In fact, the underground stem rot of vertical potted flowers is caused by excessive irrigation, especially in winter, ultra-low temperature and water storage are easy to cause the underground stem rot of vertical potted flowers. Therefore, in the process of watering the drooping water pagoda flowers, we must be careful not to store water, especially to maintain a suitable temperature in winter. This can prevent the drooping underground stems of water hyacinth from rotting.
The flowering water tower likes a warm, humid and sunny natural environment. Only under the illumination of a bright hall can it bloom normally and get the best-looking leaves. However, in summer, it is still necessary to avoid the exposure of the midday sun. The suitable temperature for growth and development is 20-30℃ in summer and 15- 18℃ in winter. If it is lower than 10℃, it cannot grow and develop, and it can maintain at least 5℃ at night. The drooping Sophora japonica is resistant to low temperature and can withstand the ultra-low temperature of 2℃ in a short time. The soil layer is composed of neutral or slightly acidic alkaline sandy soil mixed with humus or peat soil.
Pineapple likes high and low temperature natural environment, and the relative humidity of the air should be kept between 75% and 85%. Within the humidity range here, the plants will become smoother and rounder, and the leaves will become bright and attractive. When the environmental humidity is too low (below 50%), the leaves will roll inward or cannot bend and extend, and even the leaves will wither. However, the ambient humidity should not be too high. If the environmental humidity is high, brown spots will appear on the leaves of plants, and in severe cases, the heart will rot. The air humidity at seedling stage should be controlled between 80% and 85%, and it should be adjusted between 75% and 85% after three months of planting. Sprinkling water on the bottom of the planting bed and the aisle can improve the relative humidity of the air and also achieve the actual cooling effect.
Irrigation quantity can be controlled according to the change of time period. In the case of drooping water hyacinth developing and flowering, it is necessary to keep the humidity of the cultivation substrate moderately. But when the weather is very cold, besides adjusting the temperature, another main process is drainage. You can use the method of planting and breeding. Generally speaking, plants planted for more than three years, or plants with bulbs of more than eight centimeters, all collect seeds. After collection, prepare the culture medium in advance. With these methods, the germination rate is very high.
