It likes the half shade growing environment, but it can't be in the dark place, or the plant will be weak naturally, especially in winter, because the outside sunlight intensity is not so poisonous, so it can contact more sunlight to promote the healthy growth of the plant.
The plant is getting thinner and thinner, and the nutrition is not up to the requirements. There is not enough nutrition to supplement the growth. You can add fertilizer according to the growth trend. You can apply fertilizer every 7-10 days, but you don't need to apply it when you are dormant, otherwise it can't be absorbed normally, which will cause the root of the plant to rot.
Water supplement is also an important factor for growth. If there is no water supply for a long time, and there is not enough humidity supply for growth, there will be problems in the natural growth of plants. Water can be applied according to seasonal changes, once a day in spring, twice a day in summer due to strong light and strong evaporation, once every 2-3 days in autumn, and less in winter.
