Watering: Water more when the weather is hot, keep the cultivation soil moist at all times in spring and autumn, and water less in cold weather. Soil: Try to use sandy loam when planting. Well-drained soil is more conducive to its growth. Fertilization: Apply phosphorus and potassium compound fertilizer once in early autumn, mainly nitrogen fertilizer after flowering, and do not fertilize at other times. Light: There should be sufficient light during maintenance. In order to avoid sunburn in summer, be sure to pay attention to shade. Note: Pay attention to ventilation in winter to avoid a stuffy environment.

1. Watering

1. Watering

In spring and autumn, watering only needs to keep the soil slightly moist. In summer, when the water evaporates quickly due to high temperatures, you can water more appropriately. The best time to water is in the morning. Or in the afternoon when the sun is not very strong. Growth is very slow in the cold weather in winter, so water as little as possible to prevent freezing damage and water accumulation.

2. Soil

In terms of soil selection, in order to better cultivate its fleshy roots, it is best to choose sandy loam soil for cultivation. At the same time, the drainage performance of this soil It is also very good and can greatly reduce the possibility of root rot caused by water accumulation.

3. Fertilization

During the growth period, in order to ensure that it can better differentiate its flower buds, a phosphorus-potassium compound fertilizer should be applied once in early autumn. After flowering, nitrogen fertilizer is generally used. At this time, the main focus is on growing branches and leaves. Ensure the nutrients it needs for growth and try not to fertilize at other times.

4. Lighting

When raising it, it should be placed in a sunny place for maintenance. In summer, pay attention to shade to prevent sunburn. If its leaves turn yellow, it is likely to be caused by excessive sunlight. In winter, as long as there is enough light and a suitable temperature indoors.

5. Precautions

When breeding indoors in winter, pay attention to ventilation. If the air is not circulated, pests and diseases are likely to occur. When watering it, be careful not to accumulate water. Root rot caused by water accumulation will cause leaves to fall, seriously affecting the flowering of the next year.
