Cultivation and Management of Flower Cold Water Flower

Flowers like warm and humid climate, loose and fertile sandy soil, suitable for growth of 15 ℃ to 25 ℃, and no less than 5 ℃ in winter. Its specific management:

First, light management cold spray is a kind of indoor flowers with beautiful leaves, very shade-resistant, but prefer sufficient light, and should avoid direct glare. Flowerpots are placed in the north window in summer and in the south window in winter. If the light is too dark, the color of the leaves will fade; if the sun is too strong, the leaves will be burned.

Second, fertilizer and water management to master the principles of moisture management, basin soil to keep dry but not crack, moist but not wet is better. In summer, often spray water on the leaves to keep them clean and shiny. Spray less water on the leaves in winter, otherwise the leaves will appear black spots, or even black and rotten. Watering 28% or 37% liquid nitrogen fertilizer at a time in about two weeks during the growing period makes the plant strong. After autumn, increase the application of phosphorus and potassium fertilizer to strengthen the stem and prevent lodging.

Third, multipurpose cutting methods for reproduction can be carried out in both spring and autumn. When the number of families is less, the top of the stem is used as cuttings in May, and the medium is river sand or vermiculite. Under the suitable temperature (20 ℃ to 25 ℃), rooting takes place in about 10 days. When the new bud lengthens from 3 cm to 5 cm, put it on the basin with sandy soil. Pour enough water to fix the root and transfer to normal management.

4. Other management shall change the basin once a year. When the shape of the old plant is scattered and the ornamental value decreases, the seedling renewal is propagated by cutting in order to improve the ornamental value. At the same time, it can also reduce the harm of diseases and insect pests. In the case of poor ventilation, it is vulnerable to aphids. When the basin soil is muddy for a long time, the roots often rot, so attention should be paid to reasonable control of soil and water.
