1. Root ramet

April, may or October is the best season. It can be carried out after the leaves are withered and yellow. First, remove it from the flowerpot, take out the root soil, and divide the rhizome into segments. Ensure that at least two to three bud holes are retained on each segment of rhizome, and the root system is retained, which can improve its survival rate

2. Separate planting and pot

Put the rotten fertilizer into the pot to be planted as the matrix, and lay a layer of soil with large particles at the bottom, such as perlite, which can speed up its drainage speed. It must be placed in the order of coarse first and then fine, so as to facilitate the absorption of nutrients by new plants. The divided rhizomes shall be buried in sandy loam, and the planting quantity shall not be too dense. One or two plants in each pot can be used, otherwise it is unfavorable to the later flowering. After planting, water a little and put it in a sunny place

3. Precautions

Do not water too much in the later stage, otherwise the root cannot breathe and is easy to rot. It should not be exposed to the hot sun. It should be placed in a semi cloudy place in summer. It should be maintained in the sunny place in late autumn. After frost, it needs to maintain the temperature of its environment at two to three degrees, which can help it survive the winter safely. When the temperature is low in January, it is necessary to check whether the rhizome is damaged by freezing. If there is freezing injury, adjust the room temperature in time. At the end of winter, loosen the soil properly and move it outdoors in April< a>
