1. LightingAcorus loves light. Whether it is planted in the ground near water or maintained in a potted plant, it must be planted in an area with good light. More sunlight is beneficial for the plant to accumulate nutrients and bloom and bear fruit. 2. TemperatureThe most suitable growth temperature for calamus is 20-25℃. If the temperature is lower than 10℃, calamus will stop growing. If the temperature is lower, the leaves of the plant will turn yellow naturally. The plant will hibernate in the soil as underground stems. 3. WateringPlant it in the ground near the water. Keep the main bud close to the soil surface when planting, and irrigate with 1-3cm of water. Find a large, watertight pot with a diameter of 40-50cm. After planting the rhizome, expose the growth point to the soil, add 1-3cm of water, and maintain a relatively stable water level. 4. FertilizationNo fertilizer is needed for ground planting, as pond mud itself is very fertile. Potted plants need base fertilizer applied to the bottom of the pot and topdressing 2-3 times. In the initial stage, nitrogen fertilizer is mainly used. Before heading and flowering, phosphorus and potassium fertilizers are used instead, and the fertilizers should be applied below 5 cm in the soil. 5. PruningBefore the arrival of winter every year, cut off the dead leaves on the above-ground part of the plant, clean it up, pour out the water in the pot, keep the soil slightly moist, and wait until the spring of next year to repot and divide the plant and replant it. 6. NoteThe calamus mentioned here is also called stinking calamus and water calamus. It has yellow flowers, but it does not stink. Instead, it has a fragrance. It is often used as a greening plant on the banks of waterscapes. It is not the ornamental variety Acorus calamus that is cultivated in the same genus. |
