Cutting is easy to take root, and the stems of plants that have been potted for more than 2 years are longer, so cutting off the stems can be combined with plastic cutting. In the middle and late April, cut the stem at the 2 ~ 3 nodes of the soil surface, and the top length is 10 cm. The lower part can be directly soaked in water at 28 ~ 30℃ for cutting. 1 ~ 2 weeks can take root, and every 2 ~ 3 nodes in the middle of the stem are one node, which can take root after being inserted into the seedbed of coarse sand or vermiculite at 25 ~ 30℃ for 3 ~ 4 weeks. Small plants are usually tillered at the base of plants. These small plants can be cut off in late spring and early summer, planted in coarse sand to keep moisture, and can take root in 10 days.
3. Cultivation points
Like high temperature, high humidity, scattered light and shade-resistant environment, the growth temperature is 20 ~ 30℃, and the overwintering temperature is above 10℃. It likes soil rich in humus and well drained. Potted soil is composed of 2 parts humus soil, 1 part garden soil, 1 part river sand and a small amount of decomposed manure or cake fertilizer, using soilless substrate. The growing season should be wet but not dry. When the temperature is higher than 25℃, the leaves should be sprayed with water frequently, and the water quantity should be controlled after autumn, so as to be moist when dry and properly aired in winter. It has strong fertilizer tolerance and should be properly fertilized. During the growing period, apply cake fertilizer water or 65,438+0% compound fertilizer solution twice a month, and stop applying fertilizer in winter. It likes to scatter light and avoid direct sunlight. Shading should be done at noon in spring and autumn and summer, and indoors should be placed in a bright place. In winter, the temperature is kept above 15℃. If it is lower than 10℃ for a long time, the leaves will die.
