The lily tree or Orienpet lily is not really a tree at all. But this large, striking plant can reach nearly 6 feet in height if well cared for and planted in a warm, well-drained site. Care for a lily tree much easier than many small ornamental trees its size. It simply needs regular watering and intermittent fertilization to produce impressive growth and unbelievably large blossoms.
Dig a hole that is just slightly wider than your bulb's roots. The hole should allow 6 to 8 inches above the top of the bulb. Plant neighboring bulbs 2 feet apart. Plant the bulbs in fall or early spring.
Water the planting area thoroughly so that the soil is moist (but not soaking) to the depth of the bulb. Use a wooden dowel to check the soil's moisture depth. Continue to check the soil's moisture level daily (twice daily in hot weather) and water whenever needed to keep the soil moist to this depth until the bulb germinates.
Spread a 2- to 3-inch layer of organic mulch around the planting area.
