1. Temperature. Calamus likes a warm climate, the specific range is 20-25℃. If the temperature is lower than 10℃, its growth will be affected, so try not to lower it below 10℃. However, its own cold resistance is relatively strong, and it can generally survive the winter without taking special measures.

2. Water. Calamus is a plant that likes moisture very much and is not drought tolerant. Therefore, during its growing season, it needs to be provided with sufficient water so that it can grow. If it is too dry, it will dry out easily. In winter, if the temperature is more suitable, you cannot completely skip watering.

3. Lighting. Mild astigmatism is best for it, but it can also grow in semi-shade. There should be no strong light, and it needs to be adjusted in time in summer.

4. Fertilize. Generally speaking, calamus does not require much fertilizer, usually once a month. Liquid fertilizer is available. When planting or repotting, you can also mix some base fertilizer into the soil.
