturer's directions for proper application and dosage. Water immediately after fertilizing to release the nutrients into the soil.
Remove faded or dead Asiatic lily flowers as soon as possible to conserve nutrients and encourage the formation of additional blossoms. Use your fingers to pinch off the flowers as close to the stem as possible to minimize damage.
