Because it is attached to the trunk or in the dark and humid gap of its origin, its growth and development need cool and humid environmental conditions. It belongs to short-day plants and needs 8 to 10 hours of sunshine every day.

During the growth of Cynthia in one year, there are two short dormancy periods (one in the hottest summer and one after flowering in early spring) and two vigorous growth periods (one in the middle and late May and one in the middle and early June of 10). In the autumn growing season, attention should be paid to placing potted rattan in a sunny window to fully accept the sun. It is best to build a plastic film shed in the corner of the balcony to avoid the wind and sun. When the sun shines on the plastic shed, a microclimate is formed in the shed, which can ensure enough air humidity and is beneficial to the growth of Cynthia. On the other hand, the plastic film shed can increase the temperature and play a role in heat preservation, which is about 5℃ higher than that indoors at night. If there is sun, the temperature is 5- 10℃ higher than outside. In the cold winter, you can cover the plastic shed with waste cotton tires or blankets at night and open it at sunrise the next day. In this way, the temperature can be kept at about 15-20℃ during the day and not lower than 5-8℃ at night, which is beneficial to its growth.

When Cynthia Bian enters the budding stage, the supply of fertilizer and water should be sufficient. In particular, it is necessary to apply more phosphorus and potassium fertilizers and less or no nitrogen fertilizers. This is mainly to prevent overgrowth and affect the formation of buds. Generally, it is applied once a week with fully decomposed chicken manure, fishy water and bone meal. Don't water it too often. It is advisable to water it after the soil in the basin is dry. In addition, pay attention to the sparse buds on Cynthia. Buds usually begin to form in the middle and late June of 10. 2-3 buds often grow at the top of the stem node at the same time. At this time, it is necessary to dilute the buds, keep the largest and remove the rest. Sometimes, a young stem and a bud grow at the top of the stem node at the same time. It is necessary to pick young stems in time and grind them off with a snow axe to prevent the buds at the top from wilting due to insufficient nutrition.
