Choose a location for the Asiatic lilies that provides plenty of direct sunlight.
Use soil that is well-drained with a 6.5 pH. Amend the soil with compost or manure to increase the richness and improve drainage.
Add a layer of mulch to the base of the lily plants to keep the soil cool and moist.
Give the lilies up to 2 inches of water per week and more during dry or hot weather. The soil 1 inch below the surface needs to feel dry before you water them.
Once the petals on the flowers start to drop, snip off the blooms with a pair of pruning scissors. Once the foliage starts to wither in the fall, it can be pruned to the ground.
Once the plant has been pruned down, add 5-10-10 fertilizer in a circle around the plant. Place a 4-inch layer of straw mulch over the plant to protect the bulbs from the cold.
