Culture method of cold water spray

Lighting requirement

Cold water likes sunshine, but is afraid of bright light. Cold water should be kept in the shade in summer to avoid strong direct light. But make sure the maintenance site is bright. But if the light is too dark, the color of the leaves will fade. In the sparse shade environment, the cold water flower leaves are clear white and green, the internodes are short and compact, and the leaves are bright and shiny. In the all-overcast environment, the cold spray is often overgrown, the Internode becomes longer, the stem is soft, lodging easily, and the plant shape is loose.

Fertilizer and water requirement

Master the principle of wetting management, keep the basin soil dry and uncracked, moist but not wet. Spray water regularly to keep the leaf 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.

Temperature requirement

The suitable temperature for green cold spray growth is 18-22 ℃, and the overwintering temperature should not be lower than 7 ℃. Only at a suitable temperature, the plant grows rapidly and its value can be better reflected.

Pruning method

In order to enhance the pot ornamental effect of cold splash, the growing period should be pruned regularly to promote its branching and maintain full plant shape. If you want to cultivate into a small potted plant, you should pick the heart regularly and trim it properly to make it dwarf. Be careful not to prune too much, otherwise it will easily lead to many and small cold splash leaves, affecting the aesthetics.

When the cold splash plant grows to about 40 cm, the stem will lodge outward. It should be cut short in time to promote the emergence of new branches at the lower end of the plant so as to make the branches dense and compact.

The culture method of cold water flower is perennial herb, the stem is fleshy. Relatively hardy, winter room temperature not less than 6 ℃ will not be frozen, more than 14 ℃ began to grow. Like warm and humid climatic conditions, afraid of sun exposure, in a shady environment, the leaves are white and green, the internodes are short and compact, and the leaves are bright and shiny. In all shaded environments, it is often overgrown, the internodes become longer, the straw is soft, lodging easily, and the plant shape is loose. Lax requirements on the soil, can withstand weak alkali, more resistant to water and moisture, not resistant to drought. The specific culture methods of cold water flower are as follows: first, light management cold water flower is a kind of indoor flower with beautiful leaf color, which is very shady, but prefer sufficient light, and should avoid strong light. 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, the propagation method cold water splash propagation multi-purpose cutting method, spring and autumn can be carried out. 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. Culture method of cold water spray

Cold spray is a kind of indoor flower with beautiful leaf color, which is very shade-resistant, but prefers sufficient light and should avoid direct light. 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.

The basin should be changed when the temperature is about 10 ℃ in spring, and the basin soil should be rich in humus, loose and fertile loam. The plants should be pruned properly before changing pots, and the pots with poor plant types can be re-cut. Keep the basin soil moist, should not be too wet, otherwise the root is perishable, the air humidity requirement is higher, the leaf color is bright green and the pattern is beautiful under the higher air humidity.

Water spray should be often sprayed around it to increase air humidity. You can start fertilizing after seeing the new leaves come out. Rotten organic fertilizer should not be used too much urea, such as nitrogen fertilizer is easy to grow crazy, which is not conducive to the appearance of the plant. When the phosphorus and potassium fertilizer is insufficient, the markings on the leaves are easy to fade.

Master the principle of wetting management, keep the basin soil dry and uncracked, moist but not wet. In summer, often spray water on the leaves to keep them clean and shiny. Keep the basin soil moist and do not apply fertilizer when the temperature is high. 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.
