1、 Watering
The newly bought Acorus calamus can be planted in the wetland or shallow water by the pool, with a depth of 6-8cm. After planting, keep the water depth of 4-5cm, so there is no need to manage it. You can also find a large-diameter flower pot for maintenance and keep water in the pot p>
2、 Illumination
Acorus calamus likes light and is also resistant to half shade, but poor light will affect plant flowering. Therefore, when raising Acorus calamus at home, we should let it see more sunshine. If the light is sufficient, it will grow vigorously and bloom more. Moreover, it is hot in summer. As long as we ensure sufficient water supply, we are not afraid of sun exposure p>
3、 Temperature
The most suitable temperature for the growth of Acorus calamus is 15-30 ℃. After the frost in autumn and winter every year, the stems and leaves on the ground will wither. We can trim the withered stems and leaves. The potted plants are also pruned to keep the soil moist and let it survive the winter safely p>
4、 Fertilization
The demand for fertilizer and water of Acorus calamus is not high. Just keep the soil fertile during planting, and it is best to choose neutral or slightly acidic soil. If the soil is alkaline, calcium superphosphate and potassium fertilizer can be mixed into the soil as base fertilizer during planting p>
5、 Disease
Acorus calamus is especially fond of soft rot and flower rot in hot and rainy seasons. When soft rot occurs, the color of the plant leaves will become pale, dry and black, and the underground stems will rot. Bordeaux liquid can be used to control it. When the flower rot occurs, it can be prevented and controlled with mancozeb. Before spraying, remember to clean up the rotten plants and eliminate the diseased plants to avoid infection p>
