Fill the pot half full with a rich garden soil and add 2 to 4 fertilizer tablets, then continue to fill the pot with soil to about 2" from the top. The plant should be set upright with the roots buried gently in the soil. Make sure the growing tip of the plant is not buried. Next, add an inch or two of gravel or sand in order to prevent the soil from escaping from the container. Remember to keep the gravel away from the crown of the plant. The plant can now be lowered into the water to a depth of approximately 6 inches. As the plant grows, it can be lowered to a depth of 12 inches.Tropical lilies cannot tolerate cold temperatures and should not be planted until the water reaches a temperature of at least 70F. Planting too early can cause dormancy.
