Cultivation methods and precautions of Katu Red Sword

1. Maintenance methods

1. Soil: Katu Red Sword likes to grow in loose and fertile soil, and the best soil for planting is sandy soil.

2. Water: It has a very low demand for water and should not be watered too much. It is suitable for growing in moist soil. When watering, just spray some water appropriately.

3. Nutrients: Phosphorus fertilizer is generally used as fertilizer, and it should be applied as far away from the roots as possible to avoid the heat of the fertilizer burning its roots and stems.

4. Light: Katu Red Sword likes to grow in a diffuse light environment, half-day light is best. The light should not be too strong, as too strong light will cause its branches and leaves to fade and dry up, affecting its normal growth.

2. Breeding techniques

1. Pruning: When the branches and leaves are yellow or curled, they should be pruned appropriately. When there are weeds in the pot, they should be removed in time to avoid competing with the plants for nutrients.

2. Repotting: After about a year of planting, more roots will grow due to its continuous growth. At this time, you should replace it with a larger pot and add more soil.

3. Problem diagnosis and treatment

1. Root rot: Root rot is mainly caused by excessive watering and water storage in the pot. The accumulated water should be drained out in time and the rotten roots should be cut off.

2. Color change: The red color in the middle of the Katu Red Sword will no longer be red after being cultivated for a period of time. This is because the flowering period of the flower has passed and it has begun to fade. Don't worry, after a while it will slowly turn back to the original red color.

IV. Other issues

1. How to spend the winter: When cold air comes, move it indoors. The indoor temperature should not be lower than 16 degrees Celsius so that it can spend the winter safely.

2. Whether it can be exposed to rain: Katu Red Sword can be exposed to rain, especially in a hot and humid environment. The rain can water the water droplets on the center of its leaves, keeping the center of the leaves moist, which can better promote the leaf center to absorb water.
