It's better to choose the time of dividing plants. It's better to wait about three to four weeks after the lilies bloom and fail. It's about autumn. Time can not be too early, if the flower does not open before the operation, it will hurt the position of the bulbs and roots, resulting in a reduced probability of success.
At the right time, dig out the soil around it, and then don't knock against the bulb. It's better to use the help of a shovel, and ensure that it has some roots. Remove the soil next to the bulb, and then wash it in slow flowing water to ensure that the soil is removed.
Disinfect the knife, then cut the top of the bulb, about a centimeter above. Remove the peripheral lateral buds. Remove the lateral buds that are not fully grown. Do not keep them on top to prevent excessive nutrient consumption.
When planting in the field, select the planting location, and when potting, prepare the sandy soil with good drainage, which can ensure certain permeability and drainage, but also rich in humus. Plant the bulbs, the depth is about 10 - 15 cm, can be adjusted according to the size of the bulbs.
